Re: delete_event

["Pavlo Korzhyk" <pavlo korzhyk gmail com>]

prefs_diag->delete_event().connect( sigc::ptr_fun(on_prefs_cancel_btn_clicked) );

However, the compiler said:

error: 'class Gtk::Dialog' has no member named 'delete_event'

The problem is that the dialog's X button has to be clicked twice to close the dialog.

According to my gtkmm documentation you must use widget->signal_delete_event
()
If this is not the solution - try explicitly convert prefs_diag to Widget*.
