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.
Previously, when a sheet was resized, there were a number of problems:
- Sheets in Cocoa resize their width symmetrically, such that they always remain centered. This was not happening in Cappuccino.
- When a sheet is resized wider than its parent window, the shadow at the top of the sheet was growing wider than the bounds of the parent window's title bar, which makes no sense since the shadow is supposed to be cast by the title bar.
- Sheets had no top border, so when they were resized wider than the parent window, the top edge looked like it was cut off. In Cocoa, sheets have a top border that sits under the title bar of the parent window, and which is visible when the sheet is resized wider than the parent window.
This commit addresses these problems as follows:
- Sheet width is now resized symmetrically.
- Sheet resizing is pinned to the screen bounds.
- The top sheet shadow is pinned to the width of the parent window's content view.
- Sheets now have a top border.
In addition to these changes, a redundant sheet top shadow was eliminated from one of the _CPWindowView subclasses.
Fixes#1846
Previously sheet animation was performed by sizing the sheet from zero to full height when animating in, and then back to zero height when animating out. This caused problems with the resize algorithms, which are not designed to deal with sizing from zero.
Analyzing Cocoa behavior revealed that sheets slide in and out with no resizing.
With this commit, a general purpose mechanism for clipping a window to a rect was added to CPDOMWindowLayer. Clipping was put in CPDOMWindowLayer because that is the class that deals with windows at the global level. CPWindow uses the clipping mechanism to slide the sheet in and out, thus avoiding all resizing problems.
Fixes#1840
Without this fix all regular key events such as `CPKeyDown` would have an undefined location.
Since the location can't be retrieved from the browser on key events, this fix now makes it so that the last seen mouse position is included with each key event.
- Added CPWindow -_parentWindowDidOrderInChild to notify a window when it is directly ordered in by a parent.
- Fixed observing of target view frame changes to work in all possible cases.
- Fixed typo in code introduced in last commit in CPApplication -sendEvent.
- Popovers are implemented as child windows.
- Renamed _CPAttachedWindow/_CPAttachedWindowView to _CPPopoverWindow/_CPPopoverWindowView, since that is its only use.
- The default for CPView -acceptsFirstMouse is now NO, per Cocoa. Subclasses override this as necessary.
- _CPWindowView -hitTest returns self it the mouse is within a resize region, which may be outside the window's frame.
- Fixed an off by one bug in CPDomWindowLayer -insertWindow:atIndex:, where inserting a visible window behind a window it is already behind would cause it to move up one from its intended position.
- Updated the ChildWindows and CPPopover test apps.
- Track mouse exit from window resize rect instead of unconditionally setting arrow cursor.
- Don't show the resize cursors for full platform windows.
- Show the resize down cursor if the top of a window is being resized and it has reached the bottom of the menubar.
- Make windows in CPToolbarTest resizable to test resizing behavior with toolbars.
- Added a full platform window and menubar to the test app.
`CPEvent timestamp` is now in seconds so the double click delay has to be adjusted. Also slightly increased double click interval to account for lower precision.
If a custom font was used with the CSS @font-face syntax, Cappuccino would calculate the wrong sizes for strings throughout. This could result in e.g. cut off sizeToFit labels.
The sizing tests were being performed inside of an iframe and that iframe would not have the same CSS @font-face declarations. For maximum fidelity all string size tests are now performed in the main document, just off screen.
- System fonts now track the currently configured system font at runtime.
- You can specify CPFontCurrentSystemSize as a system font size to track the currently configured system font size at runtime.
- Theme fonts and nib2cib now determine face and size at runtime, there is no need to recompile if the system font is changed in Info.plist.
- All hard-coded references to 12.0 as a system font size have been replaced by the current system font size.
- Moved common CPArray/CPSet collection KVC operators to _CPCollectionKVCOperators.
- Implemented KVC operator dispatch using Objective-J.
- Fixed infinite loop with empty collection in @min, @max and @sum operators.
- Correctly return valueForUndefinedKey when necessary.
- valueForUndefinedKey reason uses raw description for consistency, class' overridden description may not helpful at all.
- Don't create a forwarder for @ operators with property paths.
- Fixed CPSet -valueForKeyPath to correctly deal with nil/undefined/empty values.
- Added tests for collection KVC operators.
- enumerator -nextObject should always compare against nil for clarity, correctness, and consistency.
if setTitle: is called on a CPWindow with the primaryPlatformWindow as platformWindow,
the main page's title is changed. This patch prevent changing the primaryPlatformWindow's title.
This is not optimal, but this is better than changing the title at each window setTitle: call
