[Qt4-preview-feedback] Qt-4.5 RC1: Calling QWidget::activateWidget has opposite effect

[Thomas Sondergaard]

With CentOS 5.2 gnome/metacity and Qt-4.5-RC1 the label in the following 
program will lose focus, rather than gain focus by calling 
QWidget::activateWidget. If the app.processEvents() invocation is 
uncommented it works. This is a regression from 4.4.3.

I understand that calling QWidget::activateWindow is typically not 
necessary or desirable in this situation. I just stumbled over this and 
thought I'd report it.

#include <QApplication>
#include <QLabel>

int main(int argc, char *argv[]) {
   QApplication app(argc, argv);

   QLabel w("Hello World");
   w.resize(1000, 1000);

   w.show();
//   app.processEvents();
   w.activateWindow();

   return app.exec();
}
