The event handler that is called before the event dispatcher of the control class.
<oBrowser>:EventHandler(<oEvent>) Æ uResult
|<oEvent>||The event that is to be processed.|
|uResult||The result of the event processing.|
The event dispatcher of the control class has the unpleasant peculiarity that not all events necessarily get sent there by Microsoft Windows. Some events are intercepted and processed and are not passed on. For this reason the class bBrowser possesses its own event handler that is called before the event dispatcher of the control class and so gets all events from Microsoft Windows.
By returning a value other than NIL, the event is NOT passed on to the control dispatcher. In this case the method must process the event.
