Thank you on all counts!
The main problem was my callback (duh! I forgot the "GtkWidget *w" argument!);
I also changed all
my "gtk_signal_connect()" calls to g_signal_connect()", and all my
"gtk_signal_connect_object()"
to g_signal_connect_swapped()".
It works fine now - thanx again!

Well, thanks for the correction. I will have to go back through my
projects to understand why I thought that.

Subject: Reference to a C++ object in GTK+ callbacks
Hi -
I'm using the GTK+ 2.6.4 that came with Suse 9.3. I'm coding in C++, but using
the "raw" GTK+ C
libraries.
I'm trying to pass a pointer to one of my C++ classes into a callback, so that
I can c

I'm doing similiar for a game I'm making.

AnimationFile must have a public virtual function void start(), and
m_animation must actually point to an Hbafile, so that when you cast the
void* to AnimationFile* it's going to find a vtable slot for start().
If AnimationFile's start() isn't declared virtual, it won't go through
the vtable.
With
How about trying gdb, seeing what the value of ani is at the time of the
crash. How about a backtrace?
It's hard to debug your problem as described. But I have a feeling with
some minimal gdb'ing you can find the bug yourself.
