g_idle_add() used for scrolling of text view to the end iter
Hello, In message log window i used g_idle_add() method for the purpose of scrolling to the end iter. During progress bar it works fine for the hard disk but when i goes to work on FTP there is some warnings across "word_wrap" and "wide_margins" in Log window during progress. Any body can help me out for this. How i can scroll window automatically to end iter when messages put on log window during process.

RE: Hello and win32 g_io_channel help needed
Failing this method I am moving to have my platform specific code handle the send and receiving, however I would still really like to use some kind of a callback like g_io_add_watch. I can easily achieve this under Linux with a little re-organisation to separate out the platform specific portions. Does anyone have a fairly straightforward approach to do the same under windows? If I cannot add a watch to the serial port I am afraid I may have to either fake it with a poll?

At your class_init you should peek (g_type_class_peek_parent, using
your class pointer as parameter) a pointer to your parent class and
keep it in a global storage, accessible to your finalize.
Then, in your finalize method you call the finalize method on this
pointer you just got from peek_parent, something like:
G_OBJECT_CLASS(parent_class)->finalize(pointer_to_the_object_being_finalized);
I hope this helps.

Hey Yeti, since you're on the subject of object destruction, could you explain me the difference between the finalize and dispose methods ? I use finalize for everything but I believe I should be using dispose somewhere, it wouldn't exist if it were useless...I guess :) Thanks, Alexandre Moreira. > > Yeti > > -- > http://gwyddion.net/ > ___ > gtk-list mailing list > gtk-list@gnome.org > http://mail.gnome.org/mailman/listinfo/gtk-list > ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

Aha again! I guess I can free private members in the same method as well?
static void
neural_net_finalize (GObject *object)
{
NeuralNet *nn;
g_return_if_fail (IS_NEURAL_NET(object));
nn = NEURAL_NET(object);
g_free(nn->priv->weight_h);
g_free(nn->priv->weight_o);
g_free(nn->priv->bias_h);
g_free(nn->priv->bias_o);
g_free(nn->priv->filename);
g_free(nn->priv);
g_message("This is the finalize method and I've freed the instance
members!\n");
}
static void
neural_net_class_init (NeuralNetClass *klass){
GObjectClass *gobject_class = G_OBJECT_CLASS (klass);
gobject_class->finalize = neural_net_finalize;
g_type_class_add_private (klass, sizeof (NeuralNetPrivate));
}
I think this looks ok, doesn't it? No, wait a minite What about the
parent? This class has GObjectClass as parent, how do I call it's finalize?

When the reference count reaches zero and the object is finalized, its finalize() method is called. And that's where you should free any possibly allocated memory. Remember to chain up parent class finalize() method in your finalize(). > I see a pointer to a func in the info struct called base_finalize and > another called class_finalize, but these seems to be used for cleaning > up when I have base_init and class_init.

'make' does not detect anything. The file that is being compiled does a little consistency check - it makes sure that the type of iconv header it has is consistent with the type of iconv that configure said it is supposed to be building with. 'configure' does try to detect the type of iconv. It evidently determined that your system had a non-GNU (native) iconv. But when the actual compilation happened, it went "whoops, this isn't supposed to be a GNU iconv header we have problems." It looks like your iconv library and the iconv header that the compiler finds don't match, most likely. Either that, or there's something else weird with your iconv & build setups. > So, what is the point in having such a configure script - 'configure' > is supposed to detect such things. Things like this are what configure options are for - to guide configure along when it doesn't make the right choice. It is neither practical nor, in many cases, possible for configure to provide a 100% guarantee that its success will imply a successful 'make'. It is not intended for it to provide such a guarantee. It merely tries to configure the software and sets up the Makefiles - if it couldn't make sense of your setup, it may not create appropriate Makefiles. It can't detect every possible contingency. It did reasonable checks to see which iconv your system has, and then that turned out to be inconsistent. In this case, it may be practical to add a test. That's up to the GTK+ devs. But in general, asking configure to detect every possible 'make' problem is essentially asking it to try to compile the program. That's make's job. And you only want to run 'make' once. - Michael -- Michael Ekstrand Research Assistant, Scalable Computing Laboratory Goanna, compute cluster and InfiniBand network monitor tool: http://www.scl.ameslab.gov/Projects/Monitor/ ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
GObject: Freeing memory of instance members?
Hi, I've just started to use GObject, and I think I understand most of it by now. There's still some questions remaining. Here's one: I have an instance struct that has a pointer to a some data that's dynamically allocated in a method. How can I free this memory when the object is finalzed? Is this done automatically in g_object_unref() (when refcounter is zero) ? -Øystein PS: I see a pointer to a func in the info struct called base_finalize and another called class_finalize, but these seems to be used for cleaning up when I have base_init and class_init. ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
