+
+ SlideShowImpl
+
+ This class encapsulates the slideshow presentation viewer.
+
+ 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).
