Re: Getting parent Gtk::window

[ilkapo <ilkapo tiscali it>]

I use (Gtk::Window&)(*this->get_toplevel()) from a child widget for
display dialogs, for example:

// Display error message
Gtk::MessageDialog err_dialog( (Gtk::Window&)(*this->get_toplevel()),
	_("Unexpected exception"), false, Gtk::MESSAGE_ERROR );

err_dialog.set_secondary_text (e.what());
err_dialog.run();

in this way you don't need to disable sensitivity.
