The VideoLAN Forums

Hi, is it possible to have a window which contains panel, in which VLCJ plays a video, but having the window without decorations?

I tried using setUndecorated(true) on JFrame, but the video isn't rendered at all.

I tried using JWindow and still no video rendered at all.

Just a remainder: I don't want fullscreen - only decorationless window.

An undecorated, non-full-screen JFrame works just fine for me. The video plays without any problems. I use Ubuntu 11.04.

Post a single class test case of what doesn't work, and post your OS and vlc/vlcj versions.

OK, I separated enough code to make a sample, but that works

Apparently VLCJ doesn't like if the video canvas is in a panel, which is located in another panel, and that panel is located in a JFrame (so JFrame -> JPanel -> JPanel -> Canvas (VLCJ)). I tried to cut one panel, and it works (without decorations).

Edit: The bug is (surprise, surprise) in Swing. When the JFrame is decorationless, inner panel (which contains Canvas) ignores all orders to set its sizes (setSize, setMinimumSize...), when they're called from JFrame's ComponentListener's componentResized first call (e.g. when JFrame is being shown).

By ignored I mean that the same calls make impact, when JFrame has decorations... but when it doesn't the JPanel has size of [0,0].

As always, Sun shows how "great" Swing is...

Hmm... I have "decorationless" JFrame -> JPanel (content Pane) -> JPanel -> JPanel -> Canvas (vlcj). Works just fine. I wouldn't be so quick to denigrate Sun engineers or Swing.

What OS are you using? Maybe it's a platform-specific bug, if you're sure it's not your bug...

Hmm, OK, it might be Windows-specific bug, but I kind of doubt that.

I mean if I comment out line this.setUndecorated(true) in JFrame constructor, suddenly panel gets resized correctly. That sounds like a bug to me.

Well maybe you are triggering a bug. But I don't see that bug under the circumstances you describe, at least not on Linux.
