Public Event MouseWheel( _ ByVal Button As Integer, _ ByVal Shift As Integer, _ ByVal Delta As Integer, _ ByVal X As Integer, _ ByVal Y As Integer _ )
- Returns an integer that identifies the button that was pressed to cause the event. The Button argument is a bit field with bits corresponding to the left button (bit 0), right button (bit 1), and middle button (bit 2). These bits correspond to the values 1, 2, and 4, respectively. Only one of the bits is set, indicating the button that caused the event.
- An integer that corresponds to the state of the SHIFT, CTRL, and ALT keys at the time of the event. The Shift argument is a bit field with the least-significant bits corresponding to the SHIFT key (bit 0), the CTRL key (bit 1), and the ALT key (bit 2). These bits correspond to the values 1, 2, and 4, respectively. Some, all, or none of the bits can be set, indicating that some, all, or none of the keys are pressed. For example, if both CTRL and ALT are pressed, the value of Shift is 6.
- Gets a value that indicates the amount that the mouse wheel has changed.
- Returns a number that specifies the x-position of the current location of the mouse pointer. The x and y values are always expressed in terms of the control window coordinate system.
- Returns a number that specifies the y-position of the current location of the mouse pointer. The x and y values are always expressed in terms of the control window coordinate system.
Occurs when the mouse wheel moves while the control has focus.
The MouseMove event is generated continually as the mouse pointer moves across the control.
These constants act as bit masks you can use to test for any combination of buttons without having to figure out the unique bit field value for each combination.
In VB.NET the MouseWheel event is shown as "xxxxxxxx_MouseWheelEvent" in the IDE.
