178 : This class encapsulates the slideshow presentation viewer.
179 :
180 : With an instance of this class, it is possible to statically
181 : and dynamically show a presentation, as defined by the
182 : constructor-provided draw model (represented by a sequence
183 : of ::com::sun::star::drawing::XDrawPage objects).
184 :
185 : It is possible to show the presentation on multiple views
186 : simultaneously (e.g. for a multi-monitor setup). Since this
187 : class also relies on user interaction, the corresponding
188 : XSlideShowView interface provides means to register some UI
189 : event listeners (mostly borrowed from awt::XWindow interface).
190 :
191 : Since currently (mid 2004), OOo isn't very well suited to
192 : multi-threaded rendering, this class relies on <em>very
193 : frequent</em> external update() calls, which will render the
194 : next frame of animations. This works as follows: after the
195 : displaySlide() has been successfully called (which setup and
196 : starts an actual slide show), the update() method must be
197 : called until it returns false.
198 : Effectively, this puts the burden of providing
199 : concurrency to the clients of this class, which, as noted
200 : above, is currently unavoidable with the current state of
201 : affairs (I've actually tried threading here, but failed
202 : miserably when using the VCL canvas as the render backend -
203 : deadlocked).
