+    \class QxtApplication QxtApplication
+    \ingroup QxtGui
+    \brief An extended QApplication with support for hotkeys aka "global shortcuts".
+
+    QxtApplication introduces hotkeys which trigger even if the application is not
+    active. This makes it easy to implement applications that react to certain
+    shortcuts still if some other application is active or if the application is
+    for example minimized to the system tray.
+
+    QxtApplication also lets you install native event filters. This makes it
+    possible to access platform specific native events without subclassing
+    QApplication.

+
+    A native event filter is an object that receives all native events before they reach

+    the application object. The filter receives native events via its platform specific
+    native event filter function. The native event filter function must return \b true
+    if the event should be filtered, (i.e. stopped); otherwise it must return \b false.
