Archived:Qt Key Event test example

Comments

Is this application really "maemo" specific as tagged, or is it just that its only been tested on Maemo? If its generic code, please remove the maemo category.

This code example demonstrates how to control key events from a Qt application on Maemo.

When a widget has the keyboard input focus, key events are sent to it when keys are pressed or released. Sometimes the developer wants to use events from keyboard to perform custom action, such as control in games. It can be done by reimplementing the virtual protected method QWidget::keyPressEvent in a class which inherits from QWidget.
