A SftMask object.

KeyCode

Describes the virtual key pressed. See your development environment documentation for available key code constants.

Shift

Describes the state of the SHIFT, CONTROL and ALT keys. A bit is set if the key is down. The Shift argument is a bit field with bits corresponding to the SHIFT, CONTROL and ALT keys. It indicates the state of these keys. Some, all, or none of the bits can be set, indicating which of the keys are pressed.

ShiftValueDescription
constSftMaskShiftMask1The SHIFT key is down.
constSftMaskCtrlMask2The CONTROL key is down.
constSftMaskAltMask4The ALT key is down.

Comments

The KeyDown event occurs when a key is pressed.

If the control is part of a parent window (form, dialog, etc.) which has a default button (OK, Cancel) and the user presses the ENTER or ESCAPE keys, this event is not generated.

The KeyDown event is never generated for the TAB key.

To interpret keyboard characters (ANSI characters) use the KeyPress event.

The key typed by the user can be suppressed by setting KeyCode to 0.
