Hi,
i need to develop a gui which will load several "windows" depending on what the users selects in the menu and i thought i could accomplish this with panels.
What i'm trying to do to test this is load an initial panel and then when the user hits a button load a second panel. This doesn't seem to work.
1. what's the appropriate way of switching panels? 2. the loadNewPanel function seem wrong. I always get loading panel two".
Thanks, Benedict
