Hi Dan,
I've got something working.

The problem seems to be that Windows grabs focus again when you release the
mouse button. The method below is not foolproof but it works kinda...

Just replace the event handler code and setHandler() thus...


object w w = -2
procedure TreeView2_onChange (integer self, integer event, sequence
params)--params is ()
    object x

    if event = w32HClick then
        w = -1 -- Begin processing mouse movements.
    else
        if params[1] = WM_MOUSEMOVE and equal(w,-1) then
            x = getTVIndex(TreeView2)
            if equal(w,x) = False then
                setText(MleText3, "Item " & sprint(getTVIndex(TreeView2)) &
                     CrLf & "I would like that the user could start " &
                      "entering text at the end of this text immediately
after selecting a TV item," &
                      " without having to click the mouse over here first. "
&
                      " Focus was just set here, but doesn't seem to work.")
                setFocus(MleText3)
                setIndex(MleText3, {1,0}) -- hilite all the text.
                w = x
            end if
        end if
    end if
end procedure
setHandler( TreeView2, {w32HEvent, w32HClick},
routine_id("TreeView2_onChange"))

cheers,
