[Qt-interest] QMainWindow size...

[David Boosalis]

mainWindow->setFixedSize(SCREEN_WIDTH, SCREEN_HEIGHT);
mainWIndow->show();


Incidently  if your sizes are done with defines like:
#define SCREEN_WIDTH 640
#define SCREEN_HEIGHT 480

a more robust way is to you use QDesktopWidget:

QDesktopWidget *desktop = qapp->desktop();
QRect r = desktop->screenGeometry;
mainWindow->setFixedSize(r.width(),r.height());

Hope this helps
