I need to add the following functions:
virtual Gtk::SizeRequestMode get_request_mode_vfunc() const;
virtual void get_preferred_width_vfunc(int& minimum_width, int&
natural_width) const;
virtual void get_preferred_height_for_width_vfunc(int width, int&
minimum_height, int& natural_height) const;
virtual void get_preferred_height_vfunc(int& minimum_height, int&
natural_height) const;
virtual void get_preferred_width_for_height_vfunc(int height, int&
minimum_width, int& natural_width) const;
virtual void on_size_allocate(Gtk::Allocation& allocation);
virtual void on_map();
virtual void on_unmap();
virtual void on_realize();
virtual void on_unrealize();
Trying again:)
Cheers,
Aitor.
Solved it...
I'll share the code in gitlab, when it's up and running
Thanks,
Aitor.
