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+
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).
