Widget that displays any object that implements the GtkTreeModel interface.
Please refer to the tree widget conceptual overview for an overview of all the objects and data types related to the tree widget and how they work together.
Several different coordinate systems are exposed in the GtkTreeView API. These are:
Coordinate systems in GtkTreeView API:
Widget coordinates: Coordinates relative to the widget (usually widget->window
).
Bin window coordinates: Coordinates relative to the window that GtkTreeView renders to.
Tree coordinates: Coordinates relative to the entire scrollable area of GtkTreeView. These coordinates start at (0, 0) for row 0 of the tree.
Several functions are available for converting between the different
coordinate systems. The most common translations are between widget and bin
window coordinates and between bin window and tree coordinates. For the
former you can use gtk_tree_view_convert_widget_to_bin_window_coords()
(and vice versa), for the latter gtk_tree_view_convert_bin_window_to_tree_coords()
(and vice versa).
The GtkTreeView implementation of the GtkBuildable interface accepts GtkTreeViewColumn objects as <child> elements and exposes the internal GtkTreeSelection in UI definitions.
An example of a UI definition fragment with GtkTreeView:

treeview.view ├── header │ ├── <column header> ┊ ┊ │ ╰── <column header> │ ╰── [rubberband] |
GtkTreeView has a main CSS node with name treeview and style class .view. It has a subnode with name header, which is the parent for all the column header widgets' CSS nodes. For rubberband selection, a subnode with name rubberband is used.
gboolean (*GtkTreeViewColumnDropFunc) (GtkTreeView *tree_view
,GtkTreeViewColumn *column
,GtkTreeViewColumn *prev_column
,GtkTreeViewColumn *next_column
,gpointer data
);
Function type for determining whether column
can be dropped in a
particular spot (as determined by prev_column
and next_column
). In
left to right locales, prev_column
is on the left of the potential drop
spot, and next_column
is on the right. In right to left mode, this is
reversed. This function should return TRUE
if the spot is a valid drop
spot. Please note that returning TRUE
does not actually indicate that
the column drop was made, but is meant only to indicate a possible drop
spot to the user.

Since: 2.12
void gtk_tree_view_set_show_expanders (GtkTreeView *tree_view
,gboolean enabled
);
Sets whether to draw and enable expanders and indent child rows in
tree_view
. When disabled there will be no expanders visible in trees
and there will be no way to expand and collapse rows by default. Also
note that hiding the expanders will disable the default indentation. You
can set a custom indentation in this case using
gtk_tree_view_set_level_indentation()
.
This does not have any visible effects for lists.

);
gtk_tree_view_set_rules_hint
has been deprecated since version 3.14 and should not be used in newly-written code.
Sets a hint for the theme to draw even/odd rows in the tree_view
with different colors, also known as "zebra striping".
This function tells the GTK+ theme that the user interface for your application requires users to read across tree rows and associate cells with one another.
Do not use it just because you prefer the appearance of the ruled tree; that’s a question for the theme. Some themes will draw tree rows in alternating colors even when rules are turned off, and users who prefer that appearance all the time can choose those themes. You should call this function only as a semantic hint to the theme engine that your tree makes alternating colors useful from a functional standpoint (since it has lots of columns, generally).

void gtk_tree_view_set_expander_column (GtkTreeView *tree_view
,GtkTreeViewColumn *column
);
Sets the column to draw the expander arrow at. It must be in tree_view
.
If column
is NULL
, then the expander arrow is always at the first
visible column.
If you do not want expander arrow to appear in your tree, set the expander column to a hidden column.
GtkTreeViewColumn *
gtk_tree_view_get_expander_column (GtkTreeView *tree_view

Returns the column that is the current expander column. This column has the expander arrow drawn next to it.
void gtk_tree_view_set_column_drag_function (GtkTreeView *tree_view
,GtkTreeViewColumnDropFunc func
,gpointer user_data
,GDestroyNotify destroy
);
Sets a user function for determining where a column may be dropped when
dragged. This function is called on every column pair in turn at the
beginning of a column drag to determine where a drop can take place. The
arguments passed to func
are: the tree_view
, the GtkTreeViewColumn being
dragged, the two GtkTreeViewColumn s determining the drop spot, and
user_data
. If either of the GtkTreeViewColumn arguments for the drop spot
are NULL
, then they indicate an edge. If func
is set to be NULL
, then
tree_view
reverts to the default behavior of allowing all columns to be
dropped everywhere.

