Listbox macro

How I do I have a list box that can get the position of the selected item. So if I have an item selected it would print 1 or what ever. I am told you do this in basic like this:

items = Student.SelectedItems

Print items(0)

but it gives this instead

For example:

doc = ThisComponent
form = doc.DrawPage.Forms.getByName("MainForm")
list = form.getByName("lst_students")
Msgbox list.SelectedValue

But, if you call code from other control in the same form, you can access form with:

Sub cmd_selected_studen(event)	
	form = event.Source.Model.Parent
	list = form.getByName("lst_students")
	Msgbox list.SelectedValue
End Sub

Get selected position:

form = event.Source.Model.Parent
list = form.getByName("lst_students")
list_view = ThisComponent.CurrentController.getControl(list)
Msgbox list_view.SelectedItemPos

But I would like to know the position of the name in the list of 5 others. Is it #1, #2, #3, #4, or #5?

add example.
