TCustomCheckCombo.KeyDown procedure
Handles key down events for the control.
Declaration
procedure KeyDown(var Key: Word; Shift: TShiftState); overrideArguments
Key | Key examined in the method. |
Shift | Keystroke modifier examined in the method. |
Description
KeyDown is the overridden method used to handle key down events
for the control. KeyDown ensures that Return (
VK_RETURN) and Space
(
VK_SPACE) are applied to the control. Return causes the value for
an enabled item to be toggled when highlighted. Space also toggles the value
in an enabled check box, and makes the item selected before hiding the drop
down for the combo-box.
KeyDown calls the inherited method.
