Re: [gtkmm] More on Struggling with signal_key_press_event with code

[Ian Michell <ian michell hanzi co uk>]

I have the code I am using here

LoginForm::LoginForm()
{
	// Set Alignent
	l_align = Gtk::manage(new Gtk::Alignment(Gtk::ALIGN_CENTER,
				Gtk::ALIGN_CENTER, 0.0, 0.0));
	// Create Table Layout
	l_table = Gtk::manage(new Table(2,2));
	l_align->add(*l_table);

	// Create Login Button
	l_button = Gtk::manage(new Gtk::Button("Login"));

	// Create Login Labels
	Label *lusername = Gtk::manage(new Gtk::Label("Username:"));
	Label *lpassword = Gtk::manage(new Gtk::Label("Password:"));

	// Create Entry Fields
	l_i_username = Gtk::manage(new Gtk::Entry);
	l_i_password = Gtk::manage(new Gtk::Entry);

	// Configure Entry Fields
	l_i_username->set_max_length(20);
	l_i_password->set_max_length(20);
	l_i_password->set_visibility(false);
	l_i_password->set_invisible_char('*');

	// Add Item to table
	l_table->attach(*lusername, 0, 1, 0, 1, Gtk::FILL | 
			Gtk::SHRINK, Gtk::FILL | Gtk::SHRINK, 5, 5);
	l_table->attach(*l_i_username, 1, 2, 0, 1, Gtk::FILL | 
			Gtk::SHRINK, Gtk::FILL | Gtk::SHRINK, 5, 5);
	l_table->attach(*lpassword, 0, 1, 1, 2, Gtk::FILL | 
			Gtk::SHRINK, Gtk::FILL | Gtk::SHRINK, 5, 5);
	l_table->attach(*l_i_password, 1, 2, 1, 2, Gtk::FILL | 
			Gtk::SHRINK, Gtk::FILL | Gtk::SHRINK, 5, 5);

	// Add Aligned Table to frame
	add(*l_align);

	// Connect Signals
	l_i_username->signal_key_press_event().connect(
			SigC::slot(*this, &LoginForm::login_action));

}

LoginForm::~LoginForm()
{
}

bool LoginForm::login_action(GdkEventKey* k)
{
	// Remove Login Frame
	if (k && k->keyval == GDK_Return)
		std::cout << "Hello World\n";
	return false;
}

Please tell me where I am going wrong
