WebFXTreeAbstractNode
Abstract object with common functions and methods shared by WebFXTree and WebFXTreeItem.
The two of those inherites from this object.
Constructor
Abstract object - no instances of it should be created

Methods
| Name |
Returns |
Description |
| add(oNode, [bNoIdent]) |
Reference |
Adds a tree item to the current item. This method takes two argument, the first
is the WebFXTreeItem object to add and the second is an optional boolean value,
that if specified and set to true will prevent the tree from executing the indent
method automatically once the node has been added. This parameter has no effect
on calls to the add method before the tree is rendered, but settings this flag
when adding nodes after the tree has been rendered will greatly reduce the time
needed to complete the operation, this can be quite useful while adding more
than one node at a time, but requires that the indent method is manually executed
on the top most node affected by the changes afterwards.
Returns a reference to the added node. |
| indent() |
Void |
Redraws the traces between nodes and makes sure the tree is properly layed out. |
| toggle() |
Void |
Toggles the expand/collapse. |
| expand() |
Void |

Void |
Collapses the tree item. |
| expandAll() |
Void |
Expands the tree item and all sub items recursively. |
| collapseAll() |
Void |
Collapses the tree root and all sub items recursively. |
| expandChildren() |
Void |
Expands all sub items recursively (same as executing expandAll and the collapse). |
| collapseChildren() |
Void |
Collapses all sub items recursively (same as executing collapseAll and the expand). |
| getNextSibling() |
Reference |
Returns a reference to the next sibling. |
| getPreviousSibling() |
Reference |
Returns a reference to the previous sibling. |
| toString() |
String |

Ederson injury update ahead of Man City's huge clash with Chelsea
Ederson is set to return to the Manchester City team for their Premier League clash with Chelsea on Saturday after recovering from injury.
The injury, which was only described as a ‘muscular problem’ by City boss Pep Guardiola, kept Ederson out of the 3-1 defeat to Liverpool.
It also saw him substituted during the Champions League draw with Atalanta which ended with Kyle Walker in goal after Claudio Bravo was sent off.
However, City’s goalkeeping woes appear to be at an end after Ederson was pictured in training on Tuesday.
The Brazilian now looks like he will be back in first team action, as expected, at home to Chelsea in the 5.30pm kick-off on Saturday.
Guardiola said after the Liverpool defeat on 10 November: ‘Now he’s going to Brazil to recover there, when he comes back hopefully he’ll be fit.’

The Premier League champions are fourth in the table, one place and one point behind Chelsea, and will be desperate to get back to winning ways against the Blues.
They remain without long-term injury concerns Leroy Sane, Aymeric Laporte and Oleksandr Zinchenko for the game at the Etihad, and will also be missing Bernardo Silva through suspension.
However, Guardiola has Rodri and David Silva available to him again after injury.
City are already nine points behind Liverpool in the title race and cannot afford another slip up as they host a side that has won their last six Premier League games on the spin.

_The_In_Crowd_ (PG-13) * (out of ****)
"What would you do to get in?" Apparently not much at all--that is, if Warner Bros.' poster for _The_In_Crowd_ is posing the question to audiences in reference to seeing this youth-aimed thriller. At the showing I attended in the middle of a very hot summer afternoon, there were only about 15 people in the auditorium, including myself. Still, that's about 15 more people than will show up a week for now, for it won't be long before this sloppy, predictable potboiler finds itself completely on the outs with paying moviegoers.
We first meet heroine Adrien (Lori Heuring) as she is being discharged from St. Anastasia's, a mental institution. (The reasons for her stay is one of the film's not-terribly-enticing mysteries.) Thanks to a kindly doctor (Daniel Hugh Kelly), Adrien gets a job at a swank country club that's a popular summer hangout among the elite college crowd. While most of this "in crowd" turn up their nose at Adrien, the group's ringleader, "luscious brunette" Brittany (Susan Ward) takes a surprisingly immediate liking to Adrien.
Of course, the reasons for Brittany's interest in Adrien are shrouded in secrecy, and once they are revealed, audiences will have trouble either keeping themselves from rolling their eyes or stifling a yawn. But for a while, director Mary Lambert and writers Mark Gibson and Philip Halprin suggest something a bit more provocative. The two initially bond after Brittany fakes a suicide attempt in a pool, and Adrien "saves" her with some mouth-to-mouth. Later, Brittany bails Adrien out of trouble with her boss by implying she had her hands full--with her. Then on a hot night on the dance floor, the two seem a lot more interested in getting down with each other than a guy who manages to squeeze his way between them.
