   Clicking on a listview fires the listview click event, it also sets 
the selected property to True. Normally the programmer would not have a 
need to programatically set the selected property to True, which is not 
to say it can't be done,.. but begs the question "should it be done".
   If the user clicks on an item in a listview it sets that item to a 
selected state and it will also set that item as the current item. The 
following code can be pasted into a blank form.. add a button, a 
listview, and a text area, keep the names of these controls to their 
defaults.

' Gambas class file

Public Sub Button1_Click()
   PopulateList
End


Public Sub ListView1_Click()
   TextArea1.Text = ListView1.Item.Selected & " " & ListView1.Item.Text 
& " " & ListView1.Current.Key
End


Private Sub PopulateList()
     With ListView1
        .Add("A", "A")
        .Add("B", "B")
        .Add("C", "C")
        .Add("D", "D")
    End With

End

   Click the button and the list populates. Click on any item in the 
list and the text area will display the Selected State, the Text, and 
the Key (which in this case will be the same as the text).
