disable/grey out maximize/minimize/exit buttons

jennico · January 12, 2009

i have searched the forum without success.

how can i temporarily disable (grey out) the the three caption buttons (maximize/minimize/exit buttons) ?

i don't want to hide them, and i don't want to create the GUI in another style. i want to disable and grey out the three buttons.

here are lots of not working examples from the forum:

Run("notepad")
WinWait("Untitled - Notepad")
;WinWait("Unbenannt - Editor")
$calcHwnd = WinGetHandle("Untitled - Notepad")
;$calcHwnd = WinGetHandle("Unbenannt - Editor")

Global Const $SC_CLOSE = 0xF060
Global Const $SC_MINIMIZE = 0xF020
Global Const $SC_MAXIMIZE = 0xF030;
Global Const $SC_RESTORE = 0xF120

$menu = DllCall("user32.dll","hwnd","GetSystemMenu","hwnd", $calcHwnd, "int",0)
DllCall("user32.dll", "int", "RemoveMenu", "hwnd", $menu[0] , "int", $SC_MINIMIZE, "int", 0x0)
DllCall("user32.dll", "int", "RemoveMenu", "hwnd", $menu[0] , "int", $SC_MAXIMIZE, "int", 0x0)
DllCall("user32.dll", "int", "RemoveMenu", "hwnd", $menu[0] , "int", $SC_CLOSE, "int", 0x0)
DllCall("user32.dll", "int", "RemoveMenu", "hwnd", $menu[0] , "int", $SC_RESTORE, "int", 0x0)


#include <GUIConstants.au3>

;Global Const $SC_CLOSE        = 0xF060
Global Const $MF_GRAYED        = 0x00000001

$hGUI    = GUICreate('Test')
$Btn    = GUICtrlCreateButton('Exit', 100, 100, 70, 25)
GUISetState()

$hMenu = DllCall('user32.dll', 'int', 'GetSystemMenu', 'hwnd', $hGUI, 'int', 0)

GUISetStyle might do most of that... I'm not sure what to change it to though..

wraithdu · January 12, 2009

Use this option -

GUIEventOptions Change special event behavior or GUI function return values.

0 = (default) Windows behavior on click on Minimize,Restore, Maximize, Resize.

1 = suppress windows behavior on minimize, restore or maximize click button or window resize. Just sends the notification.

and handle the notifications yourself. It won't gray out the buttons, but it will give control of their behavior to you.

If you want the buttons greyed out and inactive there might be some clever way to do it, but the only way I know to make the window look disabled is to either use GuiSetSate(4) which will only last as long as you don't click on it, or to continually set focus to some other window which could be hidden and will produce some unpleasant effects.

So I would take a screen shot of the buttons on a disabled window, make a pic of them on a tiny popup window which is positioned over the real buttons, and keep it in the correct position somehow. That would give the look posibly and prevent the buttons from operating.

no no, i want them disabled (and greyed out) so that the user knows they are disabled. that's the question. seems easy but nobody knows.

complicated and you do not know how the buttons look like on the other machine (styles). Edited January 12, 2009 by jennico

get the new nvidia driver I have issues all the time with it disabling windows. close minimize and maximize tend to still work though.

jennico · January 12, 2009

when nvidia can do it, there must be a way for everyone.

btw: GuiSetState(4) does nothing to me. (4 = Window is enabled)?

Then try this, which will only stay looking deactivaqted until you click on it.

#include <GUIConstants.au3>
#include <WindowsConstants.au3>
$gui2 = GUICreate("dummy",100,60)
$iStyle1 = BitOr($WS_MAXIMIZEBOX, $WS_MINIMIZEBOX, $WS_CAPTION, $WS_POPUP, $WS_SYSMENU); Style with minimize box
$iStyle2 = BitOr( $WS_CAPTION, $WS_POPUP, $WS_SYSMENU); Style without minimize box

$gui = GUICreate('', 200, 200, -1, -1, $iStyle1)
$bt1 = GUICtrlCreateButton('Click me to enable', 5, 5, 120, 25)
$bt2 = GUICtrlCreateButton('Click me to disable', 5, 35, 120, 25)

GUISetState(4)


While 1
    $gm = GUIGetMsg()
    Switch $gm
        Case $GUI_EVENT_CLOSE
            ExitLoop
        Case $bt1
           ;GUISetStyle($iStyle1)
            GUISetState()
        Case $bt2

    EndSwitch
WEnd

wraithdu · January 12, 2009

This is as close as I can get. If you choose a window style with the minimize / maximize boxes, you cannot gray them out. You can remove the menu item, which effectively disables their function, but they will not look grayed out.

