The following @button nodes allow me to watch movies in the body pane!
The only problem is that the act of creating the phonon.VideoPlayer
causes Leo to crash on exit. Presumably it's a bug in phonon :-)
To use, create an @movie node with the filename in the body. Hit the
load-video button. Hit the play/pause button to pause and resume.
Hit the stop button to stop the video and show the body pane. Works
with music too.
@button load-video
