Disable repositioning of JFrame

[divs1210]

Hey! I am developing an application that i don't want the user to be able to drag across the screen.

any possible way i could do that?

[divs1210]

also, how can i change the color of the frame?

setBackground(Color.WHITE); seems to have no effect.

im sorry if this has already been asked. just give me a link to that page.

try this...

FrameName.setResizable(false);

I'm not sure how to disable dragging of the JFrame, but to set the background to white, you'll need to get the JFrame's contentPane (via getContentPane()) and set its background via setBackground().

@ujjal ive already set resizing to false.
@Fubarable oh, yes. what was i thinking? thanks!

i don't want the user to be able to drag across the screen.

I have to ask, why? If I found this behavior in any application, I would immediately uninstall it.

Anyhow. One way is to use a JWindow instead of a JFrame, as it doesn't have a title bar and so can't be dragged. Another way is to setUndcorated(true) on a JFrame, which removes its title bar.

In either case, you'll need to provide a means for the user to close the application. Or do you want to prevent that too?

You can't 'forbid' a JFrame from being moved, it's part of the system GUI; the best you can do is add a ComponentListener to the JFrame and put it back at its original place when it's being moved. I think the visual effects are quite funny.

Oh Sorry,
I thought that you wanna disable sizing.You wanna make stable your window? That's not done.I dont know how to do this,just you can't prevent an user to do this.

Night here, now (evening when you posted that).

India just won, crackers being set off all around so my dog has squeezed between my feet and the computer table.

I still feel you ought to rethink the requirement. It's abnormal.

Seconded. Perhaps you have a good reason for wanting to do this, but you may wish to justify this reason with us.

well, i'll tell u my idea in brief:


i actually wanted a window with a transparent frame. I thought ill do that the way picassa does it, u know, when it's in full-screen mode, it just captures a pic of the desktop, and pastes it as a background.

but when u minimise it, it just shows a grey background, because if u move the window, the background should change.

my application runs ONLY in windowed mode, so the above problem is a serious one. i read somewhere that the best option to tackle this would be to capture a new picture everytime the window is moved. but i felt too lazy, and though there *might* be a way to stop repositioning it, killing the need for everything else in the first place.

....but i get u. its NOT a good idea. so i'll not do it.
