Description Chris Sherlock 2004-04-24 19:21:20 UTC 
gtk_widget_reparent_subwindows fixed to prevent warning by gcc about it breaking
strict aliasing rules. Happens because gdk_window_get_user_data is expecting
parameter 2 to be a gpointer*, however it's getting a GtkWidget.

Fixed by creating a gpointer variable pchild for use in
gdk_window_get_user_data, then assign it's address to GtkWidget *child.

There's been a lot of discussion about these kinds of warnings and there's a
general bugreport for them in bug #122777. Should this be closed as a duplicate
of that one?
Comment 3 André Klapper 2006-10-07 16:01:38 UTC 
no feedback, closing as duplicate.
