Stored procedures
Used in an linked event with the mouse or the stylus (click code, hover code, left or right button pressed code, ...) returns the horizontal (X) position of the mouse cursor in relation to the control or the window considered.
You can find out:
  • the position of the mouse (or stylus) when left-clicking in an Image control (function used in the "Click" event of the Image control).
  • the position of the mouse (or stylus) when hovering over a window (function used in the optional "Mouse hover" event of a window).
Remarks:
  • Java It is advisable to use this function only in events in fields hovered with the mouse.
Example
Reports and QueriesJavaUser code (UMC)
// "WIN_Drawing" window hovered by the mouse
// Optional code of the window
Message("Position of the mouse: X: " + MouseXPos() + "Y: " + MouseYPos())
Reports and QueriesJavaUser code (UMC)
// Displays a different message according to the location clicked
IF MouseXPos() > 25 THEN
Info("To the right")
ELSE
Info("To the left")

Retrieving the mouse position in a window Hide the details

<Result> = MouseXPos([<Marker>])
<Result>: Integer
  • Horizontal position (or X coordinate) of the mouse (or stylus) in pixels. By default, this position is given in relation to the top left corner of control on which the left mouse button was pressed.
  • -1 if an error occurred.
<Marker>: Optional Integer constant
Versions 17 and later
Marker used to calculate the position:
mpControl
(Default value)
Mouse position relative to the top left point of the hovered control (or of the window if the event is on the window).
mpScreenMouse position in the screen (in relation to the top left corner of screen).
mpWindowMouse position in relation to the top left corner of window.
mpImageMouse position in the Image control (relative to the top left corner of the Image control).

This constant should only be used when the function MouseXPos is called in an event associated with an Image control. Otherwise, MouseXPos will return -1.
