Re: About Gtk::Bin?

Actually, I have no idea why it does not work. Seems to be a problem
with the Gtk::Bin. I replaced it with a Box and it worked.

#include <gtkmm.h>

class Viewer : public Gtk::HBox
{
  private:
    Gtk::Table table_;
    Gtk::Button button_;

  public:
    Viewer() : table_(2, 2), button_("ZHU")
    {
      table_.attach(button_, 0, 1, 0, 1);
      pack_start(table_);
    }
};

class Window : public Gtk::Window
{
  private:
    Viewer viewer_;

  public:
    Window()
    {
      add(viewer_);
      show_all();
    }
};

int main (int argc,char *argv[])
{
    Gtk::Main kit(argc, argv);
    Window win;
    kit.run(win);
    return 0;
}
