Case for Button Reassigns when Deleted


Recommended Posts

Hello,

I am trying to create a GUI that deletes and adds controls as users interact with it. The problem is that when a control is deleted, it's original Case statement is assigned to the next available control under the same class.

In the example below, you will see that once the 1st two buttons are deleted and the 3rd and 4th buttons are created, clicking button 3 does the same thing that buton 1 was assigned to.

Any suggestions on fixing the code or using an alternate method? I would rather not have to create a new GUI if I don't have to.

Thanks

#include <GUIConstants.au3>

$hGUI = GUICreate (Default, Default, 500, 100)

$idButton1 = GUICtrlCreateButton ("Button1", 10, 10, 50, 40)
$idButton2 = GUICtrlCreateButton ("Button2", 50, 40, 50, 40)

GUISetState (@SW_SHOW, $hGUI)

Local $idDummy
Local $idButton3
Local $idButton4

While 1
    $idMsg = GUIGetMsg()
    Switch $idMsg
        Case $GUI_EVENT_CLOSE
            ExitLoop
        Case $idButton1
            GUICtrlDelete ($idButton1)
            GUICtrlDelete ($idButton2)
            $idButton3 = GUICtrlCreateButton ("Button3", 20, 20, 50, 40)
            $idButton4 = GUICtrlCreateButton ("Button4", 60, 30, 50, 40)
            GUICtrlSetState ($idButton4, $GUI_DISABLE)
            Msgbox (0, "", "this is the original case function")
        Case $idButton2
            GUICtrlDelete ($idButton1)
            GUICtrlDelete ($idButton2)
            $idButton3 = GUICtrlCreateButton ("Button3", 20, 20, 50, 40)
            $idButton4 = GUICtrlCreateButton ("Button4", 60, 30, 50, 40)
            $idCombo = GUICtrlCreateCombo ( 80, 40, 100, 40)
            GUICtrlSetState ($idButton4, $GUI_DISABLE)
        Case $idButton3
            GUICtrlSetState ($idButton4, $GUI_ENABLE)
    EndSwitch
WEnd

Perhaps building all the controls first, then hiding the ones you don't want to show at start up? Then you can hide/unhide them as you interact with the GUI. Use GUICtrlSetState to hide/unhide them.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

Using the OnEventMode should work without this behaviour: 

#include <GUIConstants.au3>

Opt("GUIOnEventMode", 1) ;0=disabled, 1=OnEvent mode enabled

$hGUI = GUICreate(Default, Default, 500, 100)
GUISetOnEvent($GUI_EVENT_CLOSE, '_Exit')
$idButton1 = GUICtrlCreateButton("Button1", 10, 10, 50, 40)
GUICtrlSetOnEvent(-1, 'Button1Clicked')
$idButton2 = GUICtrlCreateButton("Button2", 80, 10, 50, 40)
GUICtrlSetOnEvent(-1, 'Button2Clicked')

GUISetState(@SW_SHOW, $hGUI)

Local $idDummy
Local $idButton3
Local $idButton4
Local $iTop = 10

WinWaitClose($hGUI)
_Exit

Func Button1Clicked()
    $iTop += 30
    GUICtrlDelete($idButton1)
    GUICtrlDelete($idButton2)
    $idButton3 = GUICtrlCreateButton("Button3", 10, $iTop, 50, 40)
    GUICtrlSetOnEvent(-1,'Button3clicked')
    $idButton4 = GUICtrlCreateButton("Button4", 80, $iTop, 50, 40)
    GUICtrlSetOnEvent(-1, 'Button4clicked')
    GUICtrlSetState(-1, $GUI_DISABLE)
    MsgBox(0, @GUI_CtrlId, "this is the original case function")
EndFunc   ;==>Button1Clicked

Func Button2Clicked()
    $iTop += 30
    GUICtrlDelete($idButton1)
    GUICtrlDelete($idButton2)
    $idButton3 = GUICtrlCreateButton("Button3", 10, $iTop, 50, 40)
    GUICtrlSetOnEvent(-1, 'Button3clicked')
    $idButton4 = GUICtrlCreateButton("Button4", 80, $iTop, 50, 40)
    GUICtrlSetOnEvent(-1, 'Button4clicked')
    GUICtrlSetState(-1, $GUI_DISABLE)
    $idCombo = GUICtrlCreateCombo(80, 40, 100, 40)
EndFunc   ;==>Button2Clicked

Func Button3clicked()
    GUICtrlSetState($idButton4, $GUI_ENABLE)
    MsgBox(0,@GUI_CtrlId,'Button 3')
EndFunc   ;==>Button3clicked

Func Button4clicked()
    GUICtrlSetState($idButton4, $GUI_ENABLE)
    MsgBox(0,@GUI_CtrlId,'Button 4')
EndFunc   ;==>Button3clicked

Func _Exit()
    Exit
    GUIDelete($hGUI)
EndFunc   ;==>_Exit
