[Xnee-devel] Switching screen resolution moves my program window and xne

From: Veijo Ryhänen
Subject: [Xnee-devel] Switching screen resolution moves my program window and xnee cannot follow it.
Date: Wed, 11 Jan 2006 13:36:11 +0200


I have recorder several xnee -tests in 1024x768 screen resolution, but
I cannot play back them in 1280x1024 -resolution, because
my program window position in screen is changed every time
when screen resolution is changed and there is no --offset x,y
-switch available in cnee.

Should I throw away my old xnee -tests and start to record new
tests with 1280x1024 resolution ? Other developers seems to prefer
1280x1024 resolution and it is not good if they have to change
their screen resolution if they would like to run tests which I have
As a matter of fact, every programs we have write in java use
this same window screen position technology as showed in
this sample code attachment.

To compile sample code:
javac CenteredWindow.java

To run sample code:
java CenteredWindow

 * Title:       CenteredWindow
 * Description: Opens fixed-size window which is allways centered on the screen -> Upper left corner
 * position moves (=offset) when screen resolution is changed -> xnee replay does not work
 * after screen resolution change, because window location is changed too and there is
 * no "--offset x,y" -switch currently available in xnee or cnee.
 *"--recorded-resolution 1024x768 --replay-resolution 1280x1024" -switches does not help in this case.
 * Sample outputs to console when running in two different screen resolutions:
 * Upper left corner inserted to: 12,34  ScreenSize:1024.0,768.0  WindowSize:1000.0,700.0
 * Upper left corner inserted to: 140,162  ScreenSize:1280.0,1024.0  WindowSize:1000.0,700.0
