lhw,

I would do it like this - try actioning the main GUI or the "Test" button while the child is visible: :)

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

$hGUI = GUICreate("Test", 500, 500)

$hButton_1 = GUICtrlCreateButton("Test", 10, 10, 80, 30)

$hButton_2 = GUICtrlCreateButton("Child", 10, 100, 80, 30)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $hButton_1
            MsgBox(0, "Button", "Pressed")
        Case $hButton_2
            ; Disable parent GUI
            GUISetState(@SW_DISABLE, $hGUI)
            ; Create child = adjust the coordinates to get it into the middle of the parent
            $hGUI_Child = GUICreate("Child", 200, 200, 150, 150, $GUI_SS_DEFAULT_GUI, $WS_EX_MDICHILD, $hGUI)
            GUISetState()
            ; Intercept attempts to move the child
            GUIRegisterMsg($WM_SYSCOMMAND, "On_WM_SYSCOMMAND")
            ; Wait for the child to close
            While 1
                If GUIGetMsg() = $GUI_EVENT_CLOSE Then ExitLoop
            WEnd
            ; Stop move message interception
            GUIRegisterMsg($WM_SYSCOMMAND, "")
            ; Re-enable main GUI
            GUISetState(@SW_ENABLE, $hGUI)
            ; Delete child
            GUIDelete($hGUI_Child)

    EndSwitch

WEnd

Func On_WM_SYSCOMMAND($hWnd, $Msg, $wParam, $lParam)
    ; Is it the child sending the message?
    If $hWnd = $hGUI_Child Then
        ; Is it a move message?
        If BitAND($wParam, 0xFFF0) = 0xF010 Then Return False ; $SC_MOVE
    EndIf

    Return $GUI_RUNDEFMSG
EndFunc

If you are not too familiar with GUIRegisterMsg, then I recommend the GUIRegisterMsg tutorial in the Wiki.

Please ask if you have any questions. :)

Also, have a look in my signature for _GUIDisable() to create a dark effect on the Main GUI.

@guinness : do you have some solution to handle this that drag n dropped item penetrate child GUI to main GUI when a input control on child GUI just hang over a input control on parent GUI and both input controls have DnD featrues,sorry my poor enlish, its just like the followings

#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
$MAINGUI = GUICreate("Program", 300, 200,  -1, -1, -1, $WS_EX_ACCEPTFILES)
$Input = GUICtrlCreateInput('', 56, 50, 137, 21)
GUICtrlSetState(-1, $GUI_DROPACCEPTED)
$MenuTool = GUICtrlCreateMenu('&Tool')
$subTool = GUICtrlCreateMenuItem('subtool', $MenuTool)

GUISetState(@SW_SHOW)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $GUI_EVENT_DROPPED
            If FileGetAttrib(@GUI_DragFile) == 'D' Then 
               GUICtrlSetData($Input, @GUI_DragFile)
            Else
                MsgBox(0, '', 'Only folder accepted')

                        GUISetState(@SW_ENABLE, $MainGUI)

                    If FileGetAttrib(@GUI_DragFile)== 'D' Then 
                        GUICtrlSetData($Input2, @GUI_DragFile)
                    Else
                        MsgBox(0, '', 'Only folder accepted')
                    EndIf
                EndSwitch
            WEND
    EndSwitch
WEnd
Func _GUIDisable($hHandle = -1, $iBrightness = 5, $hColor = 0x000000)
    If Not IsDeclared("Global_GUIDisable") Then Global $Global_GUIDisable = 0

    If $hHandle = -1 Then
        Local $hLabel = GUICtrlCreateLabel("", -99, -99, 1, 1)
        Local $aReturn = DllCall("User32.dll", "hwnd", "GetParent", "hwnd", GUICtrlGetHandle($hLabel))
        If @error Then Return SetError(1, 0 * GUICtrlDelete($hLabel), 0)
        GUICtrlDelete($hLabel)
        $hHandle = $aReturn[0]
    EndIf

    Local $iIsHWnd = IsHWnd($Global_GUIDisable)
    Switch $iIsHWnd
        Case 0
            Local $aWinGetPos = WinGetClientSize($hHandle)
            $Global_GUIDisable = GUICreate("", $aWinGetPos[0], $aWinGetPos[1], 0, 0, 0x80000000, 0x00000040, $hHandle)
            GUISetBkColor($hColor, $Global_GUIDisable)
            WinSetTrans($Global_GUIDisable, "", Round($iBrightness * (255 / 100)))
            GUISetState(@SW_SHOW, $Global_GUIDisable)
        Case 1
            GUIDelete($Global_GUIDisable)
    EndSwitch
    Return $Global_GUIDisable
EndFunc   ;==>_GUIDisable

BTW, i use GUICtrlSetState($Input, $GUI_NODROPACCEPTED) to avoid this happen when child GUI works,but i think its not a good way,

lhw,

Why not just make sure that there is nothing in the "main" input like this? :>

If StringInStr(FileGetAttrib(@GUI_DragFile), 'D') Then
    GUICtrlSetData($Input2, @GUI_DragFile)
    GUICtrlSetData($Input, "")
Else

Does that solve your problem? :unsure:

Hello,

Not trying to get out of line here, but would there be a way a child GUI could act the same way as an InputBox, MsgBox or FileOpenDialog?

When these functions are called with the parent GUI parameter defined, they do "block" the parent GUI; that would be the exact behavior I'd be looking for:

$GUI_parent=GUICreate("",500,400)
GUISetState()
InputBox("","As you can see, clicking the parent GUI isn't possible until you close this child window.","","",-1,-1,200,200,0,$GUI_parent)

If I have to use GUI_DISABLE and GUI_ENABLE, this will add a whole lot of "noise" to the script.

So I was wondering if there is another way... any ideas?

Regards,

footswitch

footswitch,

A couple of additional lines each time you create a child GUI does not seem very "noisy" to me. :)

Of course you can always filter the events to prevent those from the main GUI being actioned while the child is active - the Managing Multiple GUIs tutorial in the Wiki shows you how to go about this - but I would suggest that this might make your script even louder. ;)

@M23

Come to think about it, you're probably right.

I have functions inside other include files, and these functions create child GUIs. Evidently I need to pass the parent GUI's handle as a parameter.

So if I'm thinking straight, if I turn my child GUI's creations and deletions into their own functions, it won't be that "noisy" to include those lines inside of them.

Thank you for making me think :)

Sometimes that's all we need, right?
