Hi Matthew,

Thanks for your explanation about the process of page switch. It is very
helpful for me. I want to recognize all malloc or new memory allocation
functions related with one tab page. I hope to log all this memory
allocation functions information related with this one tab no any other
tabs. So I need one concrete identification for each tab. I will look at
GtkNotebook widget.

Best Regards,
