Example

Executing the example requires a form. Several components that can receive focus are placed on the form. The following procedure is used as a handler of the OnKeyDown event for all components:

Sub ProcedureOnKeyDown(Sender: Object; Args: IKeyEventArgs);

Begin

If (Args.ShiftState = ShiftState.Ctrl) And (Args.Key = Keys.B) Then

Text := (Sender As IControl).Name;

End If;

End Sub ProcedureOnKeyDown;

After executing the example, if CTRL+B was pressed in the area of any component, the name of this component is displayed in the form name.