But this is a PG-13 movie, so this bit of shameless (and, I must admit, rather amusing) audience pandering doesn't go quite far enough to give the entire film a kinky watchability. Before long, Brittany spies Adrien having coffee with the hunky tennis pro (Matthew Settle) she'd had her eye on, and suddenly all the warnings Adrien had been given about Brittany's true nature appear justified. People start to have mysterious accidents, and Adrien finds herself in danger of being sent back to the loony bin.
Theoretically, _The_In_Crowd_ should build some momentum at this point, but the plotting is so pedestrian and the execution generally so ho-hum that it's impossible to care. So one is left to savor the few guilty pleasures available: some campy catfighting between Adrien and Brittany, and the lightly entertaining performance of _Sunset_Beach_ alumna Ward, who plays a vixen with verve. Like the others, there's no real meat to the character of Brittany (the fact that one of her defining characteristics is a weakness for lip gloss says it all), but at least Ward has some fun with her part.
Moviegoers, however, will find it just about impossible to have much fun with _The_In_Crowd_. It's fairly slow-moving, and after a long buildup, the promised thrills never arrive. Unfortunately for Warner Bros., the hoped-for teen audience will never arrive, either.

Docker != VM
Despite the growing use of containers over recent years there is still some confusion as to the difference between a container and a virtual machine. Most people understand they are both virtualization technologies but are a little hazy on the differences.
The aim of this repo is to help clarify the difference. In a nutshell, the difference is a VM seperates the kernel, file system and networking stack from the host machine. Docker separates only the file system, networking stack and uses a thing called cgroups to isolate the process(es) from the host machine. With Docker both the container and the host use the same kernel.
You are welcome to clone/fork and play with the code examples as you see fit. Some people (myself included) learn best by playing with things themselves.
Contained in the repo are multiple containers that all implement the classic “Hello World!” program. It’s so classic even Docker uses it as the validation step to prove Docker has installed correctly.
Each container implements the “Hello World!” program in a different language, or a different version of a language. By looking at the differences of each container I’ll explain what a container is and clear up the confusion.
Let’s begin by seeing what these containers do. This isn’t a primer for Docker, so I’m not going to explain how to install or use it. By using docker-compose
we can run all the containers in parallel and get the following output:
$ docker-compose up
...
Attaching to golang-1.10, node, golang-1.10-stripped, python3, python2, nasm, bash
golang-1.10 | Hello world!
node | Hello World!
golang-1.10 exited with code 0
golang-1.10-stripped | Hello world!
python3 | Hello world!
python2 | Hello world!
node exited with code 0
golang-1.10-stripped exited with code 0
python3 exited with code 0
nasm | Hello world!
bash | Hello world!
python2 exited with code 0
nasm exited with code 1
bash exited with code 0
What we see from each container is two things, that it prints “Hello World!” and the exit code for that container. Eagle-eyes readers will note that nasm
is the only one with an exit code of 1, I’ll explain that later.
There are 7 implementations of the “Hello World!” program written in Python2, Python3, Golang 1.10, Node, Bash and ASM (aka nasm
which is assembler). They are all literally or effectively one line programs and only print the string “Hello World!”. The only thing each container uses is 12 bytes for the string and however many bytes for the print instruction.
 The smallest is 356B, the largest is 81.3MB! Why such a big range?
It’s the programming language runtime and it’s dependencies. For each programming language there is code automatically added to the code your wrote to make your code run, that’s called the runtime. That runtime needs certain things from the operating system to run, so those need to be included too.
Remember, all that is happening is we are printing a 12 byte string. OK, you can add a byte or 2 for the line feed (and/or carrage return). Add in the print instruction and the total size is a 10s of bytes. Maybe a 100 bytes. Why are these containers so big?
Lets look at each programming language to see what is being included.
Python
Remember that each container has a separate file system from it’s host. That literally means there are two copies of /etc
, /usr
, /var
, and so on, one for the host and one for the container. Now, the container doesn’t have to contain any files or directories. But it must contain the ones it depends on.
Python depends on a lot. For all practical purposes it depends on a full OS. It certainly depends on a lot of system libraries. Python 3 and Python 2 rank #1 & #3 for the biggest containers. A possible reason for this is that the container is based on a “full” OS. You can use docker run --rm -it size/python:2 bash -l
to take a look at what files are in this container. The OS this image is based on is Alpine 3.7. How big is that image?
