Re: How would I use casting ?
Sorry I missed out the gtk_widget_show()API in program written in the mail. But actually in original program I have written it and even I tried writing gtk_window_maximize before gtk_widget_show()and after as well. But still it shows normal window and doesn't maximize it. I think then my window manager does not support it and unmaximizes it again as written in API help.

Hi, Dipak G Patil [EMAIL PROTECTED] writes: I asked just you because, you have said following method is not best way but neither told why nor suggested best way. And obviously such statement would make anybody confused. OK then, perhaps it's time to repeat it once more then. A widget doesn't have a GdkWindow until it is realized. If you want to understand why this is the case, then you should make yourself familiar with the basics of the X11 windowing system. In general you rarely ever need to access widget-window. An execption is for example when you are writing a custom widget and need to draw on the GdkWindow. However you must only ever draw in an expose_event handler anyway and widget-window will be valid then. If you need to access the window member outside an event handler (you may for example want to set a cursor), then you should connect to the realize signal or the configure event. The window will have been created when these signals are emitted. Sven ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

Its really a quite simple concept as long as you dont
include gtk+ floating references which are there to simplify
the programmers work and utterly confuse the newbie ;-)
When you allocate memory using malloc(), you free it with free(),
when you instantiate a GObject, you release it with g_object_unref().
the difference is that you dont know if that object is finalized or
not (finalize is just a fancy way of saying that the object is freed
and all the resources it occupied are actually released).
Generaly, an object is created with a reference count of one, this means
that the piece of code responsable for instantiating the object owns it
(that reference belongs to the allocating code), other pieces of code
may depend on that objects existance for a finate amount of time, during that
time it will hold another reference to it.
Take signal emmission for example, the objects own code might look like
this:
if (signal condition) {
g_object_ref(object);
g_signal_emit(...); // call all interrested signal handlers
g_object_unref(object);
}
What if the first signal handler is the owning entity and
decides for some reason to release the object, and that the second
signal handler down the chain gets called ? if there wasn't an
extra reference owned by the object itself, chances are the
second second signal handler would cause the program to segfault
(reference to some non-allocated memory space or something).
Anyhow, I think there is plenty of documentation on this subject
and it is inapropriate for a tutorial, as reference counts are
more of an important detail to take into account than a task to
perform.
I hope I have enlightened you on this subject though ;-)
For more detailed documentation on the object system, you
should read: http://www.le-hacker.org/papers/gobject/index.html

Re: Odd GtkTextView behavior
Hi Havoc, I would imagine it would be a useful fix as from what I can see at the moment there is no way to change the default style of the TextView so that newly inserted characters can use the current style. This means that when you are typing new text you always have to set the current style to each new character, which of course is not good. Is there a way to change the default style of the TextView so that I can do it this way instead of applying tags to the newly typed characters each time. Thanks for your time Ian King Havoc Pennington wrote: On Thu, 2004-07-08 at 18:51, Ian King [ES] wrote: I've noticed when using the GtkTextView widget that when it is being used in normal operation, for things such as a word processor or code editor, when the caret is placed at the end of a word and text is entered on the keyboard, the control doesn't print the new text in the style of the previous character. Is this expected behavior or a bug? This can be tested by using the TextView demo launched from gtk-demo. It is expected, though it's the kind of thing that should probably be changed in GTK+ 3.0 (i.e. if we ever break the ABI again). Apps such as gedit track the current style and apply it to newly-inserted text themselves, I believe. One ABI-compatible patch might be to add a sticks to newly inserted text property to GtkTextTag - don't know if that would work, but if someone coded the patch and put it in bugzilla it seems like a reasonable feature. We'd want to cc the gedit guys and other heavy TextView users on the bug and see if they think it's a useful fix.