void gtk_tree_view_scroll_to_point (GtkTreeView *tree_view
,gint tree_x
,gint tree_y
);
Scrolls the tree view such that the top-left corner of the visible
area is tree_x
, tree_y
, where tree_x
and tree_y
are specified
in tree coordinates. The tree_view
must be realized before
this function is called. If it isn't, you probably want to be
using gtk_tree_view_scroll_to_cell()
.
If either tree_x
or tree_y
are -1, then that direction isn’t scrolled.
void gtk_tree_view_scroll_to_cell (GtkTreeView *tree_view
,GtkTreePath *path
,GtkTreeViewColumn *column
,gboolean use_align
,gfloat row_align
,gfloat col_align
);
Moves the alignments of tree_view
to the position specified by column
and
path
. If column
is NULL
, then no horizontal scrolling occurs. Likewise,
if path
is NULL
no vertical scrolling occurs. At a minimum, one of column
or path
need to be non-NULL
. row_align
determines where the row is
placed, and col_align
determines where column
is placed. Both are expected
to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means
right/bottom alignment, 0.5 means center.
If use_align
is FALSE
, then the alignment arguments are ignored, and the
tree does the minimum amount of work to scroll the cell onto the screen.
This means that the cell will be scrolled to the edge closest to its current
position. If the cell is currently visible on the screen, nothing is done.
This function only works if the model is set, and path
is a valid row on the
model. If the model changes before the tree_view
is realized, the centered
path will be modified to reflect this change.

void gtk_tree_view_set_cursor (GtkTreeView *tree_view
,GtkTreePath *path
,GtkTreeViewColumn *focus_column
,gboolean start_editing
);
Sets the current keyboard focus to be at path
, and selects it. This is
useful when you want to focus the user’s attention on a particular row. If
focus_column
is not NULL
, then focus is given to the column specified by
it. Additionally, if focus_column
is specified, and start_editing
is
TRUE
, then editing should be started in the specified cell.
This function is often followed by gtk_widget_grab_focus
(tree_view
)
in order to give keyboard focus to the widget. Please note that editing
can only happen when the widget is realized.
If path
is invalid for model
, the current cursor (if any) will be unset
and the function will return without failing.

Sets the current keyboard focus to be at path
, and selects it. This is
useful when you want to focus the user’s attention on a particular row. If
focus_column
is not NULL
, then focus is given to the column specified by
it. If focus_column
and focus_cell
are not NULL
, and focus_column
contains 2 or more editable or activatable cells, then focus is given to
the cell specified by focus_cell
. Additionally, if focus_column
is
specified, and start_editing
is TRUE
, then editing should be started in
the specified cell. This function is often followed by
gtk_widget_grab_focus
(tree_view

the cursor isn’t currently set, then *path
will be NULL
. If no column
currently has focus, then *focus_column
will be NULL
.
The returned GtkTreePath must be freed with gtk_tree_path_free()

Expands the row at path
. This will also expand all parent rows of
path
as necessary.
Since: 2.2
gboolean gtk_tree_view_expand_row (GtkTreeView *tree_view

is expanded in tree_view
.
void gtk_tree_view_set_reorderable (GtkTreeView *tree_view
,gboolean reorderable
);
This function is a convenience function to allow you to reorder
models that support the GtkTreeDragSourceIface and the
GtkTreeDragDestIface. Both GtkTreeStore and GtkListStore support
these. If reorderable
is TRUE
, then the user can reorder the
model by dragging and dropping rows. The developer can listen to
these changes by connecting to the model’s “row-inserted”
and “row-deleted” signals. The reordering is implemented
by setting up the tree view as a drag source and destination.
Therefore, drag and drop can not be used in a reorderable view for any
other purpose.
This function does not give you any degree of control over the order -- any reordering is allowed. If more control is needed, you should probably handle drag and drop manually.
gboolean
gtk_tree_view_get_reorderable (GtkTreeView *tree_view
);
Retrieves whether the user can reorder the tree via drag-and-drop. See
gtk_tree_view_set_reorderable()
.