$ docker images alpine:3.7
REPOSITORY TAG IMAGE ID CREATED SIZE
alpine 3.7 bc8fb6e6e49d 31 hours ago 4.21MB
So Alpine is just over 4MB. Where does the other 54MB (Python2) and 77MB (Python3) come from? That is the Python runtime.
To be fair Python does describe itself as a “batteries included” programming language. And it is a syntactically light and very flexible programming language. Python does a lot of heavy lifting for the programmer and the runtime is the muscle that does that lifting. Python sure has some big muscles. 💪
Node
Node takes the #2 spot in our Docker image size leader board. Like Python, the Node container is based on Alpine 3.7. And like Python the vast majority of the image size is the Node runtime.
Node, like Python, does a lot for the programmer and does so using Javascript! If you use Chrome (or any modern browser) you might be amazed Node does so much with so little! 😵
Bash
Compared to the previous scripting languages Bash is tiny. It’s no bigger than the Alpine image it is based on. But it’s hardly a fair comparison to Python and Node. To do much more with Bash would require installing additional applications and using Bash to interact with their CLI.
Golang
This is the first of the compiled languages. It’s the first language to leave the MB territory and enter the KB. But to do that there are a few tricks.
Docker isolates one or more processes from the rest of the host, making only the kernel - and only some of it system calls - available. Because Golang is compiled we can drastically reduce the dependencies using a multi-stage Docker files. This means using one “fat” container to build the executable and then copy that exectuable into an empty container.
But wait, if all Golang is doing is printing a string to the screen, and that should take 100 bytes or so, why are the Golang containers 1.2MB and 750KB?
Once again, it is our old friend the runtime. While Golang does not do “as much” for the programmer as Python or Node, it still does a lot.  The stripped version of the container is using certain compiler flags to remove unnecessary code.
Assembler
And finally the winner for the smallest Docker image. 300B almost 1000x smaller than the next smallest. Like the Golang images, this image is built using a multi-stage Dockerfile so that only the executable goes into the final image. Because it is assembler the programmer has to do everything. On the flip side that means our container has almost nothing more than the instruction to print and the 12(-ish) bytes to print.
Now to explain that exit code. There are 3 things you need to know.
- I am not a software developer by trade (although I can code in multiple languages with the help of Stack Overflow )
- The last time I wrote any assembler was back in University, over 20 years ago 😱
- I had no idea what I was doing in assembler then and still have no idea now!
It is for these reasons that the nasm
container exits with a code of 1. It should not, but I have no idea how to fix it. Fortunatly it’s does not matter.
What does this all mean and why should you care
By looking at different programming languages we have learned that a container does not need to contain anything but the exact code it needs to operate. It needs no files (other than the executable), directories or anything else supporting it. Depending on the programming language you maybe forced to included an OS (everything but a kernel). Scripting languages like Python and Node can suffer from needing to “download half the Internet” before they can do anything useful.
The programming language you choose can have a massive impact on your containerized infrastructure. A system based on images that are MB will always be cheaper and more responsive than a system based on images that are GB. Storage maybe cheap, but would you rather be waiting to download a 1GB image or a 1MB image before your service is online?
To be clear. I am not advocating you must use a compiled language to get the “full benefit” of a container. Node and Python have their place, just as Golang does. And there are techniques you can use in the Dockerfile to minimise total image storage (and transfer).

TRIAL BY JURY A film review by James Berardinelli Copyright 1994 James Berardinelli
Rating (0 to 10): 4.0
Date Released: 9/9/94 Running Length: 1:47 Rated: R (Violence, language, mature themes)
Starring: Joanne Whalley-Kilmer, Armand Assante, Gabriel Byrne, William Hurt, Kathleen Quinlan Director: Heywood Gould Producers: James G. Robinson and Chris Meledandri & Mark Gordon Screenplay: Jordan Katz and Heywood Gould Cinematography: Frederick Elmes Music: Terence Blanchard Released by Warner Brothers
It never ceases to amaze me how badly a poor script can screw up a potentially fascinating premise. Exhibit one for the prosecution: TRIAL BY JURY.
 She has every intention of following her conscience until a little visit from Pirone's henchman Tommy Vesey (William Hurt) gives her something to think about. If there's a mistrial, he claims, she and her son (wooden child actor Bryan Shilowich) will be protected. If Pirone goes to jail, both of them will die.
As the trial progresses, the evidence against Pirone mounts until no reasonable juror could consider him anything but guilty. So Valerie is faced with an unpleasant--and potentially deadly--choice: acquit and live, or convict and risk death.
