The code block set in oBrowse: ItemMarked only works when there is a
vertical movement.
Thus, ItemMarked is not working with a single row browse and is not
working on the same row without vertical navigation.  
Is it possible to have ItemMarked executed without any navigation?

Many thanks,

I do not know if I understood correctly

***************************
CLASS BroTest FROM XbpBrowse
***************************
   INLINE METHOD navigate( nNavigate, mp2 )
   ****************************************
      LOCAL _rowPos:= ::rowPos
      LOCAL _colPos:= ::colPos

      super:navigate( nNavigate, mp2 )

      IF ::itemMarked # nil .AND. _rowPos = ::rowPos .AND. _colPos # 
::colPos
         PostAppEvent( xbeBRW_ItemMarked, { ::rowPos, ::colPos }, nil, 
self )
      ENDIF
   RETURN self
ENDCLASS

Thank you, Diego!
Yes, we can post ItemMarked programmatically, but not with the mouse.
For clarity, if the focus is already on a row, clicking that row does
nothing.  ItemMarked is generated only when the focus moves from one
row to another.  It would be nice to have ItemLbDown (similar to
ItemRbDown) so we can click a row that already has focus.

You mean this?

No.  I mean ::itemLbDown := bBlock
For example:
oBrowse:itemLbDown := {| aMousePos, aRowCol, self | DoSomething() }

ItemMark only activated when row id changed, while ItemLbDown should
be activated when the left-button is clicked.  They are not the same.

Thank you, Diego.
I've found a work around this via the CellGroup:lbDown:

//Set the call-back:
oBrowse:GetColumn(7):dataArea:lbDown := {|aPos, uNIL, self |
DoSomething(@oBrowse, @aBrowse, Self) } 


Static Procedure DoSomething(@oBrowse, @aBrowse, oCellGroup)
 move the cursor to the clicked line
PostAppEvent( xbeBRW_ItemMarked, { oCellGroup:cellFromPos(aPosition),
7 }, nil, @oBrowse )
 must stabilize the browser
oBrowse:forceStable()
 Retrieve the data selected
aLine := aBrowse[oBrowse:Cargo]
