Hi guys!
I'm working on this project that will be a Java Applet, using Swing, but I guess you can awnser me in the normal windows way of doing this :)
The idea is basically to have a single 'frame' (window..), but the entire content would change upon some action - exactly like the next dialogs! It would start off as two labels and textboxes asking for username and password + login button... Then depending on correctness of login, the contents would change to be, eg the main menu... Upon choosing some option, the contents would change to be blah... But I really have no idea how to create such a thing! I can easily acomplish it in multiple windows, but I want to keep the seamless transition going, like the installation dialogs with the next, next, next... Any help?

You will have to use different layout managers.
But your frame will probably need to use the CardLayout Manager. I did something similar to this about a year ago.

I was thinking of a borderLayout for the main frame... Also, how do I add blank spaces in a BorderLayout? As in I want a blank on all borders and content only in the center? The basic template for all "pages" is
The applet will be alot larger in size though...
One thing is, I would like some of the frames destroyed when the page changes... or it's contents diminished, as the project will incorporate a miniature message board and polls... So it's not wise to keep the polls always loaded as well as the messages...

sample only... pic at the bottom
you can also try multiple panels/frames/windows whatever... hiding... showing... resizing... relocating... adding pictures...
a similar idea would be like property pages(frames/panels/??) in win32.
my java is kinda rusty so the code above may not be the best solution. And I may be talking rubbish to you. :grin:

That's pretty close to what I originally thought... But I had envisioned that I switch the middle pane to the apropriate one, depending on the one the user should see at that moment. The content can dramatically change from a set of buttons to option boxes to text areas... I'll read up on the card layout :)
