Hello to all,

I have created an application containing a JTree and a Text Area. I have included popup menu in JTree i.e. by right clicking on any leaf of JTree a popup menu appears having two options
1) Start Display
2) Stop Display
But the problem is that, popup menu is only displayed when TextArea is not visible in frame and as soon as i expand or maximize the frame the right click stop responding, or in other words popup menu does not works.
Can any body tell me whats the problem ???

Which component have you added the mouse listener to that pops up your menu?  Sounds like when you expand your window the mouse is no longer over your (mouse listener) component.

>  when TextArea is not visible in frame

use JTextArea instead of TextArea. TextArea is heavyweight component and will 'hide' all the Swing components.

What does it mean to be "Always On"?

I reckon it's a layout issue, and when you resize your mouse listener is not growing with your frame.
