Actual Size of a JFrame?

[ToXSiK]

Why when I do:

gameFrame.setPreferredSize(new Dimension(800, 600));

It gives me a frame about 10 pixels less on the left and the right :/

I have done setSize method as well to no prevail.

How can I fix this so the graphics component embedded in the JFrame is actually 800 x 600

Why? Because the size includes the border area. Add a bit for the border edges. I'm not sure how to determine exactly how much. It might change based upon different "look & feels". I usually add 32 to the y-dim (JFrame vs JPanel to display on it).

Call setPreferredSize on the component embedded in the JFrame instead of the JFrame itself.

Then call JFrame.pack().

Then call JFrame.pack().

I tried that and it didn't work =/

I want it to be exact so if they game were ever to go fullscreen it wouldn't have weird offsets, and I feel like it should fit to the size I specify.  Stupid swing.

Did you set the preferred size of your embedded component, call pack on the JFrame and then do frame.setVisible(true) ? I seem to remember having some difficulty a while ago with the order of things in Swing. This is how I would do it, replacing the JPanel with whatever your embedded component is.
[CODE]
JFrame frame = new JFrame("test");
JPanel panel = new JPanel();
panel.setPrefferedSize(new Dimension(800,600));
frame.add(panel);
frame.pack();
frame.setVisible(true);
[/CODE]

How about running this code after calling setVisible(true):

1   2

Insets i = frame.getInsets(); frame.setSize(width+i.right+i.left,height+i.bottom+i.top);

Genius, thanks!  You should add me on AIM or skype, I seem to run into you a lot

Haha, glad to help

EDIT: Much cleaner code would be to set the preferredSize on the contentPane of the JFrame:

1   2   3   4   5

... frame.getContentPane().setPreferredSize(new Dimension(width,height)); frame.pack(); frame.setVisible(true); ...

Ah, "insets" -- so that is how you get the size inside the border area.
Thanks ra4king.
