Re: making menuitems insensitive by app context

Hello, 

I can give you a sollution in this subject, using
UIManager and Gtk::ActionGroup for the menu and the
menuitems.
Still, i'm not using libgladem, but only gtkmm 2.4 and
glibmm 2.4. 
Here is the code :


/*MenuBar*/
		
	// create the action group
	actionGroup = Gtk::ActionGroup::create();
	
	// File Menu

actionGroup->add(Gtk::Action::create("Fichier","_Fichier"));
	
	string tipCre = "Créer un nouveau fichier";
	Glib::ustring tipp = Glib::locale_to_utf8(tipCre);
	
	// File|New

actionGroup->add(Gtk::Action::create("Nouveau",Gtk::Stock::NEW,"_Nouveau",tipp),
		sigc::mem_fun(*this,&MainPage::on_New_File));
		
	//File|Open	

actionGroup->add(Gtk::Action::create("Ouvrir",Gtk::Stock::OPEN,"_Ouvrir","Ouvrir
un fichier"),
		sigc::mem_fun(*this,&MainPage::on_Open_File));
		
	//File|Save

actionGroup->add(Gtk::Action::create("Sauvegarder",Gtk::Stock::SAVE,Glib::locale_to_utf8("Enregistrer"),"Enrégistrer
sur le disque"),
		sigc::mem_fun(*this,&MainPage::on_Save_File));	
		
	//File|Save As
	actionGroup->add(Gtk::Action::create("Save
As",Gtk::Stock::SAVE_AS,Glib::locale_to_utf8("_Enregistrer
sous..."),"Enrégistrer sur le disque"),
		sigc::mem_fun(*this,&MainPage::on_Save_As_File));	
	
	//File|Close

actionGroup->add(Gtk::Action::create("Quitter",Gtk::Stock::QUIT,"_Quitter","Quitter"),
		sigc::mem_fun(*this,&MainPage::on_Close_File));
			
	//Editer

actionGroup->add(Gtk::Action::create("Editer","_Editer"));

	
	//Editer|Undo
	actionGroup->add(Gtk::Action::create("Select
All",Glib::locale_to_utf8("Tout
selectionner"),"Quitter"),
	
Gtk::AccelKey("<control>A"),sigc::mem_fun(*this,&MainPage::on_select_all));
		
	//Editer|Redo

actionGroup->add(Gtk::Action::create("Find",Gtk::Stock::FIND,"Rechercher","Quitter"),
		sigc::mem_fun(*this,&MainPage::on_find));
	
	//Editer|Cut

actionGroup->add(Gtk::Action::create("Cut",Gtk::Stock::CUT,"Couper","Quitter"),
		sigc::mem_fun(*this,&MainPage::on_clicked_Cut));
		
	//Editer|Copy

actionGroup->add(Gtk::Action::create("Copy",Gtk::Stock::COPY,"Copier","Quitter"),
		sigc::mem_fun(*this,&MainPage::on_clicked_Copy));
		
	//Editer|Paste

actionGroup->add(Gtk::Action::create("Paste",Gtk::Stock::PASTE,"Coller","Quitter"),
		sigc::mem_fun(*this,&MainPage::on_clicked_Paste));		
	
	
	//Outils 

actionGroup->add(Gtk::Action::create("Outils","_Outils"));
	
	//Outils|Boot LVC

actionGroup->add(Gtk::Action::create("Boot_LVC",Gtk::Stock::EXECUTE,"_Boot
BTL","Ouvrir fichier BTL"),
		sigc::mem_fun(*this,&MainPage::on_BootLVC));	
		
	//Outils|Reset OBC

actionGroup->add(Gtk::Action::create("Reset_OBC",Gtk::Stock::EXECUTE,"_Reset
OBC","Reset OBC"),
		sigc::mem_fun(*this,&MainPage::on_ResetOBC));	
	
	//Outils|Init CTX TM

actionGroup->add(Gtk::Action::create("Init_CTX_TM",Gtk::Stock::EXECUTE,"_Init
CTX TM","Init CTX TM"),
		sigc::mem_fun(*this,&MainPage::on_Init_CTX_TM));	
		
