Re: Multiple threads and gtk_main()
Hi, Could the GAsyncQueue be configured to run a callback in the main thread when a element (or whatever gets pushed into it) is ready, just like one woud do with a GIOChannel ? It would be cleaner than a timeout or an idle function I think.

That would work with a timeout, but not with an idle function. Using g_idle_add() in this way would create a busy loop.

waveform display in gtk
Hi all, Is there a GTK widget to display audio or signal waveforms? If not, is there a related project in which such a widget is available?

Re: Multiple threads and gtk_main()
I'm new to gtk and still reading tutorials, but can we register a new signal to any global object (possiblely main window), thus call back function can be connected in the main thread and the signal can be emitted in other threads? --- Jonathan Winterflood [EMAIL PROTECTED] wrote: On 7/11/07, Gabriele Greco [EMAIL PROTECTED] wrote: Jonathan Winterflood wrote: Could the GAsyncQueue be configured to run a callback in the main thread when a element (or whatever gets pushed into it) is ready, just like one woud do with a GIOChannel ?

If you needed to display relatively short signals (a few seconds), something like GtkDatabox would work. GtkDatabox is not suited for long audio clips, since you'd have to only show the signal envelope after resampling, otherwise refreshing takes too long. -Jim ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
