Change Display Used for Eclipse Launches

I'm developing开发者_Go百科 a Swing-based Java application in Eclipse on Windows XP. I have a dual monitor setup.

I want to have the program launch on a different monitor than the one I'm running Eclipse in. How can I set up my Debug Configuration to make this happen?

When a new frame is opened, it defaults to coordinates 0,0. Exactly where this is depends on your operating system's monitor layout. Typically, 0,0 will be the upper-left corner of the primary monitor.

The solution to your problem is to run Eclipse on your secondary monitor, so that the applications will open on the other (primary) monitor. You don't actually have to move Eclipse to do this. Go into your operating system's monitor settings and switch the primary monitor to the monitor you wish to start the application on. Eclipse will now be running on the secondary monitor.

Your new frame will now be opened on the other monitor, and you have changed no code in the process, just your operating system's configuration settings.

It depends a bit how you did set up your second monitor. For my answer, I'm assuming that you added it as an "extension" to your desktop (so you can move windows between them by dragging with the mouse).

In this mode, your desktop becomes bigger. To see that, call GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds.

The width should be the sum of the widths of your two monitors and the height should be the larger of the two heights.

Note that the x coordinate can be < 0 (this happens if your make the right monitor the default one).

To move your window to the other monitor, simply use a position (setPosition()) with an appropriate value and pass that position as an option to the program. Or save the current position as a preferences node and open the window again in the same place when the app is run again.

If your monitors are configured independently, you should look into the GraphicsEnvironment.getScreenDevices() API.

I think you can't do that. The only solution I found is to move the program from the first display to the second one manually and then close it in this position (with the close button and not the Console terminate red button that stop brutally the VM without saving anything). Then on the next restart, your program launch should appear on the second display. In order to have this solution working, your launch configuration should not clear the workspace and the config at each launch in order to keep the programm screen location.

See RCP opening monitor for related stuff on RCP app.

You can probably achieve that behavior programmatically. I'm sure you can Google and find examples of how to open your window on the second monitor. If it is something you want only at debug-time, add a switch in your launch configuration (more specifically, a JVM runtime argument) and check for the switch (System.getProperty) when your program starts.
