This works for me (tested on linux)

    Frame = wxFrame:new(Wx, ?wxID_ANY, "Frame"),
    TB = wxFrame:createToolBar(Frame),
    wxToolBar:addTool(TB, 747, "PressMe",
wxArtProvider:getBitmap("wxART_COPY", [{size, {16,16}}]),
		      [{shortHelp, "Press Me"}]),

    Add = fun(#wx{}, _) ->
		  wxToolBar:addTool(TB, -1, "Added",
wxArtProvider:getBitmap("wxART_TICK_MARK", [{size, {16,16}}]),
				    [{shortHelp, "Test 2 popup text"}])
	  end,

    wxFrame:connect(Frame, command_menu_selected, [{callback, Add}, {id, 747}]),
    wxFrame:show(Frame),
