WINDOW LIST


WINDOW LIST ( windows {; *} )

Parameter	Type	Description
windows	Array	Array of window reference numbers
*	Operator	If specified, take floating windows into account If omitted, ignore floating windows

Description

The WINDOW LIST command populates the array windows with the window reference numbers of the windows currently open in all running processes (kernel or user processes).

If you do not pass the optional * parameter, floating windows are ignored.

Example

The following project method tiles all the current open window, except floating windows and dialog boxes:

  ` TILE WINDOWS project method

 

 WINDOW LIST($alWnd)

 $vlLeft:=10

 $vlTop:=80 ` Leave enough room for the Tool bar

 For($vlWnd;1;Size of array($alWnd))

    If(Window kind($alWnd{$vlWnd})#Modal dialog)

       GET WINDOW RECT($vlWL;$vlWT;$vlWR;$vlWB;$alWnd{$vlWnd})

       $vlWR:=$vlLeft+($vlWR-$vlWL)

       $vlWB:=$vlTop+($vlWB-$vlWT)

       $vlWL:=$vlLeft

       $vlWT:=$vlTop

       SET WINDOW RECT($vlWL;$vlWT;$vlWR;$vlWB;$alWnd{$vlWnd})

       $vlLeft:=$vlLeft+10

       $vlTop:=$vlTop+25

    End if

 End for

Note: This method could be improved by adding tests on the size of the main window (on Windows) or the size and location of the screens (on Macintosh).
