#GUI.ShowWindow

##Syntax GUI.ShowWindow (window : int)

##Description Hides a window with widgets in it. This procedure makes certain that the GUI Library recognizes that the window no longer visible. This procedure will call Window.Hide, so there is no need for the user to do so.

##Example The program opens up a window with two buttons. If the button labelled "Close and Open" is pressed, the window is closed and a new window with two buttons is opened in a random location on the screen.

    import GUI

    var windowA, windowB : int
    var buttonA, buttonB, buttonQuit : int
var backToMainA, backToMainB : int

    procedure ShowWindowA
        GUI.HideWindow (defWinID)
        GUI.ShowWindow (windowA)
    end ShowWindowA

    procedure ShowWindowB
        GUI.HideWindow (defWinID)
        GUI.ShowWindow (windowB)
    end ShowWindowB

    procedure ShowMain
        GUI.HideWindow (Window.GetActive)
        GUI.ShowWindow (defWinID)
    end ShowMain

    View.Set ("graphics:280;100,nobuttonbar")
    % Place the buttons in the main window
    buttonA := GUI.CreateButton (10, 10, 0, "Show Window A", ShowWindowA)
    buttonB := GUI.CreateButton (150, 10, 0, "Show Window B", ShowWindowB)
    buttonQuit := GUI.CreateButton (100, 60, 0, "Quit", GUI.Quit)

    windowA := Window.Open  ("title:Window A,graphics:150;100,position:bottom;left")
    backToMainA := GUI.CreateButton (20, 20, 0, "Back to Main", ShowMain)
    Window.Hide (windowA)
    windowB := Window.Open  ("title:Window B,graphics:150;100,position:bottom;right")
    backToMainB := GUI.CreateButton (20, 20, 0, "Back to Main", ShowMain)
    Window.Hide (windowB)

    loop
        exit when GUI.ProcessEvent
    end loop
