Detect mouse click anywhere on window

I've written a JWindow that acts a bit like a fancy menu in my application, popping up when a button is pressed. However, I'd like it to disappear if the user clicks anywhere in the main window. I can of course add a mouse listener to the main window, but that doesn't add it to all the components on the window itself, and looping over all the components seems like a bit of a brute force solution (and can't be guaranteed to work if the components on the window change.)

What's the best way of going about doing something like this?

Solution

  • Try to use Toolkit.getDefaultToolkit().addAWTEventListener(listener, eventMask). Find eventMask that filters only mouse clicks. This AWT listener is global for whole application, so you can see all events that happen.
