With an instance of this class, it is possible to statically and dynamically show a presentation, as defined by the constructor-provided draw model (represented by a sequence of css::drawing::XDrawPage objects). It is possible to show the presentation on multiple views simultaneously (e.g. for a multi-monitor setup). Since this class also relies on user interaction, the corresponding XSlideShowView interface provides means to register some UI event listeners (mostly borrowed from awt::XWindow interface). Since currently (mid 2004), OOo isn't very well suited to multi-threaded rendering, this class relies on <em>very frequent</em> external update() calls, which will render the next frame of animations. This works as follows: after the displaySlide() has been successfully called (which setup and starts an actual slide show), the update() method must be called until it returns false. Effectively, this puts the burden of providing concurrency to the clients of this class, which, as noted above, is currently unavoidable with the current state of affairs (I've actually tried threading here, but failed miserably when using the VCL canvas as the render backend - deadlocked). ******************************************************************************/ typedef cppu::WeakComponentImplHelper<css::lang::XServiceInfo, presentation::XSlide typedef ::std::vector< ::cppcanvas::PolyPolygonSharedPtr> PolyPolygonVector; /// Maps XDrawPage for annotations persistence typedef ::std::map< css::uno::Reference< css::drawing::XDrawPage>, PolyPolygonVector> PolygonMap; class SlideShowImpl : private cppu::BaseMutex, public CursorManager, public MediaFileManager, public SlideShowImplBase { public: explicit SlideShowImpl( uno::Reference<uno::XComponentContext> xContext ); /** Notify that the transition phase of the current slide has ended.