The theatrical and television previews make this film look like a clever thriller centered around this dilemma. But, as is often the case, that's because such advertisements use only the best scenes. Left out are numerous instances of overacting, underacting, terrible dialogue, and poor plotting.
Despite a compelling basis for its story, Jordan Katz and Heywood Gould's screenplay vacillates between the contrived and the downright moronic. The characters are strictly one-dimensional types engaging in flat, stilted conversations. Melodrama suffuses several potentially-taut sequences, and the conclusion would be right at home in such films as BASIC INSTINCT.
Aside from a brief appearance by character actor Mike Starr (who plays a witness for the prosecution), Armand Assante gives the only noteworthy performance. His often-magnetic (and never subdued) presence only makes you aware of what this film might have been had a more competent production team taken charge.
Unfortunately, Joanne Whalley-Kilmer is unable to carry to burden of the lead role. For whatever reason, grasping Valerie's psyche seems beyond the actress (or maybe she just didn't care enough), and she comes across as stale. The only thing striking about Whalley-Kilmer is the array of glitzy outfits she gets to wear.
Kenneth Branagh's DEAD AGAIN took a dopey premise and built a solid, entertaining plot around it. TRIAL BY JURY manages to do the opposite. Even as an homage to '40s film noir flicks, it's woeful. You need more than Joanne Whalley-Kilmer doing a Rita Hayworth impersonation to accomplish that.
Quentin Tarantino's much-awaited second feature won't be in theaters for another two months. Apparently, however, TRIAL BY JURY has chosen to herald that picture. After all, the script for this film is nothing if not pulp fiction.

There are horror films that come with expectations, namely to spook and scare us with the unknown. And then there is Stanley Kubrick's misguided though definitely spooky "The Shining," a horror film that is unaware of what it wants to say or how to say it. I admire Kubrick greatly, he is one of the finest directors in the history of cinema, but this film is definitely on a lower standard than some of his other works.
The problem is mainly Jack Nicholson, playing the wild-eyed, seemingly mischievous Jack Torrance. He has been hired as the caretaker of the Overlook Hotel, stationed in a highly remote, isolated area of Colorado. There is definitely something wrong with Jack from the start, he rolls his eyes and hardly flinches when hearing a past story of a graphic murder that took place at the hotel. His wife, Wendy, (a frail-looking Shelley Duvall) and their son, Danny (Danny Lloyd), who talks to his finger referred to as "Tony," come to stay with Jack at the Overlook for several months so of course, something will go wrong. There are several hints of this at the beginning of the film, most telling example is when Jack is driving the family to the hotel and mentions a cannibalism that occurred in the area. Wendy looks at him in disbelief, and Danny, seated behind them, says "it's okay Mom. I saw it on television." Jack replies, "You see. He saw it on the television."
"The Shining" is essentially about those long, wintry months spent at the Overlook, and the isolation is clearly felt from frame to frame. Most the months are broken up by titles that indicate the days of the week. Jack's madness begins to settle in, as he screams at Wendy for intruding while he is at work on a novel. Then he begins to see ghosts, such as a beautiful naked woman in a tub in one of the rooms of the hotel, and a bartender from the 1920's whom Jack tells about his fears and insecurities with his family, casually mentioning his wife as the "sperm bank upstairs."
"The Shining" could be a conventional horror film but there are enough eerie moments to make it a cut above the rest. But from Kubrick, I expected so much more than the conventional route it takes.  All of this is what one would expect from a Hammer horror flick but under this master's hands, it all comes off as typical shock tactics rather than real scares.
The other problem is the over-the-top performances that undermine credibility and cause us to lose sympathy with the characters. Jack is typical Jack, wild and insolent, seeming like an insane madman from the very start rather than a character study of a man slowly losing his sanity. Shelley Duvall tries her best I suppose but her screams and gaping looks are grating and cumbersome - she does better in her quiet scenes, such as the first scene between her and Danny discussing the trip to the Overlook. Danny Lloyd comes under the rule of why kids should not be cast in horror films - he simply stares into oblivion during his "shinings" and makes rather offputting gestures with his finger, mimicking the voice of "Tony." I know that this is all in the Stephen King book, but that is why adaptations exist - to change material that is often best left to the imagination rather than making it literal.
