On GUI Event Mode, how to identify different event(s) for a control

5 posts in this topic

I have enabled GUI On Event Mode "Opt("GUIOnEventMode", 1)",

I have also declared a event handler for a Control.

When the handler is called, how to identify the event or events for that particular control ?

For example, I have a listbox, for that I have registered a handler, inside the handler I have to identify the EVENTS (like SELCHANGE, DBL_CLICKED, etc.,)

how to identify ?

Hi AdmiralAlkex,

My question is not about GUIRegisterMsg(), it is about GUICtrlSetOnEvent()

I'm with the Admiral on this. This can be done more easily with Guiregistermsg()

#include <GuiComboBoxEx.au3>
#include <GuiImageList.au3>
#include <GUIConstants.au3>
#include <WindowsConstants.au3>
Opt('MustDeclareVars', 1)


_Main()

Func _Main()
    Global $msg, $hGUI, $hImage, $combobox, $button, $sText
    
    ; Create GUI
    $hGUI = GUICreate("ComboBoxEx Get Text with Icon", 400, 300)
    $combobox = _GUICtrlComboBoxEx_Create($hGUI, "", 2, 2, 394, 100)
    GUISetState()

    $button = GUICtrlCreateButton("Get text", 50, 150, 100, 20)
    $hImage = _GUIImageList_Create(16, 16, 5, 3)
    For $x = 0 To 20
        _GUIImageList_AddIcon($hImage, @SystemDir & "\shell32.dll", $x)
    Next
    _GUICtrlComboBoxEx_SetImageList($combobox, $hImage)
    _GUICtrlComboBoxEx_InitStorage($combobox, 150, 300)
    _GUICtrlComboBoxEx_BeginUpdate($combobox)

    For $x = 0 To 20
        _GUICtrlComboBoxEx_AddString($combobox, StringFormat("%03d : Random string", Random(1, 200, 1)), $x, $x)
    Next

    _GUICtrlComboBoxEx_EndUpdate($combobox)
    GuiRegisterMsg($WM_COMMAND,"MY_WM_COMMAND")
Global $fComboFocused = False
    While 1
        $msg = GUIGetMsg()
        Switch $msg
            Case $GUI_EVENT_CLOSE
                ExitLoop
            Case $button
                _GUICtrlComboBoxEx_GetItemText($combobox, _GUICtrlComboBoxEx_GetCurSel($combobox), $sText)
                MsgBox(4160, "Information", "Edit Text: " & $sText)
        EndSwitch
    WEnd
EndFunc   ;==>_Main

 Func MY_WM_COMMAND($hWnd, $msg, $wParam, $lParam)
    Local $nNotifyCode = _HiWord($wParam)
    Local $nID = _LoWord($wParam)
 ; Local $hCtrl = $lParam

    Switch $lParam
    Case $combobox
            Switch $nNotifyCode
            Case $CBN_SETFOCUS
                ConsoleWrite("Focus"&@crlf)
        Case $CBN_KILLFOCUS
            ConsoleWrite("Kill Focus"&@crlf)
        Case $CBN_SELCHANGE
            ConsoleWrite("Selection Changed"&@crlf) 
        Case $CBN_DROPDOWN
            ConsoleWrite("Drop Down"&@crlf)
                
        EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc ;==>MY_WM_COMMAND

Func _HiWord($x)
    Return BitShift($x, 16)
EndFunc ;==>_HiWord

Func _LoWord($x)
    Return BitAND($x, 0xFFFF)
EndFunc ;==>_LoWord

Hi AdmiralAlkex,

My question is not about GUIRegisterMsg(), it is about GUICtrlSetOnEvent()

No, you asked how to identify different events, and I answered that. See the example for whatever control you're using in the "User Defined Function Reference" section in the helpfile.
