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.
With this option an array controller driven table view can be sorted by clicking the table column headers without manually setting up sort descriptor prototypes.
If `CPCreatesSortDescriptorBindingOption` is enabled on a table column value binding, sort descriptors will be created automatically. The default value for this option is YES.
Added : -makeViewWithIdentifier:owner:
-rowForView: columnForView: less performant tahn cocoa because we cycle through all visible rows. But these methods are generally used once when editing manually.
Added identifier property to CPView.
retro and forward (in IB) compatible with the existing API. You can use IB table view based without the new API. Existing table views / Nib won't break.
CPTableView view based example. Featuring: IB made data views, different views in the same column, subviews binding in IB
When the view is found automatically in the cib, instantiate with _delegate as the owner (cocoa behavior).
- make every object calling getBinding:forObject: aware of this change
- implement _CPCheckBoxValueBinder to handle binding to the value of a checkbox Closes: #1083
- re-implement CPTextField's behavior for controller markers using the new binder class
- disabled some tests that are not compliant with Cocoa
Don't equality check so the data view is always re-archived when it's set. A dataView with a different font size should be re-archived, but will not be if we check for equality.
All classes (excluding the ones prefixed with underscores) in Foundation
and AppKit can now be loaded individually except CPOpenPanel and
CPSavePanel. These two classes have some sort of dependency cycle
that seems impossible to resolve without forward declarations (which
we don't have).
