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<presentation::XSlideShow> SlideShowImplBase; + +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> const& xContext ); + + /** Notify that the transition phase of the current slide + has ended. + + The life of a slide has three phases: the transition + phase, when the previous slide vanishes, and the + current slide becomes visible, the shape animation + phase, when shape effects are running, and the phase + after the last shape animation has ended, but before + the next slide transition starts. + + This method notifies the end of the first phase. + + @param bPaintSlide + When true, Slide::show() is passed a true as well, denoting + explicit paint of slide content.
