Hi,
I'm trying to connect to the configure signal
event(signal_configure_event()), in the documentation I read that
you have to enable Gdk::STRUCTURE_MASK, and I think that is the
problem I am having. I tried do it several different ways, like
this:
this->add_events(Gdk::STRUCTURE_MASK);
Gtk::Window::add_events(Gdk::STRUCTURE_MASK);
MainWindow::add_events(Gdk::STRUCTURE_MASK); //I think they are
all synonyms, but just in case they weren't
and I tried using set_events() function too. Is this the correct
way to enable STRUCTURE_MASK?
Thank you.

Have you read
https://developer.gnome.org/gtkmm-tutorial/stable/sec-xeventsignals.html.en#signal-handler-sequence
and added an after = false parameter in your call to
signal_configure_event().connect()?
Kjell
Thank you for the link, but I recently just read that using the
configure signal could have performance problems, and I read in an
old mailing list that signal_expose_event should be used, which is
now signal_draw. So instead I was thinking of using
signal_size_allocate. Because all I really want is just the
window's size. So which one of these would have better for getting
the window's size and then increases a Gtk::Entry width. Thank you.

Is this a continuation of your question in
https://mail.gnome.org/archives/gtkmm-list/2013-November/msg00070.html ?
I made a small test with the example program in
https://git.gnome.org/browse/gtkmm-documentation/tree/examples/book/entry/simple?h=master
I changed the vertical box to a horizontal box. The Entry widget
expands with the window if it's added to the box with
pack_start(m_Entry, Gtk::PACK_EXPAND_WIDGET). If you want the Entry
to get all extra space, you should add other widgets to the box with
Gtk::PACK_SHRINK.
If you can't get this to work, can you post a small program here on
the mailing list? A program that does not behave the way you want,
when its window is expanded.
Kjell
Here is how I solved it the problem, probably not the best way, but
it works kind of:
When I ran your program (deleted from this reply), I realized that I
had misunderstood your intention. You don't want the Entry to grow
when the user increases the size of the parent window. You want the
Entry to grow when the user enters text in it. You want it always to
be large enough to show all the entered text. I don't know an easy way
of achieving that. Perhaps you can simplify your program somewhat by
using Gtk::Editable::signal_changed() instead of
signal_key_press_event() and signal_delete_text(), and by using
Gtk::Entry::set_width_chars().
Kjell
I actually want to do both at the same time. I will try and use
Gtk::Editable::signal_change() and Gtk::Entry::set_sidth_chars(). Thank
you for those suggestions. Also, thank you Andrew Potter for the
Gtk::ALIGN_FILL suggestion, but when I tried that the entry text box was
not centered.
