Re: Callback to parent dialog

[Nalin Singal <nalinsingal yahoo co in>]

If you are writing this code in a Gtk::something class
or a class derived from one then you need to replace
"this" with "this->gobj()". And GtkWidget is correct.
Gtk::Widget is a Gtkmm object which is actually a
class wrapped around the underlying GtkWidget.
gtk_widget_toplevel() returns a GtkWidget* NOT a
Gtk::Widget*.  Also gtk_widget_toplevel() takes a
GtkWidget* not a Gtk::Widget*. This is the reason for
replacing "this". As someone else pointed out you are
mixing Gtk+ code and Gtkmm code (or C code and C++
code).
