A foreign resource that wants to be shared between several SICStus run-times must somehow know which SICStus run-time is calling it so that it can make callbacks using the SICStus API into the right SICStus run-time. In addition, the foreign resource may have global variables that should have different values depending on which SICStus run-time is calling the foreign resource.
A header file is generated by splfr when it builds a
foreign resource (before any C code is compiled). This header file
provides prototypes for any foreign
-declared function, but it
also provides other things needed for multiple SICStus run-time
support. This header file must be included by any C file that contains
code that either calls any SICStus API function or that contains any of
the functions called by SICStus. See The Foreign Resource Linker.


MKMenuView Class Reference
| Inherits from | MKView : UIView |
| Declared in | MKMenuView.h |
Overview
The MKMenuView object displays a popup holding MKMenuItem control objects. The view's frame will be automatically set using the number of MKMenuItems passed to it. MKMenuView can hold up to 6 different icons.
MKMenuView listens for the MK_MENU_VIEW_SHOULD_REMOVE_NOTIFICATION
to remove itself. If you use the showWithAnimationType: method to display the view, you should post this notification to remove it.
Tasks
Creating Instances
-
- initWithItems:
Returns an intialized instance of MKMenuView. This instance will be sized by the number ofitems
provided. Instances of MKMenuItem will be placed in the order that are given.
Properties
-
items
The array MKMenuItems that are placed onto the view.
Instance Methods
initWithItems:
Returns an intialized instance of MKMenuView. This instance will be sized by the number of items
provided. Instances of MKMenuItem will be placed in the order that are given.
- (id)initWithItems:(NSArray *)items
Parameters
- items
- an array of MKMenuItems to be placed onto the menu.
Exceptions
- itemsCount
- raises an exception if more than 6 items are given.

HW5, practice material from the “Whirlwind Tour of Python”¶
The material covered in lectures 8 and 9 will primarily be practiced as you work on your individual project.
Thus, this homework is a little different from the others. It is based on sections 8-13 of https://jakevdp.github.io/WhirlwindTourOfPython/index.html. Knowing this material will help you with Python programming in general, and your project in particular.
The question numbers start with 8 so that the numbers align with the section of the book. Thus, it points to which section to read if you do not already know how to answer the question.
8. Control Flow Statements¶
i. Write your own working if-elif-else statement¶
In [ ]:
ii. What does the break
statement do?¶
iii. Write your own for
loop that includes a break
statement, that causes some output to be different than if the break
were not included. Verify that output.¶
In [ ]:
iv. What does the continue
statement do?¶
v. Write your own while
loop that includes a continue
statement. Check that the statement did what was expected.¶
In [ ]:
9. Defining Functions¶
Define a function (which has not been used in an example in class or in the Whirlwind book) that has at least one required and one optional parameter, and then call it.
Suggestion: Write this answer with the next question in mind. In the next question you’ll need some code that sometimes works, and sometimes has an error. If this is true of what you write here, you can use the same function and then update it to catch the error when you answer the next question.
In [ ]:
10. Errors and Exceptions¶
Write a function that sometimes will work and sometimes will not (this can be your answer to the previous problem). Add a try-catch (try…except) clause so you get a nice, clean error message instead of a runtime error.
In [ ]:
11. Iterators¶
- Write a function using the
enumerate
iterator.
In [ ]:
- Write a function using the
zip
iterator.
In [ ]:
12. List Comprehensions¶
Is the following a valid line of Python code? If so, what is the output? If not, fix what is wrong and then list the output. ~~[val for val in range(20) if val % 3 = 0]~~
In [ ]:
13. Generators and Generator Expressions¶
What is the difference between the following two snippets of code?
P = (n ** 2 for n in range(12))
for val in P:
print(val, end=' ')
Q = [n ** 2 for n in range(12)]
for val in Q:
print(val, end=' ')

Namespace EventHook
Classes
ApplicationEventArgs
An event argument object send to user.
ApplicationWatcher
A wrapper around shell hook to hook application window change events. Uses a producer-consumer pattern to improve performance and to avoid operating system forcing unhook on delayed user callbacks.
ClipboardEventArgs
An argument send to user.
ClipboardWatcher
Wraps around clipboardHook. Uses a producer-consumer pattern to improve performance and to avoid operating system forcing unhook on delayed user callbacks.
EventHookFactory
A factory class core to the management of various watchers that all shares the same synchronization objects. Use this class to get instances of differant watchers. This factory instance should be disposed only after all watchers it have been unsubscribed.
KeyboardWatcher
Wraps low level keyboard hook. Uses a producer-consumer pattern to improve performance and to avoid operating system forcing unhook on delayed user callbacks.
KeyData
Key data.
KeyInputEventArgs
Key press data.
MouseEventArgs
Event argument to pass data through user callbacks.
MouseWatcher
Wraps low level mouse hook. Uses a producer-consumer pattern to improve performance and to avoid operating system forcing unhook on delayed user callbacks.
PrintEventArgs
An argument passed along user call backs.
PrintEventData
An object holding key information on a particular print event.
PrintWatcher
A class that wraps around printServer object.
WindowData
An object that holds information on application event.
Enums
ApplicationEvents
An enum for the type of application event.
ClipboardContentTypes
Type of clipboard content.
KeyEvent
Key press event type.