,gint x
,gint y
,GtkTreePath **path

);
Finds the path at the point (x
, y
), relative to bin_window coordinates
(please see gtk_tree_view_get_bin_window()
).
That is, x
and y
are relative to an events coordinates. x
and y
must
come from an event on the tree_view
only where event->window ==
. It is primarily for
things like popup menus. If gtk_tree_view_get_bin_window()
path
is non-NULL
, then it will be filled
with the GtkTreePath at that point. This path should be freed with
gtk_tree_path_free()
. If column
is non-NULL
, then it will be filled
with the column at that point. cell_x
and cell_y
return the coordinates
relative to the cell background (i.e. the background_area
passed to
gtk_cell_renderer_render()
). This function is only meaningful if
tree_view
is realized. Therefore this function will always return FALSE
if tree_view
is not realized or does not have a model.

Fills the bounding rectangle in bin_window coordinates for the cell at the
row specified by path
and the column specified by column
. If path
is
NULL
, or points to a node not found in the tree, the y
and height
fields of
the rectangle will be filled with 0. If column
is NULL
, the x
and width
fields will be filled with 0. The returned rectangle is equivalent to the
background_area
passed to gtk_cell_renderer_render()
. These background
areas tile to cover the entire bin window. Contrast with the cell_area
,
returned by gtk_tree_view_get_cell_area()
, which returns only the cell
itself, excluding surrounding borders and the tree expander area.

Court rejects Zardari's plea for transfer to Karachi for medical treatment
by Our CorrespondentISLAMABAD: An accountability court on Tuesday rejected former president Asif Ali Zardari’s petition to transfer him to Karachi for medical treatment.
During the hearing, Zardari’s lawyer Sardar Latif Khosa requested the court to shift the former president to Karachi for better medical treatment, adding that Zardari’s entire medical history is in Karachi.
“Zardari had not begged the government earlier, nor will he do so now,” said Latif.
“A petition has been moved in the court for obtaining the legal right.”
The National Accountability Bureau (NAB) prosecutor responded, “requesting the government is not considered begging,” adding that Zardari was shifted to a hospital on the recommendation of a medical board constituted by the government.
The prosecutor continued that the decision to transfer the former president does not fall under the jurisdiction of the court, adding that the hospital has been declared a sub-jail for the former president.
He further said that Zardari should submit an application to the government if a private doctor was needed.
Zardari was moved to Pims from Adiala jail on October 22. He was admitted to the cardiology department where he underwent a number of tests and was declared to be out of danger.
Mega money laundering case
The court extended the judicial remand of former president Asif Ali Zardari and Faryal Talpur in the mega money laundering case.
The accused are to appear before the court on November 26.
Judge Azam Khan of the accountability court issued the order.

