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,
Pengfei

Hi Lex,

I have one question about tab switch in the geany. I know the different tab
has different doc->id. I think there is only one thread which manages all
tabs, right?  I wonder when we switch different tabs to edit the document.
How does geany manage or recognize different tabs? g_main_context_check
will be called in g_main_loop_run. Whether the data structure GMainContext
will include some information which can recognize the different tab?


 Hi,

I know you weren't addressing me, but you might want to look into GTK+, the event-driven GUI toolkit Geany uses. When user changes a tab, the GtkNotebook widget emits a signal telling Geany about the event, and then Geany asks the GtkNotebook for the widget contained in the selected tab page, which (eventually) contains the Scintilla widget, via the GTK+ widget hierarchy.

If you're trying to track down the control flow via GDB or other debugger, the event-driven model is going to send you on a wild goose chase through hell :)

FWIW, doc->id is basically not very useful, it just tells the index into some internal array of GeanyDocument objects, but is not unique to each document/tab per se (it gets recycled for new documents and such).

Cheers,
Matthew Brush
