Package

capi

screen-monitor-geometries screen => monitor-geometries

Arguments

screen

A CAPI screen.

Values

monitor-geometries

A list of screen rectangles.

Description

The function screen-monitor-geometries returns the geometries of all the monitors of screen. A monitor corresponds to an entity that the host machine regards as a physical monitor. screen-monitor-geometries ignores software manipulations like the desktop on GTK+.

The monitor geometry is a rectangle which includes all of its display area, including "system areas" like menubar and taskbar and so on. Examples of these include the Windows taskbar, the Mac OS X menu bar and the Mac OS X Dock.

Each monitor geometry screen rectangle is represented by a list of four numbers: the x and y coordinates as offsets from the top-left of the primary monitor, and the width and height .

The first screen rectangle in the monitor-geometries list corresponds to the primary monitor.

Notes
  1. screen-monitor-geometries differs from screen-internal-geometries by returning screen rectangles which include all the monitor areas, and also by ignoring desktop manipulations.
  2. You cannot display a CAPI window on the Mac OS X menu bar. You can display a CAPI window in the area occupied by the Mac OS X Dock or the Windows task bar, but the window will be obscured.
