Description
The OnMouseMove event is triggered continually as the mouse moves over the MapControl.
button specifies which mouse button was pressed. 1 for the left mouse button, 2 for the right mouse button, and 4 for the middle mouse button.
shift specifies an integer corresponding to the state of the SHIFT (bit 0), CTRL (bit 1) and ALT (bit 2) keys. When none, some or all of these keys are pressed none, some or all the bits get set. These bits correspond to the values 1, 2, and 4, respectively. For example, if both SHIFT and ALT were pressed, ShiftState would return 5.
x is the X coordinate, in device units, where the mouse button was pressed referenced against the origin (0, 0) of the MapControl (the top left hand corner).
y is the Y coordinate, in device units, where the mouse button was pressed referenced against the origin (0, 0) of the MapControl (the top left hand corner).
mapX is the X coordinate, in map units, where the mouse button was pressed referenced against the origin (bottom left hand corner) of the IMapControl2::Map. The values returned are in IMapControl2::MapUnits.
mapY is the Y coordinate, in map units, where the mouse button was pressed referenced against the origin (bottom left hand corner) of the IMapControl2::Map. The values returned are in IMapControl2::MapUnits
