little offtopic: multi-level signal handling

[Stefan Kost <kost imn htwk-leipzig de>]

hi hi,

how would one handle the following scenario properly in gtk?

we have a gui that has multiple views. when the user changes data signals are
emitted so that the other views can redraw.
Problem is, that when a new file is loaded such signals would be triggered
multiple times (because e.g. 20 items are added).

I basically see two ways to handle it, which both look not so nice:

#1 the loader code can set some flag (bulk-change) in objects that it changes.
this flag is checked before emitting signals

#2 the gui code can set a flag before invoking an action that does bulk-changes
and then signal-handlers ignore the signals when the flag is set

Hope it is understandable.

Ciao
  Stefan