There are several virtues to "The Shining." The film has an ominous, otherworldly quality that is well-suited for such a disturbing horror tale. There are the particularly ominous opening helicopter shots of the roadways leading to the Overlook. The colors of the hotel are mostly gold and pink, thereby evoking the 1920's atmosphere of the ballroom. There are the point-of-view shots of Danny riding in his bike through the corridors and hallways, all accomplished with a Steadicam (one of the first films to use such a camera). There is one truly horrifying scene where Danny sees twin girl ghosts who ask him to come and play, immediately realizing they were the girls who were killed in the hotel by the former caretaker. There is a brilliantly edited and shot chase through the hedge maze outside the hotel where Jack torments poor Danny. In terms of production design, art direction, cinematography and sheer atmosphere, "The Shining" is triumphant in all departments.
But it is a horror film without the horror - more like a mystery with lots of hidden meanings in every shot (the haunting final scene justifiably asks more questions than answers). Its histrionic performances and overdone chilling musical score negates the horror and turns it into a freak show with occasional moments of terror. It's passable Stephen King horror but from Kubrick, one expects something much more challenging and thought-provoking.

Places (C++)
Overview
The Places API allows users to discover places/points of interest and view details about them such as address and contact information; some places may even have rich content such as images and reviews. The Places API also facilitates management of places and categories, allowing users to save and remove them.
Place Definition
A place is a point of interest, it could be a favorite restaurant, a park or someone's home. A QPlace object represents a place by acting as a container for various information about that place.
This information can be divided into 2 broad classifications
- Details
- Rich content
The place details consist of properties of the place, such as the name, location, contact information and so on. When a place is returned during a search, these details are filled in. Sometimes in order to save bandwidth, there are further details about the place that can be retrieved on an individual place by place basis, if the user is interested. The QPlace::detailsFetched() function can be queried to see if all available details have been fetched, and if not, QPlaceManager::getPlaceDetails() can be used to retrieve them. Precisely which details are populated during a search and which need to be fetched individually may vary from provider to provider. See plugin documentation for more details.
The rich content of a place consists of items such as images, reviews and editorials. Potentially there may be many rich content items, so they are treated separately from the place details. They can be retrieved in a paged fashion via QPlaceManager::getPlaceContent(). If necessary, the content may be assigned to a place so it can act as a convenient container.
Common Operations
Initializing a Manager
All places functionality is facilitated by a QPlaceManager instance. One must specify a QGeoServiceProvider in order to create the QPlaceManager
//The "provider name" is used to select a particular provider QGeoServiceProvider *provider = new QGeoServiceProvider("provider name"); QPlaceManager *manager = provider->placeManager();
Discovery/Search
In order to perform a search operation we simply create a QPlaceSearchRequest and set the desired search parameters, such as a search term and search center.
//instantiate request and set parameters QPlaceSearchRequest searchRequest; searchRequest.setSearchTerm("ice cream"); searchRequest.setSearchArea(QGeoCircle(QGeoCoordinate(12.34, 56.78))); //send off a search request /*QPlaceSearchReply * */ searchReply = manager->search(searchRequest); //connect a slot to handle the reply connect(searchReply, SIGNAL(finished()), this, SLOT(handleSearchReply()));
The request is an asynchronous operation so we need a slot to handle the completion of the request. In the handler we check that there are no errors and that our search result type is a place. If so we can then retrieve some of the core details of the place. At the end of the slot, we delete the reply since they are for single use only.
void handleSearchReply() { if (searchReply->error() == QPlaceReply::NoError) { foreach (const QPlaceSearchResult &result, searchReply->results()) { if (result.type() == QPlaceSearchResult::PlaceResult) { QPlaceResult placeResult = result; qDebug() << "Name: " << placeResult.place().name(); qDebug() << "Coordinate " << placeResult.place().location().coordinate().toString(); qDebug() << "Street: " << placeResult.place().location().address().street(); qDebug() << "Distance: " << placeResult.distance(); } } } searchReply->deleteLater(); //discard reply searchReply = 0; }
Note: Depending upon the plugin backend that was chosen, the search results may contain places which have further details that can be fetched on a place by place basis. To fetch these other details see Fetching Place Details.
Recommendations
Recommendations can be retrieved by supplying a place id via QPlaceSearchRequest::setRecommendationId(). Any places similar to the given place are retrieved.
Paging
If the plugin supports paging, the limit parameter may be provided to the search request.
QPlaceSearchRequest searchRequest; searchRequest.setLimit(15); //specify how many results are to be retrieved.
Fetching Place Details
A place that has been returned from a search request may have more details that can be fetched. The following demonstrates how to check if there are further details and if so how to request them.
if (!place.detailsFetched()) { /*QPlaceDetailsReply * */ detailsReply = manager->getPlaceDetails(place.placeId()); connect(detailsReply, SIGNAL(finished()), this, SLOT(handleDetailsReply())); } ... ... void handleDetailsReply() { QPlace place; if (detailsReply->error() == QPlaceReply::NoError) place = detailsReply->place(); detailsReply->deleteLater(); //discard reply detailsReply = 0; }
Fetching Rich Content
Rich content such as images and reviews is retrieved through the manager and then if required assigned to a place.