DWhite (pronounced like the name Dwight) is an API for synchronizing trees or graphs of nodes. Although the name is inspired by distributed whiteboards (a GUI application), DWhite actually supports any type of tree or graph of data.
DWhite adopts a very simple "Model, View, Controller (MVC)" API. The core of DWhite allows a client to synchronize it's local copy of a "Model" (tree or graph) with the server's version of the same tree. "Views" and "Controllers" are applications, logically seperate from the DWhite core, that can query and manipulate the Model. Client copies of the Model can be partially or fully populated. The logical view of DWhite and an application on top of it, showing the major flows of data, looks like this:
[wish somebody'd whip me up a PNG and/or SVG of this <wink>] +----------------------------------------+ | Application | Client: +-------------+-------------+------------+ | View | ^ | Controller | +-------------+ | +------------+ ^ | | | | | message / / / layer / / / | | | | | v +-------------+ | +------------+ | View | | | Controller | Server: +-------------+-------------+------------+ | Model | +----------------------------------------+
The Model of all applications are trees or graphs of nodes. Nodes may be major nodes or minor nodes. Major nodes are the primary nodes of information in DWhite and may contain many properties, minor subnodes, and major subnodes. Major nodes may be copied fully or partially. Minor nodes may contain many properties, minor subnodes, and major subnodes, but are always copied in full as part of their containing major node. Every major node in DWhite has at least the following properties:
DW:Id The DWhite ID of this node. DW:Signature The DWhite signature of this node. DW:Partial If present, indicates that this is a partial copy.
A DW:Id uniquely identifies a node within one tree of an application and never changes and is never reused as long as the tree exists. A DW:Id will always refer to the same node regardless of where it is moved in the tree. A DW:Signature (based on XSignature) records the state of a node at one point in time and is used to check whether or not a node has been updated. DW:Partial indicates whether the node is fully populated (DW:Partial is false or undefined) or partially populated (DW:Partial is true). A partially populated major node always contains a DW:Id, a DW:Signature, and DW:Partial indicator, and MAY contain additional properties as defined by an application.
Minor nodes do not have DW:Id's, DW:Signatures's or DW:Partial indicators, and are always fully populated.The core DWhite API has only two methods, getNode() and checkNode(). An empty string ("") as a DW:Id always represents the root node of a tree, it is used as a starting point for building the client copy of the tree. The returned root node may have a DW:Id that contains a real (not "") identifier. Application View APIs will also have methods that will return specific (usually partial) nodes within the tree.

Until now I have been using a 220Ω resistor to convert the current signal to voltage, but since the Arduino UNO has an operating voltage of 5V I calculated the appropriate resistor to use the entire range, to do so I used the maximum current of the sensor(20mA).
\[R = {5V \over 0.02A} = 250Ω .\]
Knowing this, the circuit was changed to include a resistor of 250Ω .
Once again the entire process of gathering some analyses was redone and the next curve was acquired with the respective equation.
The Arduino UNO has analogue inputs of 10 bits which allows a resolution of 1024 values, and since the sensor was limited to a minimum of 100mm and a maximum of 500mm each value will represente a variation of 0.4mm. Having this in mind the new circuit was tested and the results where satisfactory once again. However, the readings did not improved because they continue to oscillate between two values with a diference of 0.57mm. For example when measuring 250mm with the sensor the Arduino readings changed between the values of 250.21mm and 250.78mm. This can be explained whit the fact that the sensor has a resolution analog output of 12 bits losing this way 2 bits when entering the Arduino.
CalibrationThe calibration of the laser sensor was carried on with the determination of the transformation from the coordinate system of the tip of the gripper to the coordinate system of the sender of the laser. The process of determining if the angle of the sensor changes with the perpendicular movement of the robot's end effector was redone with more precision. When moving the end effector 518.39mm the laser moved 5.5mm, this represents that the laser shifts 0.6 degrees when it moves from 64mm to 580mm in relation to the table. This offset is less than 1 degree so it's not going to be taken into account, at least for now. Afterwards the translation of the X,Y and Z was calculated. To calculate the exact diference from the tip of the gripper to the laser in the Z axis I gathered some readings from the laser when it is vertically pointing to the table, thus knowing the difference to the base of the robot. Then those where compared with the z-coordinate of the end effector read in the RVIZ. After gathering data for different distances the average was calculated, hence having a 63.6mm diference from the sender of the laser to the tip of the gripper. In order to calculate the translation in the X and Y directions the gripper was replaced by a pencil and the difference to the laser beam was evaluated.
In the picture below it is possible to see that there is a difference of 47.8mm and 16.6mm in the X and Y direction, respectively.
Having already the transformation the URDF was changed, by altering the binpicking_robot_macro.xacro file and adding the binpicking_gripper_macro.xacro, in order to incorporate the coordinate system of the sender of the laser sensor. The STL of the device was also included for a better visualization.
The calibration of the Kinect was my next step this week. To do so the visp_hand2eye_calibration ROS package was used. This package is used to estimate the camera position with respect to its effector (the robot arm) using the ViSP library. To compute the relative transformation between the the camera and the hand it is necessary to fed the calibrator node with the /world_effector and the /camera_object transformations. This last one is calculated using an aruco and the aruco_detect package which detects the pose of aruco markers, and this process can be visualized in the picture below.
To use this package it is necessary to install the fiducial software from binary packages using the following command.
sudo apt-get install ros-kinetic-fiducials
This calibration process is easily visualized in the scheme bellow.
For this calibration to work, the creation of a client, which feeds different transformations to the calibrator responsible for computing the relative transformation between the the camera and the hand from a few poses, is fundamental. The camera_calibration_client.py program, present in the calibration file, is responsible for executing this process and printing the /effector_camera transformation in the xyz(transformation) and rpy(rotation) format. With this it is possible to visualize the tree of the transformations of the entire system.
In order to visualize the robot, the Kinect, the laser sensor and all the associated coordinate systems, the URDF model of the entire system was changed, by altering the binpicking_macro.xacro file to incorporate the Kinect. All the components can be visualized and analysed live by running the next command.

