Multiple Gui with GUICtrlSetOnEvent

[Pook]

Okay, I’ve been looking around the forums and reading the Help file. (I must not be looking in the wrong place, or it’s just one of those days).

I have a script that opens up a form ($Form_1) with buttons that users can pick from. If a user pick ‘button A’ then the main form ($Form_1) will close (using the func below). The new Gui form ($Form_2) opens fine, however none of the ‘buttons’ (GUICtrlSetOnEvent) commands will work under the new GUI. Does this make sense?

func _switch_Console1()

GUIDelete($Form_1)
_MainC() ; opens new ($Form_2)

endfunc

That makes sense to me.

You can't call a guisetonevent before a gui and it's controls are created, which is what you have essentially done.

Need to reset all guievents.

I have the GUICtrlSetOnEvent commands for the new GUI ($Form_2) inside the Func command (_MainC). (Not apart of $Form_1 code) How to you reset all guievents? (is that in the help file?

Not sure if it matters but I'm using the code below to on both forms to keep the GUI open

While 1
    sleep(10) 
WEnd

Maybe this will help clear things up

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
Opt("GUIOnEventMode", 1)
Global $gui, $gui2
Example1()
while WinExists("My GUI")
    sleep(100)
WEnd
Example2()
while WinExists("My GUI")
    sleep(100)
WEnd

; example 1
Func Example1()
   $gui=GUICreate("My GUI") ; will create a dialog box that when displayed is centered
    GUISetOnEvent($GUI_EVENT_CLOSE, "close")
    GUICtrlCreateButton("Hi",100,100,100,100)
    GUICtrlSetOnEvent(-1,"_pressed")
    GUISetState(@SW_SHOW) ; will display an empty dialog box
EndFunc   ;==>Example1

; example 2
Func Example2()
    Local $gui, $background, $pic, $basti_stay, $msg
    Local $sFile = "..\GUI\logo4.gif"
    $gui2 = GUICreate("My GUI", 400, 300)
        GUISetOnEvent($GUI_EVENT_CLOSE, "close2")
        GUICtrlCreateButton("Bye",100,100,100,100)
        GUICtrlSetOnEvent(-1,"_pressed")
    GUISetState(@SW_SHOW)
EndFunc   ;==>Example2

func close()
GUIDelete($gui)
EndFunc

func close2()
GUIDelete($gui2)
EndFunc

func _pressed()
    MsgBox(0,"", "Button Pressed")
EndFunc

This is what I'm doing and it doesn't work. I lost.

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
Opt("GUIOnEventMode", 1)
Global $gui, $gui2

_Example1()

; example 1
Func _Example1()
   $gui=GUICreate("My GUI") ; will create a dialog box that when displayed is centered
GUISetOnEvent($GUI_EVENT_CLOSE, "_exit")
    $Button = GUICtrlCreateButton("Hi",100,100,100,100)
    GUISetState(@SW_SHOW) ; will display an empty dialog box
    
    GUICtrlSetOnEvent($Button,"_pressed")
    
    While 1
    sleep(10) ; Comment this line out to see difference in cpu Usage.
    WEnd
    
EndFunc   ;==>Example1

; example 2
Func _Example2()
    Local $gui, $background, $pic, $basti_stay, $msg
    Local $sFile = "..\GUI\logo4.gif"
    $gui2 = GUICreate("My GUI", 400, 300)
        GUISetOnEvent($GUI_EVENT_CLOSE, "_exit")
        $Button2 = GUICtrlCreateButton("Bye",100,100,100,100)
           

    GUISetState(@SW_SHOW)
    
  GUICtrlSetOnEvent($Button2,"_exit")

func _pressed()
GUIDelete($gui)

EndFunc

func _exit()
GUIDelete($gui2)
exit

You should never stay in any event function longer than absolutely necessary. This works:

expandcollapse popup

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

Opt("GUIOnEventMode", 1)
Global $gui, $gui2

_Example1()

While 1
    Sleep(10) ; Comment this line out to see difference in cpu Usage.
WEnd

; example 1
Func _Example1()
    $gui = GUICreate("My GUI") ; will create a dialog box that when displayed is centered
    GUISetOnEvent($GUI_EVENT_CLOSE, "_exit", $gui)
    GUICtrlCreateButton("Hi", 100, 100, 100, 100)
    GUICtrlSetOnEvent(-1, "_pressed")
    GUISetState(@SW_SHOW) ; will display an empty dialog box
EndFunc   ;==>_Example1

; example 2
Func _Example2()
    $gui2 = GUICreate("My GUI", 400, 300)
    GUISetOnEvent($GUI_EVENT_CLOSE, "_exit", $gui2)
    GUICtrlCreateButton("Bye", 100, 100, 100, 100)
    GUICtrlSetOnEvent(-1, "_exit")
    GUISetState(@SW_SHOW)
EndFunc   ;==>_Example2


Func _pressed()
    ConsoleWrite("Debug:  _pressed() called" & @LF)
    GUIDelete($gui)
    _Example2()
EndFunc   ;==>_pressed

Func _exit()
    ConsoleWrite("Debug:  _exit() called" & @LF)
    GUIDelete($gui2)
    Exit
EndFunc   ;==>_exit

Okay... thanks for the background. So much to learn still!!

Really, as an alternative

I would use the original GUI, instead of deleting and remaking. Something like this.

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#Include <WinAPI.au3>
Opt("GUIOnEventMode", 1)
Global $gui


_Example1()

While 1
    sleep(10) ; Comment this line out to see difference in cpu Usage.
WEnd

; example 1
Func _Example1()
   $gui=GUICreate("My GUI") ; will create a dialog box that when displayed is centered
GUISetOnEvent($GUI_EVENT_CLOSE, "_exit", $gui)
    $Button = GUICtrlCreateButton("Hi",100,100,100,100)
    GUISetState(@SW_SHOW) ; will display an empty dialog box
    GUICtrlSetOnEvent($Button,"_pressed")
EndFunc   ;==>Example1

; example 2
Func _Example2()
    WinMove("My GUI","", 400, 300)
        $Button2 = GUICtrlCreateButton("Bye",100,100,100,100)
           GUICtrlSetOnEvent($Button2,"_exit") 
    GUISetState(@SW_SHOW)
EndFunc   ;==>Example2


func _pressed()
deletecontrols(-1,$gui)
_Example2()
EndFunc

func _exit()
exit 0
EndFunc

Func deletecontrols($last=-1,$guiname="")
    $aLastID = DllCall("user32.dll", "int", "GetDlgCtrlID", "hwnd", GUICtrlGetHandle($last))
    For $i = 0 To $aLastID[0]
        if WinGetHandle($guiname)=_WinAPI_GetParent(GUICtrlGetHandle($i)) Then
        GUICtrlDelete($i)
        EndIf
    Next
EndFunc
