Yes, I checked and it does return 0 before gtk_main() has been called. I'll play around with it. Thanks for the tip.

VALA and GTK
Hi all: I am trying to find the best way to develop free software in the GNOME world . What do you think about VALA?. Actually c # is a great language and i do not like c + + or JAVA at all, but it is VALA a technology with future? For me, GObject it´s great, but with VALA is very quick when you want *Object-oriented programming in C.* -- MONO/ GTK # vs GTK + vs VALA :-\ In my work i am using Ruby / gnome, but only for very small things. We never can touch Qt :-D , hehe Greetings. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

g_array_copy how to?
Hi, Can somebody please tell me how can I write a function which returns a copy of a given GArray. The problem I am facing is how to identify the type of the data in the given array. Also I would like to know how can I pass type as an argument, like g_array_index does. Thanks, kaustubh Never miss a thing.

The sequence of operations is something like this: 1 * Init various GUI elements including the track treeview. 2 * Read the DB and append elements to the treeview. 3 * call gtk_main() and wait for events. Now, if the user quits between 2 and 3, it becomes an issue because gtk_main() hasn't been called yet and I can't check for the main loop. If gtk_main() has been invoked, I can check for the existence of the mainloop like this: while(gtk_events_pending()) if (gtk_main_iteration_do(FALSE)) return; Is spawning a thread and cooking up some simple synchronization scheme the only way to quit gracefully ? thanks, Sujith ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: GLib questions, GArray and GNode
Dear Jordan,
Thanks for quick answer. I am not very good in
extensive pointer programming. So it will be very nice
of you if you can clarify some more things.
1. Is the following function ok?
GArray* g_array_clone(GArray *array) {
int i;
GArray *clone = g_array_new(FALSE,FALSE,sizeof(long));
for(i=0;ilen;i++)
g_array_append_val(clone,(long)g_array_index(array,long,i));
return clone;
}
2. I want reconstruct a tree from a text file. For
that I need to iteratively read node information (node
names as a string) from the file and add the node to
the tree. In this case how can I add the string to the
->data?
Thanks in advance,
Kaustubh

Yes, just keep in mind to free any temporary data, and that garray2 will have to be freed by whatever needs the copy. 2. You can add anything as data (answers 3 also) data is just a pointer to the "actual data". to clarify.. no you cannot add an "int". but you can add a pointer to an int* or &int, string, GList, etc. 3. yes.. just add a pointer to your structure as ->data and typecast where needed. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

You might have some success if you use the low level mechanism:
http://library.gnome.org/devel/gobject/stable/gobject-Signals.html#g-signal-handler-block
and/or
http://library.gnome.org/devel/gobject/stable/gobject-Signals.html#g-signal-handlers-block-matched
and/or
http://library.gnome.org/devel/gobject/stable/gobject-Signals.html#g-signal-stop-emission-by-name
etc. That's all at the individual signal level, but probably the
behaviour you're trying to block is in a signal handler somewhere.
A different tack would be to desensitize ("grey out") the Widget, ie
http://library.gnome.org/devel/gtk/2.12/GtkWidget.html#gtk-widget-set-sensitive
though that's probably not "stop UI updates" like you asked.
