    Retrieving the mouse position in a window Hide the details

    <Result> = MouseXPos([<Marker>])
    <Result>: Integer
    • Horizontal position (X-coordinate) of the mouse or stylus, in pixels. By default, this position is relative to the upper-left corner of the control on which the left mouse button was pressed.
    • -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 hovered control or window, depending on where the event occurs.
    mpImageMouse position in the Image control (relative to the upper-left corner).

    This constant should only be used when MouseXPos is called in an event associated with an Image control. Otherwise, MouseXPos 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.
