 ; This snippet will show you a "hack" that you can use in GUI OnEvent mode in AutoIt
 ; With this hack you can create fake/pseudo events for a control in a OnEvent "handler"
 ; function which is registered with multiple controls.

 ; Usually you can get around this by using a unique function for every control
 ; but I like to use a single function that I use as a handler for a group of related
 ; controls. Looks neat and organized :)

 ; Let's get started!

 ; Include the important stuff
 #include <AutoItConstants.au3>
 #include <GUIConstantsEx.au3>
 #include <WindowsConstants.au3>

 Opt("GUIOnEventMode", 1)

 ; This function will create the GUI and make it visible
 Func CreateGUI()
 	GUICreate("Example", 60, 60)
 	; Functions with parameters will not be called, unless all of their parameters are optional (undocumented)
 	GUISetOnEvent($GUI_EVENT_CLOSE, HandleGUI)
 	Global $idToggleButton = GUICtrlCreateButton("", 5, 05, 50, 50)
 	GUICtrlSetOnEvent($idToggleButton, HandleGUI)
 EndFunc

 ; This is our most important piece of code, the Handler function which handles
 ; any events generated by the GUI!
 Func HandleGUI($iCtrlID = Default)
 	; As mentioned previously, when a function is called by AutoIt's OnEvent handler,
 	; the optional parameters are NOT defined at all! So their default values are meaningless
 	; Therefore we can use IsDeclared to see if a parameter is declared, effective way to know
 	; if it was called by AutoIt's OnEvent handler.
 	;
 	; The switch expression is a ternary operation, it first checkes if $iCtrlID is defined,
 	; then if it is declared locally, the expression is evaluated to $iCtrlID's value. This
 	; would be the case when a psedo/fake event has been generated by the script manually
 	;
 	; If it was called by AutoIt, then the expression would evaluate to @GUI_CtrlID
 	;
 	; This allows for seamless integration with the code, you won't have to use ControlClick to
 	; create a mouse press or something similar!
 	Switch (IsDeclared("iCtrlID") = $DECLARED_LOCAL ? $iCtrlID : @GUI_CtrlId)
 		Case $GUI_EVENT_CLOSE
 			Exit
 		Case $idToggleButton
 			Local Static $bOn = True
 			If $bOn Then
 				GUICtrlSetData($idToggleButton, "Off")
 				$bOn = False
 			Else
 				GUICtrlSetData($idToggleButton, "On")
 				$bOn = True
 			EndIf
 	EndSwitch
 EndFunc

 ; A practical use case:
 ; Often when there is a button which toggles/switches between values, the default value will have
 ; to be repeated when creating the control, this is fine for small things but is a good way to do
 ; if you have something more that needs to be done. This is just a simple example of a button which
 ; toggles between On and Off. The speciality is that those values will not be repeated in the code :)
 ;
 ; This is not very easy to read or as simple as setting the value of the button to the default state
 ; during the creation of the GUI, but it is a good practise that helps you avoid replicating text

 CreateGUI()

 HandleGUI($idToggleButton) ; This will generate a fake event which will trigger the same action as clicking on the button

 GUISetState() ; Show the GUI

 While True
 	Sleep(10)
