190 SlideShowImpl
191
192 This class encapsulates the slideshow presentation viewer.
193
194 With an instance of this class, it is possible to statically
195 and dynamically show a presentation, as defined by the
196 constructor-provided draw model (represented by a sequence
197 of ::com::sun::star::drawing::XDrawPage objects).
198
199 It is possible to show the presentation on multiple views
200 simultaneously (e.g. for a multi-monitor setup). Since this
201 class also relies on user interaction, the corresponding
202 XSlideShowView interface provides means to register some UI
203 event listeners (mostly borrowed from awt::XWindow interface).
204
205 Since currently (mid 2004), AOO isn't very well suited to
206 multi-threaded rendering, this class relies on <em>very
207 frequent</em> external update() calls, which will render the
208 next frame of animations. This works as follows: after the
209 displaySlide() has been successfully called (which setup and
210 starts an actual slide show), the update() method must be
211 called until it returns false.
212 Effectively, this puts the burden of providing
213 concurrency to the clients of this class, which, as noted
214 above, is currently unavoidable with the current state of
215 affairs (I've actually tried threading here, but failed
216 miserably when using the VCL canvas as the render backend -
217 deadlocked).
