Given the a TGadget object as the field to a type. Is it possible get type which contains that field so that a method can be called automatically?

Type My
Field test:TGadget
Method Update()
x=x+1
End Method
End Type

.....
local MyObj:my=New my

If ( EventSource()=MyObj.Test )
MyObj.Update
End If
^
|
I want the above To be automatic
Something like EventSource().Update

Is this in anyway possible?

If you replace My with an actual object, then this is how it works at the moment.
But if you let it be My (the type itself), you can't access field / method, only globa l/ const / function.

Sorry, I did mean the my was the object and I have updated the code in the first post accordingly (hopefully).

The idea is that that "my" is a type that includes a label, text box and slider with methods to update the text based on the slider position and update the slider position based on the text input. The GUI will be a collection of these (around 30). The case statement looking at each text box and slider is huge and I thought there must be a better way to do this.

If the eventsource() is MyObj.Test (i.e. the slider) can I find MyObj so that I can call the MYObj method to update the associated text box?

why dont you just create a list

Type My
	Field test:TGadget
	
	Method Update()
		x=x+1
	End Method
End Type

'.....
Local MyObjList:Tlist = CreateList()

Local mytestobj:my = CreateMyObj()

For Local myobj:my = EachIn MyObjList
	If ( EventSource()=MyObj.Test )
		MyObj.Update()
	End If
Next

Function CreateMyObj:My()
	Local myobj:my = New my
	MyObjList.addlast myobj
	Return myobj
End Function

somthing like that should work

RJJ: if you add a field / global x that can be raised then yes, thats correct working source.

Diablo: Thanks the list is a good solution.

Dreamora: The issue isn't really the syntax. What I want to know is whether given the field test you can derive its object so that you can call the method update for that that instance.

Thanks
