The state of the SHIFT, CONTROL and ALT keys during the event (see SftTreeKeyConstants). 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. The Shift variable indicates the state of these keys. Some, all, or none of the bits can be set, indicating which of the keys are pressed.

constSftTreeShiftMask1The SHIFT key was pressed.
constSftTreeCtrlMask2The CONTROL key was pressed.
constSftTreeAltMask4The ALT key was pressed.


The KeyUp event occurs when a key is released.

The KeyUp event is generated when the user releases a key while the tree control has the input focus. The KeyUp event is not generated during cell editing.

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

The KeyUp 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. It can be modified by assigning a new value to the variable.
