public procedure TWinControl.BroadCast( |
var ToAllMessage |

ToAllMessage |
|
The message sent in the method. |
Allows the specified method to be handled by one of the child Controls. The ToAllMessage argument is untyped; any TLMessage descendant can be passed as the value for the argument.
The method name is a misnomer. Broadcast implies delivery of the message simultaneously to all of the recipients. Actually, it is more like a telegraph. The message is posted sequentially to child controls until one of them handles the message using its WindowProc method.
Use NotifyControls to post a message with a specific message identifier constant to child Controls in the class instance.
