TWinControl.ControlKeyDown procedure

Declaration

procedure ControlKeyDown(var Key: Word; Shift: TShiftState); virtual

Description

ControlKeyDown is a method used to detect and handle key down events for navigation keys used in the control. ControlKeyDown calls the corresponding method in TApplication to determine the actions needed for the key and modifier. The application handles Tab and cursor keys which may affect control or form focus.

ControlKeyDown is called from the DoRemainingKeyDown method to handle keys not otherwise handled by a control or its parent forms.
