Taskbar Buttons

[Glus Xof <gtglus gmail com>]

Hi guys,

Here goes a simple code:

---
#include <gtkmm.h>

class sWindow
: public Gtk::Window
{
public:
   sWindow();
   virtual ~sWindow(){}
};

sWindow::sWindow()
{
   set_title ("2nd Window");
}


class mWindow
: public Gtk::Window
{
public:
   mWindow();
   virtual ~mWindow(){}

   void show_swindow();

private:
   sWindow swindow;;
};

void mWindow::show_swindow()
{
   set_title ("1st Window");
   swindow.show_all();
}

mWindow::mWindow()
{
   show_all();
   show_swindow();
}

int main (int argc, char *argv[])
{
   Glib::RefPtr<Gtk::Application> mApp =
      Gtk::Application::create (argc, argv, "org.gtk");

   mWindow window;

   return mApp->run (window);
}
---

This simply throws two Gtk::Window objects... with their own buttons
on my desktop taskbar, one for each window.

If need to minimize the "1st Window", I only click one of its own
buttons (the "_" in the window decoration or the taskbar one) , while
the "2nd Window" rests visible in screen... but,

(My question is:) There is a way to joint these two windows in the
same button to minimize / maximize them together ?
