MouseMove Event

 

MouseMove Event

The MouseMove event is generated continually as the mouse pointer moves across the grid.

Syntax

object_MouseMove (Button As Integer, Shift As Integer, X As Single, Y As Single)

Arguments

Button is an integer that corresponds to the state of the mouse buttons in which a bit is set if the button is down. 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. The Button argument indicates the complete state of the mouse buttons; some, all, or none of these three bits can be set, indicating that some, all, or none of the buttons are pressed.

Shift is an integer that corresponds to the state of the Shift, Ctrl, and Alt keys. A bit is set if the key is down. 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.

X and Y are single-precision numbers that specify the current location of the mouse pointer. They are always expressed in terms of the coordinate system of the grid's container.

Remarks

This event is primarily useful for implementing drag-and-drop behavior on a per-column basis.
