[glade--]How to access sibling widgets?

Hello,

when having a widget tree like

| window1
| `- vbox1
|    |- entry1
|    `- entry2

marking entry1/entry2 as public and generating a separate class and file
for them, how can I access entry1 from entry2?

glade-- creates the following code

| window1_glade::window1_glade(...)
| {
|   ...
|   _data = new GlademmData(get_accel_group());
|    
|   entry1 *entry1 = Gtk::manage(new class entry1(_data));
|   entry2 *entry2 = Gtk::manage(new class entry2(_data));
|   ...
| }

which does not give any information about 'entry1' to 'entry2'.

When modifying glade-- to generate other constructors which are taking
the parent-object as an argument, code like

 --- window1_glade.cc
|   entry1 *entry1 = Gtk::manage(new class entry1(*this));
|   entry2 *entry2 = Gtk::manage(new class entry2(*this));

 --- entry2.hh
| class window1_glade;
| class entry2 : public entry2_glade
| { ...
|    entry2(window1_glade &data) : entry2_glade(data)

could be created and 'entry1' would be accessible through 'data.entry1'. I do
not know why 'window1.get_accel_group()' was encapsulated in a GlademmData
object, but it would be still accessible through 'data.get_accel_group()'.

The documentation mentions GMM_* macros, but they do not seem to exist
anymore.

I am using glademm-1.1.3d with gtkmm2.
