Retrieving the mouse position in a window Hide the details

<Result> = MouseYPos([<Marker>])
<Result>: Integer

  • -1 if an error occurred.
<Marker>: Optional Integer constant
Marker used to calculate the position:
mpControl
(Default value)
Mouse position relative to the upper-left corner of the control or window, depending on where the event occurs.
mpImageMouse position in the image (relative to the upper-left corner of the image).

This constant should only be used when MouseYPos is called in an event associated with an Image control. Otherwise, MouseYPos will return -1.
mpScreenMouse position in the screen (relative to the upper-left corner).
mpWindowMouse position relative to the upper-left corner of the window.
