Hi!
I have a quite simple program trying to create a dialog with help of
gtkmm and libglademm. In the response handler I want to delete the
'Dlg' object, since it is no longer needed.
I have reported this also in bugzilla (bug#87912), but it seems
bugzilla doesn't like me and doesn't accept my attachments, so i'm
posting here.
I have attached the program, the used glade file and a gdb backtrace.
/* Compile with:
* g++ -g -o test test.cc `pkg-config --cflags --libs libglademm-2.0 gtkmm-2.0`

#include <libglademm.h>
#include <gtkmm/main.h>

{

Dlg() {
Glib::RefPtr<Gnome::Glade::Xml> glade_xml =
Gnome::Glade::Xml::create("test.glade", "test_dialog");
glade_xml->get_widget("test_dialog", dlg_);
dlg_->signal_response().connect(slot(*this, &Dlg::response));
Gtk::Button *btn;
glade_xml->get_widget("button", btn);
btn->signal_clicked().connect(slot(*this, &Dlg::button_clicked));
}
void show() {
dlg_->show_all();
}
void response(int id) {
delete this;
}
void button_clicked() {
cout << "button_clicked" << endl;
}
private:
Gtk::Dialog *dlg_;
};
int main(int argc, char *argv[])
{
Gtk::Main gtk_main(argc, argv);
Dlg *dlg = new Dlg;
dlg->show();
gtk_main.run();
}
