How to get the selected item of a listview using pure API?

[halo]

If all you have is the windows handle of a listview, how do you get the listview state using Win32 API? No PB commands allowed. Thanks.

This will get the selected index number as well as the selected text, using API only.

Code: Select all

If OpenWindow(0, 0, 0, 300, 140,#PB_Window_SystemMenu | #PB_Window_ScreenCentered, "ListViewGadget") And CreateGadgetList(WindowID(0)) 
  CreateStatusBar(0, WindowID())
  hLVG = ListViewGadget(0, 10, 10, 280, 100) 
  For i = 0 To 9 
    AddGadgetItem (0, -1, "Test Item " + Str(i))
  Next 
  Repeat
    event = WaitWindowEvent()
    Select event
      Case #PB_EventGadget
        Select EventGadgetID()
          Case 0
            ; --> Get index of current ListView selection
            lbSel = SendMessage_(hLVG, #LB_GETCURSEL, 0, 0)
            ; --> Get text length of current selection
            lbTextLen = SendMessage_(hLVG, #LB_GETTEXTLEN, lbSel, 0)
            ; --> Buffer for selected text
            lbText$ = Space(lbTextLen1)
            ; --> Get selected text
            SendMessage_(hLVG, #LB_GETTEXT, lbSel, @lbText$)
            ; --> Display results
            StatusBarText(0, 0, "Selected item index (" + Str(lbSel) + ")  Selected item text (" + lbText$ + ")") 
        EndSelect
    EndSelect
  Until event = #PB_Event_CloseWindow 
EndIf 
End
