ListViewItem not responding to SetOnEvent

[andybiochem]

If the number of delimited items in the "text" of a ListViewItem is greater than the number of columns in the ListView control itself, the ListViewItem will not respond to a SetOnEvent declaration.

Reproducer:

Opt("GUIOnEventMode", 1)

GUICreate("", 220, 150)

;----- NOT WORKING -----
$ListView1 = GUICtrlCreateListView("Col1|Col2|Col3", 10, 10, 190, 50)
GUICtrlCreateListViewItem("first|second|third|fourth",$ListView1)
GUICtrlSetOnEvent(-1,"_Selected")

;----- WORKING OK -----
$ListView2 = GUICtrlCreateListView("Col1|Col2|Col3|Col4", 10, 70, 190, 50)
GUICtrlCreateListViewItem("first|second|third|fourth",$ListView2)
GUICtrlSetOnEvent(-1,"_Selected")

GUISetState(@SW_SHOW)

While 1
    Sleep(100)
WEnd

Func _Selected()
    ConsoleWrite(@GUI_CtrlId & @CRLF)
EndFunc

... clicking on the top ListViewItem does not call the function set by 'GUICtrlSetOnEvent'.

The second ListViewItem works as it should.

Just discovered ​here that the problem is due to GUICtrlCreateListViewItem not returning a control ID upon creation. If the control creation fails, so be it, but the ListViewItem IS actually created in this case, and appears in the ListView control.

Just read the doc the control can fail and you are in the case
