Catching a mouse click inside a Gtk::Entry

[Christian Schaubschlaeger <cs gup uni-linz ac at>]

Hello list,

I want to catch a mouse click event inside a Gtk::Entry. I tried
it with connecting to the entry's on_button_release_event() (see
code below). Unfortunately this does not work as expected: it seems
that on_button_release_event() is not emitted when I click _inside_
the entry, but only when I click on the entry's border... How can
I catch a click inside the entry?

I tried this with gtkmm-2.18.2

Thanks,
Christian


#include <iostream>
#include <gtkmm.h>

bool
on_entry_clicked(GdkEventButton *b)
{
  std::cout << "Clicked\n";
  return true;
}

int main(int argc, char **argv)
{
  Gtk::Window *w;
  Gtk::VBox *v;
  Gtk::Button *b;
  Gtk::Entry *e;

  Gtk::Main gtk_main(argc,argv);

  // new window + vbox
  w = new Gtk::Window();
  //w->add_events(Gdk::BUTTON_PRESS_MASK | Gdk::BUTTON_RELEASE_MASK);
  w->show();

  v = new Gtk::VBox();
  w->add(*v);
  v->show();

  // quit button
  b = new Gtk::Button();
  v->pack_start(*b,Gtk::FILL,Gtk::FILL);
  b->set_label("Quit");
  b->show();
  b->signal_clicked().connect(sigc::ptr_fun(Gtk::Main::quit));

  // entry
  e = new Gtk::Entry();
  v->pack_start(*e,Gtk::FILL,Gtk::FILL);
  e->show();
  //e->add_events(Gdk::BUTTON_PRESS_MASK | Gdk::BUTTON_RELEASE_MASK);
  e->signal_button_release_event().connect(sigc::ptr_fun(on_entry_clicked));

  gtk_main.run();

  return 0;
}
