Button

The button that is pressed during the event (see SftTreeButtonConstants). The button argument is a bit field with bits corresponding to the left button, right button and middle button.

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.

Comments

The MouseUp event occurs when a mouse button is released.

1) Depending on the settings of the LeftButtonOnly or LeftItemClickOnly properties, this event may not be generated for the middle and right mouse buttons.

The MouseUp event can be used by an application to handle mouse button clicks in combination with keyboard modifiers such as the SHIFT, CONTROL and ALT keys.

The ItemClick event should be used if specific information about the logical position of the mouse cursor is needed.

If the MouseUp event is used to display a context sensitive menu (popup menu), the CancelMode method must be used before displaying the context menu.
