object
A SftButton object.
Button
Describes the button(s) that are pressed. The Button argument is a bit field with bits corresponding to the left button, right button and middle button. These bits correspond to the values shown below. The bits set indicate the button that caused the event.

| constSftButtonLeftButton | 1 | Left button |
| constSftButtonRightButton | 2 | Right button |
| constSftButtonMiddleButton | 4 | Middle button |
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.
| Name | Value | Description |
|---|
| constSftButtonShiftMask | 1 | Shift |
| constSftButtonCtrlMask | 2 | Control |
| constSftButtonAltMask | 4 | Alt |
xPos
The x-coordinate of the mouse cursor. The units used depend on the container (Visual Basic uses TWIPS, Visual C++ uses pixels, etc.) and the coordinate system used.
yPos
The y-coordinate of the mouse cursor. The units used depend on the container (Visual Basic uses TWIPS, Visual C++ uses pixels, etc.) and the coordinate system used.
Comments
The MouseDown event occurs when a mouse button is pressed.
The Click and DropDownClick events should be used to determine whether the control has been clicked.
The MouseDown 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 HitTest method can be used to determine what area of the control is at a specific location.
