Trap the ENTER key via GUISetAccelerators() when in EventMode

I have a GUI with several input boxes and I want to trap the ENTER key so I can call handlers for each one.
 
However, when I put in a HotKeySet() to trap the ENTER key, it traps it OK, but I also get traps when I press the ENTER key anywhere else on my desktop, no matter what GUI has focus, so I changed the code to use GUISetAccelerators().  I cannot see how to attach a handler for the ENTER key for each of my input controls.
 
My real script uses event mode (Opt("GUIOnEventMode", 1)), so that's what I'm using in my test code.
 
Here is my test code:
#NoTrayIcon
#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_UseUpx=n
#AutoIt3Wrapper_Au3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****

#include <GUIConstantsEx.au3>
#include <StructureConstants.au3>
OnAutoItExitRegister("ExitStageLeft")

Opt("GUICloseOnESC", 1)
Opt("GUIEventOptions", 1)
Opt("GUIOnEventMode", 1) ;; <=====
Opt("WinTitleMatchMode", 1)
Opt('MustDeclareVars', 1)

Global $hWnd_list1, $hWnd_input1, $hGUI, $sWinTitle
Global $iID_list1, $iID_input1

_Main()
Exit (1)

Func _Main()

    $sWinTitle = "ENTER key trap test"
    $hGUI = GUICreate($sWinTitle, 500, 230)

    GUICtrlCreateButton("Test", 5, 5, 50, 25)
    $iID_input1 = GUICtrlCreateInput("input1", 70, 5, 100, 25)
    $hWnd_input1 = GUICtrlGetHandle($iID_input1)

    $iID_list1 = GUICtrlCreateEdit("list1", 10, 40, 475, 190)
    $hWnd_list1 = GUICtrlGetHandle($iID_list1)
    GUICtrlSetData($iID_list1, "abcdefghijklmnopqrstuvwxyz" & @CRLF, 1)

    ConsoleWrite("+++: $iID_list1  = " & $iID_list1 & @CRLF)
    ConsoleWrite("+++: $iID_input1 = " & $iID_input1 & @CRLF)

    GUISetState()

    GUICtrlSetOnEvent($iID_list1, "handle_List1")
    GUICtrlSetOnEvent($iID_input1, "handle_Input1")

    GUISetOnEvent($GUI_EVENT_CLOSE, 'ExitStageLeft')

    Local $aAccelKeys[2][2]
    $aAccelKeys[0][0] = "{ENTER}"
    $aAccelKeys[0][1] = $iID_input1
    $aAccelKeys[1][0] = "{ENTER}"
    $aAccelKeys[1][1] = $iID_list1

    GUISetAccelerators($aAccelKeys)

    While (1)
        Sleep(250)
    WEnd
EndFunc   ;==>_Main

Func ExitStageLeft()
    Exit (0)
EndFunc   ;==>ExitStageLeft

Func handle_Input1()
    ConsoleWrite("+++: handle_Input1() entered" & @CRLF)
EndFunc   ;==>handle_Input1

Func handle_List1()
    ConsoleWrite("+++: handle_List1() entered" & @CRLF)
EndFunc   ;==>handle_List1

You can't use the same hotkey or accellerator for 2 controls at the same time.

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.

Thank you very much!  Using a dummy control to handle the ENTER key only when it's pressed somewhere on the main GUI did the trick.  I'll add this little gem to my collection of tips and workarounds.

I ran into a problem implementing LarsJ's code.  If I don't handle the ENTER key for a certain control and I want that control to receive an actual ENTER key event, the ENTER key is ignored.  If I Send("{ENTER}") to those controls, I get into an infinite loop.

Here is my handler code:

Func handle_ENTERKey($iCtrl)
    local $handled = False

    Switch $iCtrl
        Case $iID_list1
            ConsoleWrite("+++: handle_List1() entered" & @CRLF)
            $handled = true
        Case $iID_input1
            ConsoleWrite("+++: handle_Input1() entered" & @CRLF)
            ;;$handled = true
    EndSwitch

    if (not $handled) Then
        Send("{CRLF}")
    EndIf
EndFunc   ;==>handle_ENTERKey
 

I call this code from the dummy control's handle_ENTER() handler, with $iCtrl as its parameter..

If I handle the event, everything is OK, but if I want the ENTER key to go into my list control, sending a "{ENTER}" key gets me into a loop because that will call the ENTER key handler again.