QPlaceContentRequest request; request.setContentType(QPlaceContent::ImageType); request.setPlaceId(place.placeId()); request.setLimit(5); /*QPlaceContentReply * */ contentReply = manager->getPlaceContent(request); connect(contentReply, SIGNAL(finished()), this, SLOT(handleImagesReply()));
We can handle the content request as shown below.
void handleImagesReply() { if (contentReply->error() == QPlaceReply::NoError) { QMapIterator<int, QPlaceContent> iter(contentReply->content()); while (iter.hasNext()) { qDebug() << "Index: " << iter.key(); QPlaceImage image = iter.value(); qDebug() << image.url(); qDebug() << image.mimeType(); } //alternatively if indexes are irrelevant foreach (const QPlaceImage &image, contentReply->content()) { qDebug() << image.url(); qDebug() << image.mimeType(); } //we can assign content to the place that it belongs to. //the place object serves as a container where we can retrieve //content that has already been fetched place.insertContent(contentReply->request().contentType(), contentReply->content()); place.setTotalContentCount(contentReply->request().contentType(), contentReply->totalCount()); } contentReply->deleteLater(); contentReply = 0; }
It is important to note that the results in the QPlaceContentReply, is a QPlaceContent::Collection which is essentially a QMap<int, QPlaceContent>. The key int
in this case is the index of the content, and the value is the content itself. Due to the way Content is implemented it is possible to convert a content type as follows
QPlaceImage image = content; //provided that 'content' has a type QPlace::ImageType
The usage of the QPlaceContent::Collection and the conversion between content and its subtypes means that code for handling the mechanics of paging reviews, images and editorials can be easily shared.
Search Suggestions
The retrieval of search term suggestions is very similar to performing a place search. A QPlaceSearchRequest is used just like a place search, the only difference being that the search term is set to a partially completed string.
QPlaceSearchRequest request; request.setSearchTerm("piz"); request.setSearchArea(QGeoCircle(QGeoCoordinate(12.34, 56.78))); /* QPlaceSearchSuggestion * */suggestionReply = manager->searchSuggestions(request); connect(suggestionReply, SIGNAL(finished()), this, SLOT(handleSuggestionReply()));
And when the request is done, we can use the reply to show the suggestions.
void handleSuggestionReply() { if (suggestionReply->error() == QPlaceReply::NoError) { foreach (const QString &suggestion, suggestionReply->suggestions()) qDebug() << suggestion; } suggestionReply->deleteLater(); //discard reply suggestionReply = 0; }
Saving a Place
The saving of a new place is performed as follows, we create a QPlace instance and populate it with information such as a name, address and coordinate. Once done we can invoke QPlaceManager::savePlace() to begin a save operation.
QPlace place; place.setName( "Fred's Ice Cream Parlor" ); QGeoLocation location; location.setCoordinate(QGeoCoordinate(12.34, 56.78)); QGeoAddress address; address.setStreet("111 Nother Street"); ... location.setAddress(address); place.setLocation(location); /* QPlaceIdReply * */savePlaceReply = manager->savePlace(place); connect(savePlaceReply, SIGNAL(finished()), this, SLOT(handleSavePlaceReply()));
Once a place is saved the reply contains the new identifier for that place.
void handleSavePlaceReply() { if (savePlaceReply->error() == QPlaceReply::NoError) qDebug() << savePlaceReply->id(); savePlaceReply->deleteLater(); //discard reply savePlaceReply = 0; }
Note that to save an already existing place, the QPlace::placeId() must be filled in with the correct identifier. Otherwise a new place will be created if empty or the wrong place overwritten if the identifier is incorrect.
When a place is saved, the QPlaceManager may emit QPlaceManager::placedAdded() or QPlaceManager::placeUpdated() signals. However whether a manager does so or not is provider specific, managers accessing places from a web service will typically not emit these signals while managers accessing places locally stored generally will.
Caveats
The Places API is currently designed for only saving core details. Saving rich content like images and reviews or details like supplier and rating is not a supported use case. Typically a manager will generally ignore these fields upon save and may produce a warning message if they are populated.
The Places API only supports saving of the following core details:
- name
- place id
- location
- contact details
- icon
- categories (tag-like names to describe a place)
- visibility scope
It is possible that providers may only support a subset of these. See the plugin documentation for more details.
