I've noticed that there isn't a thread on swing so i'll post this here.

Plain and simple. I'm building a 2D map editor program using swing which loads a tile set. I'm using a JPanel which controls the map editor. It's set up in a grid reference (rows/cols determined by the user) and wherever the user clicks in the grid, the selected image, gets placed in that position. Once done, it saves the 2D array into a text file. Which is the map file used for my game programs.

My question is, why is it that my JPanel overlaps the JMenuBar whenever I select a menu? I'm going to assume it's because my JPanel uses double buffering in a thread which causes the overlapping. Or that JMenuBar is heavyweight, although i thought that all swing components are lightweight apart from japplet/jframe. I'm avoiding this problem atm by readjusting the JPanels position away from the Menus. But i'm curious to know what's going on.

Yep, it was the double buffering for the JPanel, however for a canvas with no double buffering, the same thing happens. Now how do i fix this? haha

Well now, this post is pointless. I found a fix to both the Canvas and JPanel problem. Good old heavyweight components Smiley

JPopupMenu.setDefaultLightWeightPopupEnabled(false);