#include <guimenu.au3>
#include <windowsconstants.au3>

$gui = GUICreate("Disable exit button", 400, 400, -1, -1, BitOR($WS_SYSMENU, $WS_CAPTION))
$close = GUICtrlCreateButton("Close", 10, 10, 50, 30)

GUISetState()

$menu = _GUICtrlMenu_GetSystemMenu($gui)
_GUICtrlMenu_EnableMenuItem($menu, $SC_CLOSE, 1, False)

Do
    $msg = GUIGetMsg()
    Switch $msg
        Case $close
            $msg = -3
    EndSwitch
Until $msg == -3

This is a crude example of the way I suggested just for the record.

#include <GUIConstants.au3>
#include <WindowsConstants.au3>
#include <screencapture.au3>
$iStyle1 = BitOr($WS_MAXIMIZEBOX, $WS_MINIMIZEBOX, $WS_CAPTION, $WS_POPUP, $WS_SYSMENU); Style with minimize box
$iStyle2 = BitOr( $WS_CAPTION, $WS_POPUP, $WS_SYSMENU); Style without minimize box

$gui = GUICreate('', 200, 200, 400,400, $iStyle1)
$bt1 = GUICtrlCreateButton('Click me to enable', 5, 5, 120, 25)
$bt2 = GUICtrlCreateButton('Click me to disable', 5, 35, 120, 25)

GUISetState(4)
sleep(100);in case window doesn't show straight away
_ScreenCapture_Capture(@scriptdir & "\disabled1.bmp",400+134,405,400+202,405+21)
$g2 = GUICreate("Dummy",202-134,21,400+134,405,$WS_POPUP)
GUICtrlCreatePic(@scriptdir & "\disabled1.bmp",0,0,202-134,21)
GUISetState()
winsetontop($g2,"",1)
;GUISwitch($gui)
GUIRegisterMsg($WM_MOVE,"moved")
While 1
    $gm = GUIGetMsg()
    Switch $gm
        Case $GUI_EVENT_CLOSE
            ExitLoop
        Case $bt1
            WinSetState($g2,"",@SW_HIDE)
           ;GUISetStyle($iStyle1)
            GUISetState()
        Case $bt2
            
            WinSetState($g2,"",@SW_SHOW)
           ;GUISetStyle($iStyle2)
    EndSwitch

     
     
WEnd

Func moved()
    $wp = WinGetPos($gui)
    WinMove($g2,"",$wp[0]+134,$wp[1] + 5)
    
EndFunc

@martin: very clever !!!! (but they are not grey !)

i've googled it, nothing to find. so i think:

- close button can be disabled (see above examples).

- maximize button can be disabled by style (see above).

- minimize button cannot be disabled.

- minimize and maximize button can be hidden by style, close button not.

Double click on the titlebar :-P, Also, it's all gray in a rectangle. the space between the buttons is gray, and in my xp style, the corners where they are rounded.

Edit, you can also still edit from the taskbar.

Well yes, it was only for a bit of fun. It needs more work to make it useful but I've exhausted my interest in it now

Someone once gave me this when I asked for help on the matter of disabling the minimize button.

I changed it a bit and there is something unusual, about it, check it out. If you remove the maximize from style 2 and press to disable they both disappear.

#include <GUIConstants.au3>
#include <WindowsConstants.au3>

$iStyle1 = BitOr( $WS_MINIMIZEBOX, $WS_CAPTION, $WS_SYSMENU); Style with minimize box
$iStyle2 = BitOr($WS_MAXIMIZEBOX, $WS_CAPTION, $WS_SYSMENU); Style without minimize box

$gui = GUICreate('', 200, 200, Default, Default, $iStyle1)
$bt1 = GUICtrlCreateButton('Click me to enable', 5, 5, 120, 25)
$bt2 = GUICtrlCreateButton('Click me to disable', 5, 35, 120, 25)
GUISetState()

While 1
    $gm = GUIGetMsg()
    Switch $gm
        Case $GUI_EVENT_CLOSE
            ExitLoop
        Case $bt1
            GUISetStyle($iStyle1)
        Case $bt2
            GUISetStyle($iStyle2)
    EndSwitch
WEnd

so i have to correct my final conclusions:

- close button can be disabled (see above examples).

- maximize button can be disabled by style BitOr($WS_MINIMIZEBOX, $WS_CAPTION, $WS_SYSMENU)

- minimize button can be disabled by style BitOr($WS_MAXIMIZEBOX, $WS_CAPTION, $WS_SYSMENU)

- both minimize and maximize button cannot disabled together.

- both minimize and maximize button can be hidden by style, close button not.

i wonder why MS forgot that feature .....

jennico · January 13, 2009

i have a small linguistic problem:

many members here and msdn itself spell it gray out ($MF_GRAYED).

i think it has to be grey out (from the color grey).

is gray synonymous to grey or does it mean something different?

is gray allowed ?

Gray is US English afaik, and yes it's allowed. Same with color which is US English whereas I use colour (and so does ResNullius).
