Hello there fellas!

I've stumbled upon a simple problem: I have a parent GUI, and 3 children, but when I hit a "Hide" button on a child GUI, the whole application shuts down...how can I prevent this from happening? (I only want the particular child to close)

Thanks in advance ;)

With-out short script which can duplicate the problem I would need to get my crystal ball, but it's broken at this time.

I'm sorry to hear that, I hope you get it fixed soon, in the meantime here's the code...

If $msg = $Button_1 Then GuiSetState( @SW_SHOW, $child_[1])
    If $msg = $Button_2 Then GuiSetState( @SW_SHOW, $child_[2])
        If $msg = $Button_3 Then GuiSetState( @SW_SHOW, $child_[3])
            If $msg = $othermenuitem Then GUISetState( @SW_SHOW, $child_[4])
            If $msg = $Button_13 Then Winclose("Section1") 
            If $msg = $Button_14 Then Winclose("Section2")
            If $msg = $Button_15 Then Winclose("Shutdown")

Example: when I hit "button_15" it closes the whole GUI instead of only the GUI with the title "Shutdown" ;)

Still guessing here, so why not use GuiDelete($WinHandle)

Assuming you created the gui window and captured the handle

I.E.

$WinHandle = GuiCreate("ShutDown")

My guess as to why this happens is that WinClose probably sends $GUI_EVENT_CLOSE to the window. And because you probably have one whole loop and GUIGetMsg returns messages for all windows, your While 1 ... WEnd loop picks this p and assumes it is for the parent GUI, therefore closes it and closes the children.

Thank you!! That was driving me nuts. I just reread up on the GUIGetMsg(1). Before I couldn't understand it's usage. Now I see more how it's setting the array.

With this method there is no way to create the child window "after the fact." I'm just thinking for future usage. Just curious and trying to understand all the ins-and-outs.

Addition:

Thank you furthermore, this has made me understand and use GUIState's optional parameter. I'm really understanding the GUIGetMsg more now. It's pretty sweet.

after the fact

#include <GUIConstants.au3>

;Initialize variables
Global $IniFile, $ChildWin
Global $GUIWidth = 250
Global $GUIHeight = 250


$ParentWin = GUICreate("Parent GUI", $GUIWidth, $GUIHeight)

$ParentWin_Pos = WinGetPos($ParentWin, "")

$btn = GUICtrlCreateButton("Child", 50, 50, 80, 25)
GUISetState(@SW_SHOW)


While 1

    $msg = GUIGetMsg()
    If $msg = -3 And WinActive($ParentWin) Then Exit
    If $msg = $btn Then MakeChild()

WEnd


Func MakeChild()

    $ChildWin = GUICreate("Child GUI", $GUIWidth, $GUIHeight, $ParentWin_Pos[0] + 100, $ParentWin_Pos[1] + 100, -1, -1, $ParentWin)
    GUISetState(@SW_SHOW)
    
    While 2
        $msg2 = GUIGetMsg()
        If $msg2 = -3 And WinActive($ChildWin) Then
            GUIDelete($ChildWin)
            ExitLoop
        EndIf
    WEnd
EndFunc   ;==>MakeChild

I just butchurd the prev code.... there are many ways to do this

I looked through GUIConstantsEx.au3. So the -3 means $GUI_EVENT_CLOSE? This is so much shorter than typing that out, but I just wanted to verify that it means that. I really want to understand the meaning of everything you wrote out. You and xCal provided GREAT examples! These should be in the help file, in my opinion.

OK ..

when you download the inventor game the source is included .. but here's the solution

Lets say you create a menu with special thanks to other people who helped you and we call it credit

include <GUIConstants.au3>

Opt("TrayMenuMode", 1) 
Opt("GUIResizeMode", 1)
AutoItSetOption("TrayIconHide", 1)


$Parent = GuiCreate("Parent" , 250, 150)
$Filemenu = GUICtrlCreateMenu ("&File")
$Helpmenu = GUICtrlCreateMenu ("&?")
$FilemenuExit  = GUICtrlCreateMenuitem ("&Exit", $filemenu)
$HelpmenuCredits = GUICtrlCreateMenuitem ("&Credit", $helpmenu)
GUICtrlCreateLabel ("Nothing here", 20,40,150,20)
GUICtrlCreateLabel ("Select menu ? and click credits", 20,60,150,20)
GUISetState()

Func Credits ()
    GuiSetState (@SW_DISABLE, $Parent)
    $Child = GuiCreate("Say Thnx",200,80,-1,-1)
    $ChildFilemenu = GUICtrlCreateMenu ("&File")
    $ChildFilemenuExit  = GUICtrlCreateMenuitem ("&Exit", $ChildFilemenu)
    GUICtrlCreateLabel ("i would like to say thanks to Emiel", 20,40)
    GUISetState(@SW_SHOW, $Child)
    
    While 2 
        $msgchild = GUIGetMsg ()
        If $msgchild = $GUI_EVENT_CLOSE then
            ExitLoop
        EndIf
        Select
            case $msgchild = $ChildFilemenuExit
                Exitloop 
        EndSelect
    Wend
    
    GuiDelete ($Child)
    GuiSetState (@SW_ENABLE, $Parent)
    GuiSetState (@SW_RESTORE, $Parent)
    GuiSwitch ($Parent)
EndFunc

While 1 
    $msg = GUIGetMsg ()
        If $msg = $GUI_EVENT_CLOSE then
            Exit
        EndIf
        Select
            case $msg = $FilemenuExit
                exit
            case $msg = $HelpmenuCredits
                Credits ()
        Endselect
WEnd

:whistle: Yes definite props to those who give me such awesome direction! Learning the syntax of and using autoit is/has been wonderful. Xcal, Valuater, and yourself so far have been so helpful in me understanding how to do child window close (and more as a result).

Why would you suggest this method over Valuater's or SlimShady's?