Saving of properties such as the rating, extended attributes, images, reviews, editorials and supplier is explicitly not supported by the Places API.
Saving Between Managers
When saving places between managers, there are a few things to be aware of. Some fields of a place such as the id, categories and icons are manager specific entities for example the categories in one manager may not be recognized in another. Therefore trying to save a place directly from one manager to another is not possible.
The typical approach is to use the QPlaceManager::compatiblePlace() function, it creates a copy of a place, but only copies data that the manager supports. Manager specific data such as the place identifier is not copied over. The new copy is now suitable for saving into the manager. If the manager supports matching by alternative identifiers, an alternative identifier attribute is assigned to the copy (see Matching places between managers)
//result retrieved from a different manager) QPlace place = manager->compatiblePlace(result.place()); saveReply = manager->savePlace(place);
Removing a Place
The removal of a place is performed as follows:
/* QPlaceIdReply * */removePlaceReply = manager->removePlace(place.placeId()); connect(removePlaceReply, SIGNAL(finished()), this, SLOT(handleRemovePlaceReply())); ... ... void handleRemovePlaceReply() { if (removePlaceReply->error() == QPlaceReply::NoError) qDebug() << "Removal of place identified by" << removePlaceReply->id() << "was successful"; removePlaceReply->deleteLater(); //discard reply removePlaceReply = 0; }
When a place is removed, the QPlaceManager may emit the QPlaceManager::placeRemoved() signal. Whether a manager does so is provider specific. Managers accessing places from a web service will typically not emit these signals, while managers accessing places stored locally generally will.
Using Categories
Categories are keywords that can describe a place. For example, 'park', 'theater', 'restaurant'. A place could be described by many categories, it could be a park and a music venue and a ferry or bus stop.
To use categories they must first be initialized.
/* QPlaceReply * */initCatReply = manager->initializeCategories(); connect(initCatReply, SIGNAL(finished()), this, SLOT(handleInitCatReply())); ... ... void handleInitCatReply() { if (initCatReply->error() == QPlaceReply::NoError) qDebug() << "Categories initialized"; else qDebug() << "Failed to initialize categories"; initCatReply->deleteLater(); initCatReply = 0; }
After the categories have been initialized we can then use these category functions.
- QPlaceManager::childCategories()
- QPlaceManager::category()
- QPlaceManager::parentCategoryId()
- QPlaceManager::childCategoryIds();
To retrieve the top level categories we use the QPlaceManager::childCategories() function but do not provide a category identifier.
QList<QPlaceCategory> topLevelCategories = manager->childCategories(); foreach (const QPlaceCategory &category, topLevelCategories) qDebug() << category.name();
If we did provide an identifier then we could retrieve a category's children.
QList<QPlaceCategory> childCategories = manager->childCategories(pizza.categoryId());
Saving a Category
The following shows how to save a category
QPlaceCategory fastFood; QPlaceCategory category; category.setName("pizza"); /*QPlaceIdReply */ saveCategoryReply = manager->saveCategory(category); connect(saveCategoryReply, SIGNAL(finished()), this, SLOT(handleSaveCategoryReply())); //we could have saved a category as a child by supplying a parent identifier. saveCategoryReply = manager->saveCategory(category, fastFood.categoryId()); ... ... void handleSaveCategoryReply() { if (saveCategoryReply->error() == QPlaceReply::NoError) { qDebug() << "Saved category id =" << saveCategoryReply->id(); } saveCategoryReply->deleteLater(); saveCategoryReply = 0; }
When a category is saved, the QPlaceManager may emit QPlaceManager::categoryAdded() or QPlaceManager::categoryUpdated() signals. However whether a manager does so or not is provider specific, managers accessing places from a web service will typically not emit these signals while managers accessing places locally stored generally will.
Removing a Category
Category removal is very similar to removing a place
/* QPlaceIdReply * */removeCategoryReply = manager->removeCategory(place.placeId()); connect(removeCategoryReply, SIGNAL(finished()), this, SLOT(handleRemoveCategoryReply())); ... ... void handleRemoveCategoryReply() { if (removeCategoryReply->error() == QPlaceReply::NoError) qDebug() << "Removal of category identified by" << removeCategoryReply->id() << "was successful"; removeCategoryReply->deleteLater(); //discard reply removeCategoryReply = 0; }
When a category is removed, the QPlaceManager may emit the QPlaceManager::categoryRemoved() signal. Whether a manager does so is provider specific. Managers accessing places from a web service will typically not emit these signals, while managers accessing places stored locally generally will.
