2005-07-07 22:02 Gregory John Casamento <greg_casamento@yahoo.com>
* GormCore/GormCustomClassInspector.m: In the method
- (void) _replaceCellClassForObject:className: added logic to
automatically replace the cell in a more generic fashion.
* GormCore/GormPrivate.m: Added logic to canSubstituteForClass: to
determine if it's possible for the class passed in to substitute for
the reciever.
* Palettes/2Controls/inspectors.m: Removed canSubstituteForClass:
implementation for NSSecureTextView.
* Palettes/3Containers/GormNSOutlineView.[hm]: Cleaned up
initWithCoder: and encodeWithCoder:.
* Palettes/3Containers/GormNSTableView.[hm]: Ditto
2005-07-07 13:22 Gregory John Casamento <greg_casamento@yahoo.com>
* GormCore/GormControlEditor.m: Removed commented out code
