Hi!
I want to create a base class for my window and dialog classes, the
structure looks lik this:
class Base : public Glib::Object
{
public:
Base()
: Glib::ObjectBase(typeid(Base))
, p(*this, "p")
{
}
Glib::Property<Glib::ustring> p;
};
class WindowBase : public Base, public Gtk::Window
{
public:
WindowBase()
: Glib::ObjectBase(typeid(WindowBase))
, Base()
, Gtk::Window
{
}
};
class DialogBase : public Base, public Gtk::Dialog
{
public:
DialogBase()
: Glib::ObjectBase(typeid(DialogBase))
, Base()
, Gtk::Dialog
{
}
};
class MyWindow : public WindowBase
{
public:
MyWindow()
: WindowBase()
{
}
};
When i want to instantiate the MyWindow, I get the following error:
glibmm:ERROR:objectbase.cc:78:void
Glib::ObjectBase::initialize(GObject*): assertion failed: (gobject_ ==
castitem)
I think it's because the multiple inheritance of Glib::Object from Base
and from Gtk::Window, but I can not find a solution.
Any help is appreciated:
