Thursday September 28, 2006 Centering Windows on the Screen
Here is a nifty Java trick. I wanted to center a JDialog relative to the physical screen, vs. having it appear in the upper left corner or aligned relative to another component. After a quick web search, I found the following tidbit which takes care of the issue in a single line of code (assuming you have previously created a JDialog called "dialog"):
dialog.setLocationRelativeTo(null);
Works for JFrames too, and should work for anything that with java.awt.Window as a parent, though I have only tested this with JDialog and JFrame.
