Hey this is nice! A Faster way to populate and retrieve information!!! Nice Nice Nice.
thanks

Edit:
I was playing with the new 'things' like SyncDataSource() & KeysFromList$ and I'm attempting to run this code

Strict 

Local window:TGadget
Local listbox:TGadget

window=CreateWindow("My Window",30,20,200,400)
listbox=CreateListBox(0,0,ClientWidth(window),ClientHeight(window),window)
SetGadgetLayout listbox,1,1,1,1

Type oggetto
		Field valore:String
End Type

Global my_list:tlist = New tlist

For Local i = 1 To 100
Local	og:oggetto = New oggetto
	og.valore = String(i)
	my_list.addlast og
Next

listbox.SetDataSource my_list


While WaitEvent()
	Print CurrentEvent.ToString()
	Select EventID()
			
		Case EVENT_GADGETSELECT
			Local i=EventData()		'what got selected?
			If i=-1 Exit			'test for deselection			
			Local src$[]			'a string array to test eventextra
			src=String [] EventExtra()	'cast datasource to string array
			Notify "Select:"+src[i]	'combine datasource and index

		Case EVENT_WINDOWCLOSE
			End

	End Select
Wend

The gadgetlist report something different - address?
I read the source but I can't imagine how you can to add from my_list the field 'valore' to the gadgetlist...
