Hi Robert,
yes, I changed the code a bit, but with no affect. There seems to be a
bug with Gtk::Bin or a reason I don't know. Here is a simplest-possible
testcase that confirms that it does not work (at least for me and Zhu):
#include <gtkmm.h>
class MyBin : public Gtk::Bin
{
public:
MyBin (void)
{ add(*Gtk::manage(new Gtk::Button("My Button"))); }
};
int
main (int argc, char** argv)
{
Gtk::Main kit(argc, argv);
Gtk::Window win;
win.add(*Gtk::manage(new MyBin));
win.show_all();
kit.run(win);
return 0;
}
