Hi,

I have a JFrame with a menu bar and inside the the frame a canvas. When I
click on a menu item
the menu is always (partly) drawn behind the canvas. How do you set the
options that will draw the menu(bar) to be visible ?

thanks

Johan

AWT

Swing and the AWT do not play
together, use one or the other.

JPopupMenu.setDefaultLightweightPopupEnabled(false);

But otherwise, do as the others have suggested and don't mix Swing and
heavyweight AWT components.
