Re: [gtkmm] Glade-2, libgtkmm, Xml::create, callbacks

[Douglas Roberts <dzzr lanl gov>]

Hi, Christof.

Yes, glademm is being used, and I can save the gui to C++ code.  All the 
automake stuff is configured correctly, and the application compiles and 
runs.  The one piece that I can't find is the functional equivalent to 
lookup_widget() that glade provides for you in a file named 
"interface.h" when you save the GUI as C code.  Since I am now saving 
the GUI as C++ code, instead of looking up a gtk widget, I need to 
lookup the Gtk::object for each gui component.  The C++ objects are 
created in a file named

"glade_top_level_window_name"_glade.cc

Here's an example of where the objects are created for my "window1" 
object from the file named "window1_glade.cc" in the "src" directory of 
the code created by glade/glademm:

window1_glade::window1_glade(
) : Gtk::Window(Gtk::WINDOW_TOPLEVEL)
{ 
 
  Gtk::Window *window1 = this;
  gmm_data = new GlademmData(get_accel_group());
 
  Gtk::Label *lable1 = Gtk::manage(new class Gtk::Label(_("TA System")));
  Gtk::Label *current_date_label = Gtk::manage(new class 
Gtk::Label(_("Current Date")));
  Gtk::Entry *current_date_entry = Gtk::manage(new class Gtk::Entry());
  Gtk::VBox *vbox5 = Gtk::manage(new class Gtk::VBox(false, 0));
  Gtk::Label *analysis_start_date_label = Gtk::manage(new class 
Gtk::Label(_("Analysis Start Date")));
.
.
.

Aside from making these Gtk::Object type definations global, how do I 
get handles to them?
