Previously, CPImageView would sometimes attach a notification to CPImageDidLoadNotification when the image was set, but would never remove this notification. The view could then leak memory as the notification center would be keeping a reference even if the view was no longer being used.
This commit fixes that issue by removing the observation once the image has loaded.
Fixes#2198.
Previously, _createDOMImageElement was not called until after [super initWithCoder] was called. But that call would end up in CPImageView -setObjectValue, which would attempt to access _DOMImageElement before it had been created.
Now _DOMImageElement is checked before being accessed or created.
Tagging with UIDs can make it much easier to debug encoding/decoding related bugs where it's not clear that the right view ended up in the right spot.
The new data attribute is called "data-cappuccino-uid".
Also collect and simplify appkit_tag_dom_elements code a little.
Without this fix, the `appkit_tag_dom_elements` flag would only affect CPImageViews unarchived from a coder (e.g. in a collection view, from a cib). It would have no effect on a CPImageView created in code.
This change refactors the _DOMImageElement code to a shared method, reducing redundancy while fixing the bug.
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.
- CPView and subclasses support multiple-value hidden bindings.
- CPControl and subclasses support multiple-value enabled bindings.
- CPWindow and CPBox support multiple-value title with pattern bindings.
- CPButton supports multiple argument + target bindings.
- CPImageView and CPTextField support multiple-value editable bindings.
- CPMenuItem supports multiple-value enabled bindings.
- Fixed bugs in CPObjectController with simple collection operators.
- CPColorWell uses black as the placeholder color.
- Runtime object attributes from a cib are applied as they are read, not deferred.
- NSNumberFormatter now reads the number style from the xib.
- Normalized some parameter names.
- Formatting.
- Test app for all binding types.
- Changed from deprecated image scaling constants to new ones.
- Added support for CPImageScaleProportionallyUpOrDown (thanks BlairDuncan).
- Cleaned up image layout code.
