#GUI.SetPositionAndSize

##Syntax GUI.SetPositionAndSize (widgetID, x, y : int, width, height : int)

##Description Changes the position and size of the widget specified by widgetID simultaneously. The x, y, width and height parameters have the same meaning as in the GUI.Create function for that widget. Any widget except a menu or a menu item can be resized, although for some widgets, the width or height parameter may be ignored.

GUI.SetPositionAndSize works the same way as the GUI.SetPosition and GUI.SetSize procedures.

##Example The following program moves and resizes the button every time the button is pressed.

    import GUI in "%oot/lib/GUI"
    
    var button, minWidth, minHeight  : int
    
    procedure MoveButton
        var newX, newY, newWidth, newHeight  : int
        newWidth := max (minWidth, Rand.Int (0, 200))
        newHeight := max (minHeight, Rand.Int (0, 100))
        newX := Rand.Int (0, maxx  newWidth)
        newY := Rand.Int (0, maxy  newHeight)
        GUI.SetPositionAndSize (button, newX, newY, 
            newWidth, newHeight)
    end MoveButton
    
    button := GUI.CreateButton (100, 100, 0, "Move Button", 
        MoveButton)
    minHeight := GUI.GetHeight (button)
    minWidth := GUI.GetWidth (button)
    loop
        exit when GUI.ProcessEvent
    end loop

##Status Exported qualified.

This means that you can only call the function by calling GUI.SetPositionAndSize, not by calling SetPositionAndSize.
