问题


Here my issue, I have 2 Jframe, one for controlling and one for displaying things to publics. I need the display frame to be in fullscreen to avoid publics see things it doesn't need, and I need the controling frame to be usable on the other screen to control the display frame.

Here's my problem, today, I have no problem working this way in Ubuntu and a dual screen mode, but, in Windows 7 buisness 64 (don't try other version yet) The display frame actually goes fullscreen, but when i click anywhere outside the Display frame (control frame include), the display frame is automaticly minimize. I guest it's an issue with windows minimize maximize behaviour, but I really like to make it work. I know a very dirty workaround, that consists in making display frame the size of my screen and position the display frame at the good coordinate.

Here's a sample code of what I do.
To put the Displaying frame in full screen, focus the controling frame and push the key F11. or use the menu (in french)

Edit1:
I try to fullscreen both windows, but when a filechooser is called, the focus is lost because of the always on top behaviour of a fullscreen windows.

Edit 2:
I also tried to put a listener on iconified displaying jframe, but if I try to change state to NORMAL, the displaying jframe request focus, and my second frame can't be used because it lost focus

Edit 3:
If the display frame is not fullscreened, then it's not minimized when clicking on the controlling frame.


回答1:


So here my own anwser to my own problem, the workaround I finally use and I think is the only not so ugly workaround I can found is to use this code

private void jmiFullscreenActionPerformed(java.awt.event.ActionEvent evt) {                                              
     GraphicsDevice gd = this.gameFrame.getGraphicsConfiguration().getDevice();

    if (!this.gameFrame.isResizable() ) {
        //gd.setFullScreenWindow(null);
        this.gameFrame.setResizable(true);
        this.gameFrame.setPreferredSize(new Dimension(400, 300));
    } else {
        this.gameFrame.setResizable(false);
        this.gameFrame.setPreferredSize(new Dimension(gd.getDefaultConfiguration().getBounds().getSize()));
        this.gameFrame.setExtendedState(Frame.MAXIMIZED_BOTH);
    }
    refresh();
}

instead of this in my original example

private void jmiFullscreenActionPerformed(java.awt.event.ActionEvent evt) {
    GraphicsDevice gd = this.gameFrame.getGraphicsConfiguration().getDevice();

    if (gd.getFullScreenWindow() != null) {
        gd.setFullScreenWindow(null);
        this.gameFrame.setResizable(true);
        this.gameFrame.setPreferredSize(new Dimension(400, 300));
    } else {
        this.gameFrame.setResizable(false);
        this.gameFrame.setPreferredSize(new Dimension(gd.getDefaultConfiguration().getBounds().getSize()));
        this.gameFrame.enableInputMethods(false);
        gd.setFullScreenWindow(this.gameFrame);
    }
    refresh();
}

So finally I'm not using the java fullscreen function and I just use some properties of my jframe to make it look like a fullscreen frame.

Hope it help some of you !! have a nice day

this might help you

I prefer the custom way u used :) and I came up with this solution when I face the same problem but the issue is with the Java's Fullscreen API.
