JPanel question.

[santa]

I decided to work with JPanels in staid of JInternalFrame. The JPanel will be displayed inside another JPanel (MainPanel) at the mouse pointer and will contain information about the object that was clicked on by the mouse.
So my question is; Is it better to create a new panel every time the panel is to be displayed or "show and hide" the panel with new data in staid?
Also will it work if i just add the new panel to the "MainPanel" and then use the setlocation(x,y); to position it by the mouse?

Thanks...

That depends on what your definition of "better" is as well as the specifics of your requirements (where your data is coming from, what's being displayed, what changes, etc) . I'd recommend you do a test of each and decide for yourself.

As for adding the new panel, you might want to make sure you remove old panels, and you have to keep in mind things like overlapping components, revalidating, etc. You might want to look into adding it to a GlassPane instead.

Sounds like its better to use the glassPane ... If i want to add a JPanel on the glasspane should I use the default glassPane? I have no experience with the glasspane. Thanks

Yeah ... I didn't try yet :P still reading about it in How to Use Root Panes (The Java™ Tutorials > Creating a GUI With JFC/Swing > Using Swing Components). Im still amazed by that my java book has zero on the glassPane ..
