Previously, Cappuccino was using preprocessor macros internally for the CGPoint/Size/Rect/Inset/Affine functions, as well as for CPRange. These macros had the same name as the corresponding function, but began with _. The functions were actually defined using the macros.
The motivation behind using macros was to increase performance by reducing function calls. However, there were a number of problems with this approach:
- There was an artificial dichotomy between _CG macros and the corresponding CG functions. We never completely replaced CG function calls with _CG macros. In fact, they were often mixed up in the same file. There was an extra burden on the programmer to remember to use the macro instead of the function.
- If a method call was passed as an argument to a macro, performance could actually be significantly *worse* than a function call. For example, _CGGetRectMakeCopy([view frame]) would expand to `{ origin:{ x:[view frame].origin.x, y:[view frame].origin.y }, size:{ width:[view frame].size.width, height:[view frame].size.height } }`. So instead of a single objj_msgSend and a single simple function call, we ended up with 4 objj_msgSend calls, which are way more expensive than simple function calls.
- Because of this expansion problem, to use macros efficiently required us to remember to use variables for all macro parameters. This didn't happen, and shouldn't have to happen.
- Finally, with modern Javascript engines, function call overhead is so small that it really isn't worth using the macros.
This commit eliminates the _CGGeometry, CGAffineTransformation and CPRange macros and replaces them with function calls.
BREAKING CHANGE:
The macros are no longer available. They could only be used with compiled code, but if there is any user code that used them, they will have to be replaced with the corresponding functions.
- Fixed case where a dangling transition function was left when closing a popover.
- Fixed case where closing a popover, moving the target view, then reopening the same popover would not reposition the popover when resizing the target view's window.
- Optimized repositioning of popover on target view change.
- Implemented transitional popovers via trapped mouse down events.
- Implemented dequeue: argument of CPApplication -setTarget:selector:forNextEventMatchingMask:untilDate:inMode:dequeue: and -setCallback:forNextEventMatchingMask:untilDate:inMode:dequeue:.
- Fixed some child window behavior when ordering/closing.
- Eliminated no longer necessary window close notification in CPPopover.
- Fixed window title in theme so it doesn't dim when window is main but not key.
- Changed from deprecated image scaling constants to new ones.
- Added support for CPImageScaleProportionallyUpOrDown (thanks BlairDuncan).
- Cleaned up image layout code.
If a segmented control was initialised with a zero width and then expanded with setSegmentCount, it would not allocate space for any needed dividers. The more tabs were added the more the segmented control would be undersized. The fix is to automatically adjust the width when dividers are added or removed.
Closes#386.
Also fixes the error where right side of segments would often not be visible.
Also fixes the error which caused the right and left bezel images to not show as disabled ever.
