I use gcc and toolUndo->add_events (Gdk::POINTER_MOTION_MASK | 
Gdk::ENTER_NOTIFY_MASK ); doesn't change anything either.
Let me show some sourcecode:

class MainWindow:public Gtk::Window {
...
  protected:
     Gtk::ToolButton *toolUndo;
     virtual bool nothingExec(GdkEventCrossing* event);
     virtual bool nothingClick(GdkEventButton* event);
...
};

MainWindow::MainWindow(){
...
  toolUndo=Gtk::manage(new Gtk::ToolButton(iconToolUndo));
  toolUndo->add_events (Gdk::POINTER_MOTION_MASK | 
Gdk::ENTER_NOTIFY_MASK );
  
toolUndo->signal_enter_notify_event().connect(sigc::mem_fun(*this,&MainWindow::nothingExec));
  
toolUndo->signal_button_press_event().connect(sigc::mem_fun(*this,&MainWindow::nothingClick));
  toolUndo->signal_clicked().connect(sigc::mem_fun(*this, 
&MainWindow::nothingToDo));
...
}

void MainWindow::nothingToDo(){
  std::cout << "nothing to do" << std::endl;
}

bool MainWindow::nothingExec(GdkEventCrossing* event){
  std::cout << "nothing to exec" << std::endl;
  return false;
}

bool MainWindow::nothingClick(GdkEventButton* event){
  std::cout << "nothing to click" << std::endl;
  return false;
}
