-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all,
I have an application where I'm making use of animated gifs on a GtkTextBuffer. I set a timer (g_timeout_add()) to remove the animated character after a small period of time (10 secs in this case). The argument to the timer callback includes a pointer to the text buffer GtkTextChildAnchor in front of where I inserted my animation. The idea is that inside the timeout, I insert a static copy of the gif, and do a gtk_text_buffer_delete() of the iter's before and after the animation. This works about 99.999% of the time. In some rare circumstances, by the time that the timer callback is called, the GtkTextChildAnchor has been deleted. To guard against this, I tested the GtkTextChildAnchor with GTK_IS_TEXT_CHILD_ANCHOR(), but on occassion, I will get a segfault on the GTK_IS_TEXT_CHILD_ANCHOR() (the address of the GtkTextChildAnchor is still a valid address). I'm thinking that the GtkTextChildAnchor has been deleted, the memory used for something else, and the GTK_IS_TEXT_CHILD_ANCHOR() is seg faulting as a result. Question: how might I avoid this seg fault situation ? Will "GTK_IS_WIDGET()" help to determine if the GtkTextChildAnchor is still alive before testing it with GTK_IS_TEXT_CHILD_ANCHOR() ? or is there a better way of doing this ?