While using the RobComm language to send commands to move the robot, I observed that the origin in the base_link differs from the one visualized in RVIZ with the URDF of the FANUC robot. Besides the X and Y coordinate being almost the same, the Z-coordinate has a gap of 162.5mm. Hence, when moving the robot to a desired point I will have to take this aspect into consideration, when using the RobComm language.

KidsX has partnered with the City of Glendale, CHLA, Microsoft, and verynice on a 3-day design-a-thon challenge to come up with innovative and creative approaches to addressing the issues surrounding food insecurity, which impacts more than 1.2M homes in LA County.
Food insecurity (temporary, situational or ongoing) is having a lack of consistent, reliable access to enough healthful foods to meet the needs of everyone in a household to support a healthy lifestyle
A hyper-personalized SMS mobile platform that can help guide food insecure families through the process from picking up free/reduced groceries at convenient Amazon Hub locations to cooking personalized meals.
Our solution addresses pain points for 3 parties: patients(people who are food insecurity), managers of solutions, and supply chain/distribution parties. So here’s the user journey.

FROM MR kanazoe alidaa.
BILL AND EXCHANGE MANAGER
FOREIGN REMITTANCE DEPT.
BANK OF AFRICA (B.O.A)
OUAGADOUGOU,BURKINA FASO
Dear,
I am the manager of bill and exchange at the foriegn remittance department
of Bank Of Africa (B.O.A). In my department we discovered an abandoned sum
of US$15.5 (fiftteen million five hundred thousand US dolloars) in an account that
belongs to one of our foriegn customer who died along with his entire family in a
plane crash that happened in Kenya, East Africa.
Since we got information about his death, we have been expecting his next
of kin to come over and claim his money because we cannot release it unless
some body applies for it as next of kin or relation to the deceased as
indicated in our banking guidlines and laws but unfortunately we learnt that
all his supposed next of kin or relation died alongside with him at the
plane crash leaving nobody behind for the claim.
Please I want you to visit the website below for more information about the
Plane Crash and the Deceased DR. GEORGE W. BRUMLEY AND HIS
FAMILY: http://www.cnn.com/2003/WORLD/africa/07/20/kenya.crash/index.html
It is therefore upon this discovery that I now decided to make this business
proposal to you and release the money to you as the next of kin or relation
to the deceased for safety and subsequent disbursement since nobody is
coming for it and I don't want this money to go into the bank treasury as
unclaimed bill.
I agree that 40% of this money will be for you as a foreign partner, in
respect to the provision of a foriegn account, and 60% would be for me,
There after I will visit your country for disbursement according to the
percentage indicated.
Therefore, to enable the immediate transfer of this fund to you as
arranged,youmust apply first to the bank as relation or next of kin of the
deceasedindicatingyour bank name, your bank account number, your private
telephone andfax number for easy and effective communication and location
wherein the money will beremitted.Upon the receipt of your reply,
I will send to you by fax or email the text of the application to fill and
send to the bank. I will not fail to bring to your notice that this
transaction is 100% Risk free and you should keep this transaction top secret.
I know what to do and move the fund into your account without any delay and
that you should not entertain any atom of fear as all required arrangements
have been made for the transfer.
You should contact me as soon as you receive this letter .
Yours faithfully.
Mr kanazoe alidaa.