Matching Places Between Managers
Sometimes you may want to cross reference whether places from one manager match those from another manager. Such a situation may arise where one manager provides read-only access to places (origin manager) while another second r/w manager (destination manager) is used to save selected favorites from the first. During a search of the origin manager we may want to know which ones have been 'favorited' into the destination manager and perhaps display a customized favorite name rather than the original name.
The matching mechanism can vary between managers, but is typically accomplished through an alternative identifier. As part of the save process, the place identifier from the origin manager is saved as an alternative identifier attribute in the destination manager (which can have its own place identifier scheme). In the following example, the origin manager is from the 'here' QGeoServiceProider, therefore as part of the saving process an alternative identifier attribute, x_id_here, is set for the place saved into the destination manager (when QPlaceManager::compatiblePlace() is called)
origin R/O manager(here) destination R/W manager (places_jsondb) Save Place id: ae246 ---> Place id: 0001 Attribute type: x_provider Attribute type: x_id_here Attribute value: here Attribute text value: ae246
In order to perform the matching, we create a QPlaceMatchRequest and assign it the search results from the origin manager. The QPlaceMatchRequest will be used on the destination manager to return corresponding places. We also specify matching parameters which are key value pairs. As mentioned previously, this can vary depending on the manager but typically the key is QPlaceMatchRequest::AlternativeId to indicate we are matching by alternative id, the value in this case would be x_id_here which specifies which alternative identifier attribute we are using to do the matching.
QPlaceMatchRequest request; request.setResults(results); QVariantMap parameters; parameters.insert(QPlaceMatchRequest::AlternativeId, "x_id_here"); request.setParameters(parameters); matchReply = manager->matchingPlaces(request); ... ... void matchHandler() { if (matchReply->error() == QPlaceReply::NoError) { foreach (const QPlace place, matchReply->places()) { if (place != QPlace()) qDebug() << "Place is a favorite with name" << place.name(); else qDebug() << "Place is not a favorite"; } } matchReply->deleteLater(); matchReply = 0; }

I purchased Adrafinil (Olmifon) from a web site based in South Africa. The cost was about $30, and shipping took about 1 week. The packaging was plain, except for a label stating that the shipment constained 'supplements'. US customs posed no difficulty.
I purchased this rather than Modifinil (Provigil), because of the price, and because purportedly they have the same effect. Adrafinil is said to be harsher on one's liver, but it's still legal in France, so I figured it couldn't be too dangerous to use occasionally.
My hope was that Adrafinil would allow me to be more productive when I was not well rested. Upon first taking it (600 mg), I thought I was slightly more awake, but wasn't sure. Over the follow few weeks I ingested various doses every few days (always between 600 and 1200 mg). During this time I became increasing skeptical that the medication was having any effect on my degree of alertness. If it did, the affect was too minor to have been helpful; certainly it was less powerful than a hearty cup of coffee.
The only effect I am certain this chemical had was to make my urine smell strongly. The smell always subsided after I had stopped taking Adrifinil for a day or two.
In conclusion, I would not recommend Adrifinil, though the only significant side effect of all this was that I wasted a little money.

Today, J Stone delivered his brand new album The Definition Of Loyalty, a consistent batch of west coast flavor; should you be itching for some new music from that particular neck of the woods, it's likely that Stone's latest will be a cure for what ails you. Especially given his association with the late Nipsey Hussle, who went on to lay down some guest vocals alongside Pacman Da Gunman and Casanova. With a g-funk-inspired beat from Bassman providing the foundation, Nipsey sets it off with the hook, his voice immediately tugging at the heartstrings.
At this stage, cries of "The Marathon Continues" have lost their meaning, depending on the source. Yet given that Stone and Nipsey were associates prior to his passing, the dedication feels all the more sincere. Between the three emcees spitting verses, "Nineteen" is a workmanlike approach to a west coast banger; nothing too flashy, but solid all-around. Should you like what you hear, be sure to support J Stone's new album in full right here.

If you want to use Eclipse and WTP (the classic way), please read this docs.
If you intends to run a Maven WAR project, you can adopt m2eclipse-webby, because it will be more efficient. In this case, follow this docs.
Download and install both Apache TomEE (1.7.2 minimum) and Eclipse IDE (not JavaEE version, because Webby doesn't work if m2eclipse-WTP is present).
The next thing you need is m2eclipse plugin. If you doesn't have it in your eclipse package, install it like another plugin.
