2007/03/11 01:01:09 thb 1.1.2.3: #i37778# Made wait shape to update screen immediately, as it's otherwise invisible because of not staying past main animation loop commitScreenUpdates() 2007/01/30 16:43:51 thb 1.1.2.2: #i37778# Made view update/repaint/resize work again; swapped BackgroundShape parameters for correct mtf import 2007/01/29 14:02:26 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