The avicap32.dll contains functions for connecting to and listing available video capture device on your system.
First load a list of available video capture devices into a listbox. To do this, use a loop that checks to see if there is a driver available. If there is, add it to a listbox.
To display the output from a video capture device, you need to create a capture window, connect to the device, scale the output to fit the window, set the preview rate, and finally tell it to start previewing. Create a child window with capCreateCaptureWindowA so you can display it in a picturebox.
To retrieve an image from the preview window, use SendMessage to copy the data to the clipboard. Then transfer the image to the picture box.
Finally, to close the preview window, disconnect from the device and destroy the preview window.
See the code for details.

Boost.Build makes it easy to build C++ projects, everywhere.
You name you executables and libraries and list their sources. Boost.Build takes care about compiling your sources with right options, creating static and shared libraries, making executables, and other chores — whether you're using gcc, msvc, or a dozen more supported C++ compilers — on Windows, OSX, Linux and commercial UNIX systems.
Simple and high level build description. In most cases a name of target and list of sources is all you need.
Portability. Most important build properties have symbolic names that work everywhere. Why memorize compiler flags necessary for multi-threaded 64-bit shared library, if Boost.Build can do it for you?
Variant builds. When you build the same project twice with different properties, all produced files are placed in different directories, so you can build with 2 versions of gcc, or both debug and release variants in one invocation.
Global dependencies. No matter what directory you build in, Boost.Build will always check all dependencies in your entire project, preventing inconsistent binaries. And it's easy to use one Boost.Build project in other, again with full dependency tracking.
Usage requirements. A target can specify properties, like include paths and preprocessor defines, that are necessary to use it. Those properties will be automatically applied whenever the target is used.
Standalone. Boost.Build's only dependency is a C compiler, so it's easy to setup. You can even include all of Boost.Build in your project. Boost.Build does not depend on Boost C++ Libraries.

Kane spent hours with Pochettino after manager's Spurs sacking
by BeSoccerHarry Kane and Mauricio Pochettino met after the 47-year-old was sacked as Tottenham manager.
Harry Kane revealed he spent "a couple of hours" with Mauricio Pochettino in the wake of the Argentinian's sacking as Tottenham manager.
Pochettino was sacked on Tuesday and replaced by Jose Mourinho, who guided Spurs to a 3-2 win at West Ham in his first game in charge.
Kane, who scored at the London Stadium, visited Pochettino the day after the 47-year-old was sacked.
"I've been to see him," the star forward told UK newspapers.
"I went around his house and caught up with him the next day. It was a shock for everyone, so I wanted to go and see him and we had a chat for a couple of hours, and it was nice to do that before the new manager came in.
"It's been a week I've never really had in my career before. A big shock on Tuesday night for everyone, the players included. And then it was a quick turnaround all of a sudden we got a new manager, one of the best managers there has been in the game."

While Pochettino impressed at the helm of Tottenham, including reaching last season's Champions League final, he failed to deliver a trophy.
Mourinho is a serial winner and Kane hopes the Portuguese tactician can lead Spurs to the trophies he craves.
"The gaffer has won every club he has gone to, there's no hiding away from that," he said.
"He wants to win, he's a proven winner. I've made it clear that I'm at the stage of my career where I want to win trophies, I've made it clear I want to win them here and it's a big year for this.
"Realistically, we look at the Champions League and the FA Cup to try to do that. We will see how that goes and, from my point of view, I will keep doing what I'm doing and keep fighting for this club on the pitch."
Spurs host Olympiacos in the Champions League on Tuesday as they look to book their place in the knockout stage.


Once banks determine how likely you are to repay a loan, they can make a decision about whether they will loan you money, whether that's as a student loan, credit card, or something else. They use the credit score to determine the amount of money they can expect to make off of the loan. If you don't repay the loan, they will lose all of the money that they loaned you. If you do repay the loan, then they make money - in the form of the interest that you pay back on the loan. This is called the expected value of the loan. It depends on both the probability that a borrower will pay back the loan, the amount of money being borrowed, and the amount of interest that the bank will make off of the loan.
