Using set_focus_chain()

[Romain Behar <romainbehar yahoo com>]

I have a big table with buttons, entries and labels,
and would make the TAB key jump to next entry instead
of going through every widget. The set_focus_chain()
seems to exist for this purpose, but I couldn't make
it work.

Below is the full source code for a simple window with
a 2x2 table containing :

 Entry1   Button1
 Entry2   Button2

The set_focus_chain() runs with a list containing {
Entry1, Entry2 } but doesn't modify TAB key behaviour.

 Any hint?

 Regards,

#include <gtkmm.h>
#include <iostream>

class ExampleWindow : public Gtk::Window
{
public:
  ExampleWindow::ExampleWindow() :
    m_Table(2, 2, false)
  {
    set_size_request(300, 100);
    set_title("Gtk::Entry");

    add(m_Table);

    m_Entry1.set_text("1");
    m_Table.attach(m_Entry1, 0, 1, 0, 1);
    m_Entry2.set_text("2");
    m_Table.attach(m_Entry2, 0, 1, 1, 2);

    m_Table.attach(m_Button1, 1, 2, 0, 1);
    m_Table.attach(m_Button2, 1, 2, 1, 2);

	// Tab
	GList* entry_list = 0;
	entry_list = g_list_append(entry_list,
m_Entry1.gobj());
	entry_list = g_list_append(entry_list,
m_Entry2.gobj());
	std::cerr << "size : " << g_list_length(entry_list)
<< std::endl;

set_focus_chain(Glib::ListHandle<Gtk::Widget*>(entry_list,
Glib::OWNERSHIP_NONE));
	g_list_free(entry_list);

    show_all_children();
  }
