Examples based program that demonstrates the notebook page switch calling get_current_page segfault bug. (2.55 KB, text/plain)

Description Erik Ch. Ohrnberger 2002-12-13 18:27:40 UTC 
A method is connected to the Gtk::Notebook.signal_switch_page() signal
slot.  In this method there is a call to Gtk::Notebook.get_current_page().
 It is in the call to get_current_page() that a segfault is generated, and
crashes the application.

Comment 2 Daniel Elstner 2002-12-13 19:18:43 UTC 
line 78:
    notebook->signal_switch_page().connect(
		slot( *notebook, &AppWindow::NotebookPageSwitch ));

can't work since *notebook is not of type AppWindow.  This construct
should trigger a compile-time error -- you need to upgrade to a recent
libsigc++ because of a bug that allowed this kind of type-unsafety.
