Description

Queries screen position.
FileMaker's built in functions for returning screen related information only works for the "desktop" and may include more than one screen in a Multiple monitor situation.

For version 7.1 we added support for multiple monitors for Windows.

Examples

Get the first screen's co-ordinates

MBS( "Screen.Left" ; 0 ) & "' " &
MBS( "Screen.Top" ; 0 ) & "' " &
MBS( "Screen.Width" ; 0 ) & "' " &
MBS( "Screen.Height" ; 0 )

Figure out on which screen the first window is:

Let([
    WindowCenterX = MBS( "Window.GetLeft"; 0 ) + MBS( "Window.GetWidth"; 0 );
    WindowCenterY = MBS( "Window.GetTop"; 0 ) + MBS( "Window.GetHeight"; 0 );
    $ScreenIndex = -1;

    r = While (
    [
        c = MBS( "Screen.Count" );
        i = 0
    ] ;
    i < c ;
    [
        l = MBS( "Screen.Left"; i );
        t = MBS( "Screen.Top"; i );
        w = MBS( "Screen.Width"; i );
        h = MBS( "Screen.Height"; i );
        $ScreenIndex = If(
            (l ≤ WindowCenterX) AND
            (t ≤ WindowCenterY) AND
            (WindowCenterX ≤ l + w) AND
            (WindowCenterY ≤ t + h) ; i; $ScreenIndex );
        i = i + 1 ] ; 0 )

]; $ScreenIndex)
