CPOutlineView.j used CPTreeNode before AppKit.j imported it. This
triggered build warnings. This commit adds an import.
- Add @import "CPTreeNode.j" to CPOutlineView.j.
While addressing this warning, CPTreeNode was audited and found to have an algorithmic complexity regression and multiple structural inconsistencies in the KVO support code.
The test suite for CPTreeNode was Spartan in the extreme.
All of these have been addressed - see inline notes for details.
CPTreeNode is subject to further audit.
In some places the objj_msgSend function is called directly. Most of the times the old slower version is called. This commit will use the never faster version instead.
Previously, when reloading the CPOutlineView and changing an item to another parentItem, the CPOutlineView deleted the reference of the item.
Now, when removing old data to avoid memory leaks, the CPOutlineView checks if the pending item to delete doesn't have another parent item.
Previously, when reloading a CPOutlineView with different datas than before, the CPOutlineView kept a reference of the previous datas.
Now, when reloading, the CPOutlineView will delete these references when we don't need it anymore. For that, the CPOutlineView will only try to delete the previous reference when we have reloaded the children of a node, otherwise it will keep the other references.
This PR fix some issue with the following methods :
- (BOOL)isExpandable:(id)anItem;
- (BOOL)isItemExpanded:(id)anItem;
- (CPInteger)rowForItem:(id)anItem;
- (CPInteger)levelForItem:(id)anItem;
- (id)itemAtRow:(CPInteger)aRow;
- (CPInteger)levelForItem:(id)anItem;
- (CPInteger)levelForRow:(CPInteger)aRow;
Previously these methods took care about not displayed items. Now they just work with displayed items.
Added unit-tests in Test/AppKit/CPOutlineViewTest.j
Test app in Test/Manual/CPOutlineViewTestCib
