SCREEN COORDINATES


SCREEN COORDINATES ( left ; top ; right ; bottom {; screenID {; screenArea}} )

Parameter	Type	Description
left	Longint	Global left coordinate of screen area
top	Longint	Global top coordinate of screen area
right	Longint	Global right coordinate of screen area
bottom	Longint	Global bottom coordinate of screen area
screenID	Longint	Screen number, or main screen if omitted
screenArea	Longint	Entire screen (default) or working area

Description

The SCREEN COORDINATES command returns in left, top, right, and bottom the global coordinates of the screen specified by screenID.

If you omit the screenID parameter, the command returns the coordinates of the main screen.

The optional screenArea parameter lets you specify if you want the coordinates for the entire screen area (default) or only for the available usable area. Two selectors are available:

Constant	Value	Comment
Screen size	0	The coordinates of the entire screen. (default value)
Screen work area	1	The coordinates of the available screen area that can be used (i.e., they are not occupied by Windows taskbar or macOS menu bar and Dock).

The following images demonstrate the differences between the screen size and the work area:

Notes:

If the taskbar or dock is automatically hidden, SCREEN COORDINATES always returns the entire screen size.
If an invalid value is given in screenID or screenArea, a zero is returned for all of the coordinates.