	//Outils|CFG FEPROM

actionGroup->add(Gtk::Action::create("CFG_FEPROM",Gtk::Stock::EXECUTE,"GC
FE_PROM","GC FEPROM"),
		sigc::mem_fun(*this,&MainPage::on_CFG_FEPROM));		
		
	//Outils|CFG FRAM

actionGroup->add(Gtk::Action::create("CFG_FRAM",Gtk::Stock::EXECUTE,"GC
F_RAM","GC FRAM"),
		sigc::mem_fun(*this,&MainPage::on_CFG_FRAM));			
	
	//gestion de configuration Menu
	actionGroup->add(Gtk::Action::create("Gestion de
configuration","_Gestion de configuration"));
	
	//gestion de configuration Menu| chekin 

actionGroup->add(Gtk::Action::create("Check-In",Gtk::Stock::REDO,"Check
IN","Check in"),
		sigc::mem_fun(*this,&MainPage::check_in));	
	
	//gestion de configuration Menu| chekout

actionGroup->add(Gtk::Action::create("Check-Out",Gtk::Stock::UNDO,"Check
OUT","Check out"),
		sigc::mem_fun(*this,&MainPage::check_out));	
	
	//About
	actionGroup->add(Gtk::Action::create("?","_?"));
	
	//About|About
	actionGroup->add(Gtk::Action::create("A
Propos",Gtk::Stock::DIALOG_INFO,"_A Propos","About"),
		sigc::mem_fun(*this,&MainPage::on_About));
	
	// now create the uiManager	
	uiManager = Gtk::UIManager::create();

	uiManager->insert_action_group(actionGroup);

	// the toolbar is created from the menubar items 
	
	try{
		static const Glib::ustring uiMake = 
			"<ui>"
			"  <menubar name='MenuBar'>"
			"    <menu action='Fichier'>"
			"      <menuitem action='Nouveau'/>"
			"      <menuitem action='Ouvrir'/>"
			"      <menuitem action='Sauvegarder'/>"
			"      <menuitem action='Save As'/>"
			"      <separator/>"
			"      <menuitem action='Quitter'/>"
			"    </menu>"
			"    <menu action='Editer'>"
			"      <menuitem action='Select All'/>"
			"      <menuitem action='Find'/>"
			"      <separator/>"
			"      <menuitem action='Cut'/>"
			"      <menuitem action='Copy'/>"
			"      <menuitem action='Paste'/>"
			"    </menu>"
			"    <menu action='Outils'>"
			"      <menuitem action='Boot_LVC'/>"
			"      <menuitem action='Reset_OBC'/>"
			"      <menuitem action='Init_CTX_TM'/>"
			"      <menuitem action='CFG_FEPROM'/>"
			"      <menuitem action='CFG_FRAM'/>"
			"    </menu>"
			"    <menu action='Gestion de configuration'>"
			"      <menuitem action='Check-In'/>"
			"      <menuitem action='Check-Out'/>"
			"    </menu>"
			"    <menu action='?'>"
			"      <menuitem action='A Propos'/>"
			"    </menu>"
			"  </menubar>"
			"</ui>";
		
		// add menubar from string
		uiManager->add_ui_from_string(uiMake);
}catch(const Glib::Error &ex){
		cout<<"Impossible de construire le menubar"<<endl;
	}
	
	menuWidget = uiManager->get_widget("/MenuBar");

et enable/disable stuff here :
//////////////////////////////////////////////////////
Gtk::Widget *nouveau =
uiManager->get_widget("/MenuBar/Fichier/Nouveau");
disable_Widget(nouveau);
Gtk::Widget *quitter =
uiManager->get_widget("/MenuBar/Fichier/Quitter");
enable_Widget(quitter);

////////////////////////////////////////////////////////

void enable_Widget(Gtk::Widget *widget){
	
	widget->set_sensitive(true);
}

void disable_Widget(Gtk::Widget *widget){
	widget->set_sensitive(false);
}


I hope this helps.