How can I pass the ENTER key to controls I don't want to do any special handling for?

you should disable accelerators,  ControlSend {ENTER} to control with focus and reenable accelerators again

....have a look to link I posted above ....

also look to post >#8 of the above topic for an explanation

Right-o.  I changed my Enter key handler to look something like this:

Func handle_ENTERKey($iCtrl)
    local $handled = False

    Switch $iCtrl
        Case $iID_list1
            ConsoleWrite("+++: ENTER while on list1" & @CRLF)
            ;;  $handled = true
        Case $iID_input1
            ConsoleWrite("+++: ENTER while on Input1" & @CRLF)
            $handled = true
    EndSwitch

    if (not $handled) Then
        GUISetAccelerators(0)
        ConsoleWrite("+++: sending {ENTER} to control ID " & $iCtrl & @CRLF)
        Send("{ENTER}")
        GUISetAccelerators($AccelKeys) ;
    EndIf
EndFunc   ;==>handle_ENTERKey

Works like I want it to.  Thanks, PincoPanco

      GUIsetaccelerators doesn't work for Ctrl+Shift+0 (zero)
      By therks
      So I'm working on an application and I've hot keyed all the numbers, and for some reason this particular combination doesn't work. All the other numbers with Ctrl+Shift work fine, and all other combinations of modifiers work with 0. Has anyone else encountered this? It's very strange. 
      Guicreate('', 300, 300) $button = GUICtrlCreateButton('Button', 0, 0) Dim $accel = [ [ '^+0', $button ] ] GUIsetaccelerators($accel) Do $gm = guigetmsg()  If $gm = $button then msgbox(0,'','test') Until $gm = - 3 Sorry for the ugly code, i typed this up on my phone. 😅

      Pass unused Accelerator keys back to the system
      By AndyS19
      I have a script that traps ^A and ^C accelerator keys via the GUISetAccelerators() function, and in the key handlers, I check to see if the focus is on the control that I want the keys to operate on.
      However, when I see that I'm not on that control, I want to pass the ^C and ^A back to the system so I can copy and past data on other controls.
      Here is my test script.  I have it applying ^A and ^C only to the ListView control.  When I put focus on the Input control, I want to be able to copy and paste normally.

      Help Needed with GUISetAccelerators
      By vindicta
      Hello everyone,
      I am trying to setup a GUI accelerator to close the utility as soon as esc is pressed.  It works fine with hotkey but I want to make sure that the utility only exits if its window was active when esc was pressed. My utility has 2 buttons, Backup and Restore.
      The exit function checks if the button clicked was Backup or Restore and then displays an error message accordingly.
      If pressed backup, $button = 1
      if pressed restore, $button = 2
      the value of $button is set inside backup() or restore() functions
      Opt("GUIOnEventMode", 1) Opt("GUICoordMode", 1) $Form1 = GUICreate("Form1", 419, 124, 238, 194, $WS_DLGFRAME) $B_backup = GUICtrlCreateButton("Backup", 48, 40, 145, 41) $B_restore = GUICtrlCreateButton("Restore", 224, 40, 145, 41) ;================ > HotKeySet('{ESC}', "terminate") GUICtrlSetOnEvent($B_backup, "Backup") GUICtrlSetOnEvent($B_restore, "Restore") GUISetState(@SW_SHOW) Dim $accelKey[1][2] = [["{ESC}", terminate()]] GUISetAccelerators($accelKey) While 1     Switch GUIGetMsg()         Case $GUI_EVENT_CLOSE             Exit     EndSwitch WEnd  
      Exit function:
      func terminate() Do     $msg = GUIGetMsg() Until $msg <> 0 While 1         If $button = 1 Then             ProcessClose("robocopy.exe")             MsgBox(16, "Abort!", "Backup Aborted!")             exit         ElseIf $button = 2 Then             ProcessClose("robocopy.exe")             MsgBox(16, "Abort!", "Restore Aborted!")             exit         Else             While 1                 For $i = 3 To 1 Step -1                     SplashTextOn("Closing Utility...", $i, 130, 54, -1, -1, 0, "Calibri", "", 900)                     Sleep(1000)                 Next                 ExitLoop             WEnd             SplashOff()             Exit Endif WEnd What am I doing wrong here? The utility closes as soon as it launches with Splash text.
