Restrict GUI Resize with Minimal Dimensions

4 posts in this topic

Hello... If someone knows if the feature exists or an approach to be able to set the minimal dimensions of a GUI Window for resizing?

Basically I have created a GUI Window set to 800x600 and given the user the ability to resize bigger and even fullscreen it, however I would like to restrict the user from resizing it any smaller than 800x600. Any assistance would be greatly appreciated.

Thanks!

DarkBoost,

Easy when you know how! ;)

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Global $GUIMINWID = 300, $GUIMINHT = 100;set your restrictions here
Global $GUIMAXWID = 800, $GUIMAXHT = 500

GUIRegisterMsg($WM_GETMINMAXINFO, "WM_GETMINMAXINFO")

$hGUI = GUICreate("Test", 500, 500, -1, -1, BitOR($GUI_SS_DEFAULT_GUI, $WS_MAXIMIZEBOX, $WS_SIZEBOX))

GUISetState()

$aPos = WinGetPos($hGUI)

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_MAXIMIZE
            ;WinMove($hGUI, "", $aPos[0], $aPos[1], $aPos[2], $aPos[3])
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Func WM_GETMINMAXINFO($hwnd, $Msg, $wParam, $lParam)
    $tagMaxinfo = DllStructCreate("int;int;int;int;int;int;int;int;int;int", $lParam)
    DllStructSetData($tagMaxinfo, 7, $GUIMINWID) ; min X
    DllStructSetData($tagMaxinfo, 8, $GUIMINHT) ; min Y
    DllStructSetData($tagMaxinfo, 9, $GUIMAXWID ); max X
    DllStructSetData($tagMaxinfo, 10, $GUIMAXHT ) ; max Y
    Return 0
EndFunc   ;==>WM_GETMINMAXINFO

All clear? :)

I have been using this example in a few scripts... works great but unsure how to use this for a non AutoIT window, eg. say i want to restrict Notepad from being resized!?
