restrictions on resizing JFrame

[Jhedzkie Skies]

hi there.

i just want to ask,

well, i have here a JFrame size set as 1024 x 768.
it is resizable.

what i want to know is, how can i restrict the frame from resizing when it reaches 800 x 600?

i mean, when resized, the smallest possible size of the frame must be 800 x 600 and will not go smaller than that.

any suggestions are very much appreciated. thank you.

Try out setPreferredSize()

presume you mean resize smaller

the only way I've seen possible do do what you want is to add this line
(prior to creating the frame)
JFrame.setDefaultLookAndFeelDecorated(true);
then
frame.setMinimumSize(new Dimension(800,600));

problem is java's default L&F is not the best looking.

a hack is to add a windowListener which snaps it back to 800,600 if smaller,
then, when snapped-back, you could add code to make it not resizable

Actually, since Java 5.0 the call to JFrame.setDefaultLookAndFeelDecorated(true); is no longer needed. The minimum size is now adhered to with at least the default look&feel (Metal), the Motif look and feel and the Windows look and feel.
