Problem with placing child forms on the main form

9 posts in this topic

#1 ·  Posted (edited)

Hi,

I'm writing an application with a lot of controls, which for some reason shall be created on several child forms, and not on the main one. My problem: how to place a borderless child form as a part a big main window/form?

This works and is placed in the top left corner of the main window:

$ChildForm1 = GUICreate("", 1027, 83, 0,0, BitOR($WS_CHILD,$WS_TABSTOP,$WS_GROUP),0,$parent)

But when I create a second child form, it is always layered over the first one - although its coordinates are of course not set to 0,0.

How to place it below $ChildForm1?

Regards,

Martin

$bShow = False
$Frm_Main = GUICreate("Test Form", 300, 500, -1, -1)
GUISetBkColor(0x00FF00)
GUISetState()
$Frm_Child_1 = GUICreate("First Child", 300, 200, 0, 0, $WS_CHILD, -1, $Frm_Main)
$Btn_Disp = GUICtrlCreateButton("Toggle", 120, 90, 60, 30)
GUISetBkColor(0xFF0000)
GUISetState()
$Frm_Child_2 = GUICreate("Second Child", 300, 250, 0, 220, $WS_CHILD, -1, $Frm_Main)
GUISetBkColor(0x0000FF)


While 1
    $Msg = GUIGetMsg()
    Switch $Msg
        Case -3
            Exit
        Case $Btn_Disp
            If $bShow Then

                GUISetState(@SW_SHOW, $Frm_Child_2)
            EndIf
            $bShow = NOT $bShow
    EndSwitch
WEnd

Thank you so much - that was convincing!!

So I looked further into my code and found that I had a problem with the scope of my handle variable. So sorry for the question...

Before I open another silly thread:

My next problem is, that the tab key doesn't work in my child window. When the same form has the status $WS_POPUP instead of $WS_CHILD, I can browse though its controls - but when it's embedded in the main window, I lose this ability. Any idea for that?

Thanks a lot,

Martin

MartinGr,

Search the forum for $WS_EX_CONTROLPARENT. This style allows you to tab through the controls on child windows, but if I remember correctly has some side-effects on their "draggability". :)

You will find that using different background colors to check Windows and control positioning is a good method for finding if there is an issue in that regard or not.

Call it an oldtimers trick although it will make everything look ugly until you go back and remove the background colors.

George,

an oldtimers trick

As I use that trick too, it must be for "oldtimers"! :)

You are the one to whom I was refering my good man.

Besides I seem to recall giving you that same tip at one time.

Re: WS_EX_CONTROLPARENT

Greetings GEOSoft and Melba23

@MartinGr

you can prevent a child dialog with WS_EX_CONTROLPARENT style

from being dragged with a WM_NCHITTEST message handler.

some background reference to the issue with the WS_EX_CONTROLPARENT style for anyone else reading this post.

without that style, the child dialog is tabbed as one control.

see Trac ticket #1115 for the reason this style has the side effect

of making an AutoIt class child gui draggable.

Ticket #1115 (closed Bug: No Bug)

documentation for GuiCreate error

http://www.autoitscript.com/trac/autoit/ticket/1115

a modification of GEOSoft's example above

showing tabbing between controls on all three forms.

;#include <WinAPI.au3>
#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>

Opt('MustDeclareVars', 1)
Global $Frm_Child_1, $Frm_Child_2

_Main()

Func _Main()
    Local $bShow = False, $Msg
    Local $Frm_Main = GUICreate("Test Form", 300, 500, -1, -1)
    GUISetBkColor(0x00FF00)
    GUICtrlCreateButton("Main", 120, 470, 60, 30)

    $Frm_Child_1 = GUICreate("First Child", 300, 200, 0, 0, BitOR($WS_CHILD, $WS_TABSTOP), $WS_EX_CONTROLPARENT, $Frm_Main)
    Local $Btn_Disp = GUICtrlCreateButton("Toggle", 120, 90, 60, 30)
    GUISetBkColor(0xFF0000)
    GUISetState(@SW_SHOW, $Frm_Child_1)

    $Frm_Child_2 = GUICreate("Second Child", 300, 250, 0, 220, BitOR($WS_CHILD, $WS_TABSTOP), $WS_EX_CONTROLPARENT, $Frm_Main)
    GUISetBkColor(0x0000FF)

    GUICtrlCreateButton("Button1", 10, 20, 60, 30)
    GUICtrlCreateButton("Button2", 80, 20, 60, 30)
    GUICtrlCreateButton("Button3", 160, 20, 60, 30)
    GUICtrlCreateButton("Button4", 230, 20, 60, 30)

    GUIRegisterMsg($WM_NCHITTEST, "_WM_NCHITTEST") ;comment this line, and child forms with WS_EX_CONTROLPARENT style are draggable
    GUISetState(@SW_SHOW, $Frm_Main)


    While 1
        $Msg = GUIGetMsg()
        Switch $Msg
            Case -3
                Exit
            Case $Btn_Disp
                If $bShow Then
                    GUISetState(@SW_HIDE, $Frm_Child_2)
                Else
                    GUISetState(@SW_SHOW, $Frm_Child_2)
                EndIf
                $bShow = NOT $bShow
        EndSwitch
    WEnd
EndFunc

Func _WM_NCHITTEST($hWnd, $iMsg, $iwParam, $ilParam)
    #forceref $iMsg, $iwParam, $ilParam
    Switch Number($hWnd)
        Case Number($Frm_Child_1), Number($Frm_Child_2)
            ;Local $iCode = _WinAPI_DefWindowProc($hWnd, $iMsg, $iwParam, $ilParam)
            ;If $iCode = 2 Then Return 1
            ;Return $iCode
            Return 1
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc

I see fascists...

rover,

As usual you manage to cast light on some of the murkier areas of AutoIt coding. Thanks very much for that explanation. :)
