TWinControl.DefaultHandler procedure
Handles all messages that the control doesn't fully handle itself.
Declaration
procedure DefaultHandler(var AMessage); overrideArguments
AMessage | The message to process. |
Description
This implementation sends the message to the widget's message handler.
Override this method to implement your own message handling. If the message Result is non-zero, the message already has been handled; otherwise, set the Result to a non-zero value (depending on the message ID) when the message has been handled.
