Place a JButton over the visualcomponent

Question

Hi to all.
I'm a newbie to JMF.
What I'm trying to do with no success is to add a permanent feature lets say a button on top
of the visualComponent given from the player.
It is impossible for the moment.
I'm really desperate beacause I can't find a way out.
For whom has already worked with JMF it sould be easy but not for my.
Any hint or help Would be really wonderful
Thanks to all in advance
Mandy

Yes. Make sure that you move it behide the control. To do so click on just
the label then go to the reorder control on the toolbar and select move it
backward or move it to back.
