This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
We have a swing application, where component sizes are set relative to screen size (this is a *strict* requirement from the customer). Example: some frame should occupy exactly 1/2 the screen width & height. So (eliminating insets for simplicity):
The problem is, it doesn't work when user changes screen resolution at runtime. For instance: 1. Invoke the program with a 800x600 resolution: frame will pop up with 400x300 size 2. While frame is showing, change screen resolution (through the operating system) to 1280x960 3. Now, of course, frame is still 400x300 , which is no longer half the screen. Customer would like to to be fixed (1280/2 , 960/2).
Could anyone offer a solution to this ? In particular, is there any sort of event we can catch to be notified of screen resolution changes ? (I have considered overriding the frame's paint(Graphics) method, because I've noticed that, at least on winXP, frames are minimized & then maximized when resolution changes; which triggers a call to paint(). So one could override paint() so that it re-checks frame size... but this does not seem very elegant ).
