How to translate text strings of GtkUIManager file.

[Osmo Maatta <osmoma gmail com>]

Hello,

I have a question about how to get text strings translated when I use 
GtkUIManager to build a GUI (menu and toolbar).

This example is from my Gscreendump (screenshot taking...) application.

I have a XML syntax for the GUI in:  
http://code.google.com/p/gscreendump/source/browse/trunk/src/sd_menu_ui.h

Then in the c code:

#include "sd_menu_ui.h"

static GtkActionEntry open_entries[] =
{
 { "FileNewMenuAction", GTK_STOCK_NEW,
   "_New Capture", ""}, <--- HOW TO GET THIS TRANSLATED?
  
 { "FileNewWindowAction", NULL,
   "_Window", "<control>1",
   "Take a screenshot of a selected window.", <--- HOW TO GET THIS 
TRANSLATED etc. ?
   G_CALLBACK(on_m_new_window_activate_cb)},

 { "FileNewSelectionAction", NULL,
   "_Selection", "<control>2",
   "Take a screenshot of a selected area of the desktop.",
   G_CALLBACK(on_m_new_select_activate_cb)},

 { "FileNewDesktopAction", NULL,
   "_Desktop", "<control>3",
   "Take a screenshot of the entire desktop.",
   G_CALLBACK(on_m_new_desktop_activate_cb)},

  ...
};


/* Then load the UI for menu and toolbar */
GError *error = NULL;
gtk_ui_manager_add_ui_from_string(g_ui_manager, ui_xml, -1, &error);
...

---------------------------

All strings of the the c-code are automatically collected because 
strings are confined by translation macro  _("some text"). But I cannot 
use _("xxxx") in the GtkActionEntry entries (e.g  open_entries[] list).

So do you know how to automatically collect and output strings from all 
the GtkActionEntry lists to ./po/gscreendump.pot file.
The .pot is the message/text file that already contains all strings from 
_("xxxxx"). It is then translated to other languages.

But my problem is the text strings in all GtkActionEntry structures.
---------------------------

I have added gtk_action_group_set_translation_domain() lines to my code, 
but I cannot see how it works.

GtkActionGroup *open_action_group = 
gtk_action_group_new("AlwaysOpenActions");
gtk_action_group_add_actions(open_action_group, open_entries, 
n_open_entries, NULL);
gtk_ui_manager_insert_action_group(g_ui_manager, open_action_group, 0);
gtk_action_group_set_translation_domain(open_action_group, GETTEXT_PACKAGE);
-----------------------------

Sorry for possibly bad explanation, but this is my reality now.

The entire Gscreendump code is available from: 
http://code.google.com/p/gscreendump (study the amazing pictures ;-)
And the latest source code:
