How to adjust an application (JFrame) with every kind of screens?

问题

i have been working on a Swing application that has a JFrame as principal Frame and it contains a lot of JInternalFrames inside of it , and when i installed it in every computer in the company, it seems that some computers screen size is lower and more tight then the screen in wish i had developed my application, and that is not useful, so i am asking if i can adjust my application (Frames) to every kind of screen size, i am using Swing API.

Thank you.

You can check the size of the screen like this:

 Dimension screen = Toolkit.getDefaultToolkit().getScreenSize();

Then you can decide how much of the screen you want to cover. Say half the size of the screen.

 int h = screen.height / 2;
 int w = screen.width / 2;

Then set your JFrame to this new height and width.

myFrame.setSize(new Dimension(w, h));

Of course you will have to experiment a bit to see what size works for all your screen sizes. Alternatively you can simply maximise the Frame on start up.

you can get the local maximum resolution with

GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();
            Rectangle desktopBounds = env.getMaximumWindowBounds();

then you can adjust your application accordingly note that this is in AWT but for me it still got the right result
