Show images on the screen without using JFrame

[Devasia Manuel]

I am dying to know how you can show images and swing components on the screen without putting in all in a Jframe first. I know there is a way of doing it, I just dont know how.

Thanks

I believe that you have to use some root container but that it doesn't have to be a JFrame. You could use a JDialog, a JOptionPane, or a JWindow. You could set your app to have no "decorations", no titlebar, or resize/exit buttons if desired. I suggest that you study the Sun Swing tutorials for more detail. Good luck.

Pete Stein is correct, but the actual list of top-level containers is (I think) Window Frame Applet and Dialog. Frame includes JFrame (as a subclass) (etc), and what you get from JOptionPane is actually a Dialog.

[Rob Spoor]

Technically there is only one top-level container class: Window. Frame, Dialog and JWindow are subclasses of Window.

[Campbell Ritchie]

Yes, you're right, Rob. But what about Applets? Don't they count as top-level too?

[Rob Spoor]

No, they are still in a Frame. I've retrieved it for showing modal dialogs.

Of course you should treat Applets as top-level as far as creating components goes (i.e. you don't add it to anything yourself), but it certainly is not a top-level component in the same way as Frame or Dialog are.

Thank you.

[Devasia Manuel]

Well then in that case, how do I take off the tilte bar and the border?

[Campbell Ritchie]

Either use a JWindow or find the thread from the end of March last year about how to take buttons off a JFrame.

[Rob Spoor]

setUndecorated(true) is the other way to do it.

[Campbell Ritchie]

I think that post did mention setUndecorated, but I could remember when it was posted, better than I could remember setUndecorated.
