Java Swing; How do I make it so the program starts on the right most hand of the screen?

Question

By default, my Swing program starts at the top left hand side of the monitor. Is there a way to make it so it pops up at the right hand side?

What about dual monitors? Can I get it to pop on the right monitor?

Thanks.

Answer 1

Assuming you don't want to cover up the taskbar, you should use getMaximumWindowBounds.

Centering JFrame’s

By default, a Jframe is displayed in the upper-left corner of the screen. To display a frame at a specified location, you can use the setLocation(x, y) method in the JFrame class. This method places the upper-left corner of a frame at location (x, y).

Your pseudo code for the top right corner looks something like this:

yourJFrame.setLocation(
  GraphicsEnvironment.getMaximumWindowBounds().getWidth() - 
  yourJFrame.getWidth(), 0);

Answer 2

For displaying at another initial location, take a look at JFrame.setLocation()

For displaying on another screen, take a look at avaible infos from GraphicsEnvironment.getScreenDevices().

Answer 3

There are many questions/answers about using GraphicsEnvironment to do similar things.

You can use GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices() to get all the monitors, then call GraphicsDevice#getConfigurations and then GraphicsConfiguration#getBounds to get the size and location of each monitor, then use your high-school geometry to find the "right" monitor. (Note that a true multi-monitor setup can put them in arbitrary location.)
