Create My wxListCtrl, wxLC_REPORT:

ListCtrl[q] = New TMyListCtrl.Create_MyListCtrl(po, b, _x, _y, _w, _h, wxLC_REPORT)

Step thru all the wxListCtrl Items:

Local n:Int = 1
Repeat
	Local _li:wxListItem = New wxListItem.Create()
	_li.setID(n)
	ListCtrl[q].getItem(_li)
	echo "id: " + _li.getID() + " :: [" + _li.getText() + "] == [" + ListCtrl[q].GetItemText(n) + "]"		' both are the same they get text at Column 0
	
	echo "---->[" + ListCtrl[q].OnGetItemText(n, 1) + "] :: id/n: " + _li.getID()					' I can't get ListCtrl[q].OnGetItemText to work (this need wxLC_VIRTUAL)!
	n = ListCtrl[q].GetNextItem(n)
Until n = -1

I can't use wxLC_VIRTUAL when I use:

_column = ListCtrl[q].insertItem(wxListItem)

How can I catch the text for column > 0?

Hi MOBii,

here is a method that I use to get item from listctrl

	Method GetListviewItem:String(index:Int, col:Int)
		If GetWindowStyle() & wxLC_REPORT Then
			Local info:wxListItem = New wxListItem.Create()
			info.SetId(index)
			info.SetColumn(col)
			info.SetMask(wxLIST_MASK_TEXT)
			If GetItem(info) Then
				Return info.GetText()
			Else
				Return ""
			End If
		End If
	EndMethod

Thank thee Henri

info.SetColumn(col)
info.SetMask(wxLIST_MASK_TEXT)
GetItem(info)

info.SetMask(wxLIST_MASK_TEXT)
The point of SetMask is to speed up the reading (only get the text data)?

It's there just to make sure that text data is retrieved, which it might not be by default. There maybe some speed gains for just getting that particular info, but they are almost negligible in real world.
