2007/03/11 00:17:58 thb 1.1.2.3: #i37778# Necessary adaptions for cppcanvas clip behaviour (extra setClip() methods to clear clip, instead of empty polygon, which denotes everything clipped on canvas); removed cyclic references for intrinsically animated shapes (GIF and drawing layer scroll text); fixed a few coding style inconsistencies 2007/01/29 16:29:29 thb 1.1.2.2: #i37778# Build fixes for msvc; added shapes lib to util link line 2007/01/29 14:02:05 thb 1.1.2.1: Issue number: #i37778# Larger slideshow refactoring. Wrote design and coding style manifest, and adapted the code to actually conform to this. In detail: - cleaned up ownership/disposable/weak_ptr story. removed hacks and explicit Disposable implementations, where workaround were available - removed object mutices, where superfluous - reworked EventMultiplexer (using templatized listener class now), added more events. EventMultiplexer now serves as a true blackboard - reworked directory structure: disjunct parts are now physically separated into directories, instantiation happens via factories & abstract interfaces - added CursorManager, to make setting mouse cursor less hackish - reworked DrawShape, to implement SeparateListener pattern - reworked IntrinsicAnimationActivity, to avoid cyclic references - modified hyperlink & shape cursor handling to communicate via EventMultiplexer - renamed & cleaned up files (presentation.cxx now named slideshowimpl.cxx, etc.) - added first version of the z-order fix to layer/layermanager - cleaned up include guards and include syntax
