Hi, these are the crazy tips to get tooltips working

//In the mainwin.cpp add:
//start example code
====================================================
mpActionGroup = Gtk::ActionGroup::create();
	mpActionGroup->add(Gtk::Action::create("fileMenu", "_File"));

	mpActionGroup->add(Gtk::Action::create("fileOpen", 
	                       "Open ISO file", "Open ISO file to examine
content"),
	                       sigc::mem_fun(*this,
&mainwin::on_selectIsoFileButton_click));

	mpActionGroup->add(Gtk::Action::create("fileQuit", "_Exit", "Exit /
terminate the application"),
	                   	sigc::mem_fun(*this,
&mainwin::on_exitButton_click));

	mpActionGroup->add(Gtk::Action::create("helpMenu", "_Help"));

	mpActionGroup->add(Gtk::Action::create("helpHowTo", "_How to", "Search
for help"),
	                   sigc::mem_fun(*this, &mainwin::on_howTo_click));

	mpActionGroup->add(Gtk::Action::create("helpAbout", "_About", "This
shows the about dialog: Ver. 1.0.0"),
	                   sigc::mem_fun(*this, &mainwin::on_about_click));
	
	mpUiManager = Gtk::UIManager::create();
	mpUiManager->insert_action_group(mpActionGroup);

mpUiManager->add_ui_from_file("ui.xml");
mpUiManager->signal_connect_proxy().connect(sigc::mem_fun(this,
&mainwin::install_menu_hints));

	//add accelerators to the main window:
		add_accel_group(mpUiManager->get_accel_group()) ;

		mpptrmenuBar = mpUiManager->get_widget("/menuBar");
		
		HBoxMenuBar.pack_start(*mpptrmenuBar, true, true, 15);

//3- The related functions are as follows:

void mainwin::install_menu_hints(const Glib::RefPtr<Gtk::Action>&
action, Gtk::Widget* widget)
{
    if(dynamic_cast<Gtk::MenuItem*>(widget))
    {

(static_cast<Gtk::MenuItem*>(widget))->signal_select().connect(sigc::bind(sigc::mem_fun(*this, &mainwin::on_show_menu_tip), action));

(static_cast<Gtk::MenuItem*>(widget))->signal_deselect().connect(sigc::mem_fun(*this, &mainwin::on_clear_menu_tip));
    }
}

void mainwin::on_show_menu_tip(const Glib::RefPtr<Gtk::Action>& action)
{
    Glib::ustring tip = action->property_tooltip();
    if (tip == "") tip = " ";
    m_statusBar.push(" " + tip);
}

void mainwin::on_clear_menu_tip()
{
    m_statusBar.pop();
}
 
// end of example code to add in the mainwin.cpp
==============================

//The ui.xml file is as follows:

<ui> 
	<menubar name='menuBar'>
		<menu action='fileMenu'>
			<menuitem action='fileOpen'/>
			<separator/>
			<menuitem action='fileQuit'/>
		</menu>
		<menu action='helpMenu'>
			<menuitem action='helpHowTo'/>
			<menuitem action='helpAbout'/>
		</menu>
	</menubar>
</ui>

//++++++++++And my mainwin.h is as follows: ++++++++++++++
#include <gtkmm.h>
#include <gtkmm/menu.h>
#include <gtkmm/menubar.h>
#include <gtkmm/menuitem.h>

class mainwin : public Gtk::Window
