The VideoLAN Forums

hi
i'm trying to use jvlc and i have some problems with the mouse listener which is lied to the canvas (lied to mediaPlayerFactory VLC works with)
if i don't launch the video with the line "mediaPlayer.play();", the mouse listener works fine.
as soon as the line "mediaPlayer.play();" is read, the mouse listener is disabled
something strange happens: when the video is launched, some events are detected even if i don't touch the mouse (i launch the program with a keyboard shortcut): first, the mouse is detected to enter the video window, then move and finally exit off the video window, while the mouse doesn't move on screen
It's clearly a problem wih vlc, jvlc or java, not my prog. If you have some other solutions...

here is the whole prog
