Re: Glib::Thread && Gtk::Window

Alexander,

Are you accidentally calling set_geometry_hints (or some other method that invokes
set_geometry_hints internally) before the corresponding window has been realized?
I suggest that you use the cout-statement or GDB to locate the exact line that emits
these errors.  You then insert win.show_all() in front of it.  Making sense?


Best,

Nickolai

Hi everybody!
I need to have more than one window in program, working
at the same time. In Main window I have table with windows title,
address for manipulation with windows.
I use Glib::Thread to create threads for new window:

Main_Window::Main_Window()
{
        Glib::thread_init();
        ...
}

void Main_Window::on_Open_clicked()
{
        Glib::Thread *thread = Glib::Thread::create(sigc::mem_fun(*this, &Main_Window::new_thread), true);
        //thread->join();
}

void Main_Window::new_thread()
{
        cout << "Main_Window::new_thread()...\n";

        DB_ID_TYPE id = 2;

        input_wnd = new InputWindow(id);

        Gtk::TreeModel::Row row = *(refptr_Windows->append());
        row[tablemodel_Windows.column_address] = input_wnd;
        row[tablemodel_Windows.column_id] = refptr_Windows->children().size();
        row[tablemodel_Windows.column_title] = input_wnd->get_title();

        Gtk::Main::run(*input_wnd);
}

When I try to run Window:

(echo.exe:1240): Gdk-CRITICAL **: gdk_window_set_geometry_hints: assertion `wind
ow != NULL' failed
(echo.exe:1240): Gdk-CRITICAL **: gdk_window_resize: assertion `window != NULL'
failed
(echo.exe:1240): Gdk-CRITICAL **: gdk_window_set_geometry_hints: assertion `wind
ow != NULL' failed
(echo.exe:1240): Gdk-CRITICAL **: gdk_window_resize: assertion `window != NULL'
failed

and new window

And one more quastion:
maybe here is another way to do what I want?
