Re: GList strange behavior
Hi. Not sure what is troubling you here. GList is represented by pointer to first element or NULL if list is empty. And when you append items to the list, the address of the list stays the same, since first element of the list is unchanged (exception to this is when append first element to an empty list). Some code to explain some things: GList *list = NULL /* Empty list */ list = g_list_append (list, GINT_TO_POINTER (1)); /* Add first element, list points to some ADDR1 */ list = g_list_append (list, GINT_TO_POINTER (2)); /* Add second element, list still points to ADDR1 */ ...

getting the icon pixbuf for a file
Hey I am trying to get the icon bitmap for a file and insert it into a TreeView widget - That is the pixbuf for the mime-type of a file. Is there any examples of doing this in plain C using GTK/GLib? I am satisfied with an example that work in Linux - Win32 isn't equally important to me.

I think you'll want gtk_widget_render_icon() function [1]. This will use current theme settings to load proper icon and render it. For icon names, you can consult gtk-demo application that features icon browser.

gi._glib.GError: Invalid object type `VteTerminal'
Hey list, I've created a window through Glade 3.12.1 which contains a VTE widget within one of its sizers. It looks fine in Glade, but when I attempt to call the builder's add_from_file(Gooey.glade), I get the following error at runtime: $ ./Main.py Traceback (most recent call last): File ./Main.py, line 194, in module navigator = NavigatorApp() File ./Main.py, line 48, in __init__ self.builder.add_from_file(../Gooey/Launcher.glade) File /usr/lib/python3/dist-packages/gi/types.py, line 43, in function return info.invoke(*args, **kwargs) gi._glib.GError: Invalid object type `VteTerminal' I am using Python 3.2.3 with binding for Gtk+ version 3.4.2. This is strange because I am pretty sure I am importing the necessary modules prior to loading with builder via the following: from gi.repository import Gtk, Gdk, GObject from gi.repository import Vte, GLib Any help is appreciated. I'm finding the documentation on programming Gtk+ 3 via Python 3 scant. Not to mention distros compounding the difficulty frequently with old packages / bindings. Something that might help would be a simple minimal that instantiates a Glade defined VTE widget using Python 3 / Gtk+ 3.

Re: GList strange behavior
Hi, Seem you did not read my reply clearly. I told you the behaviour of g_list_append() and g_list_last() there. Okay, so your question is ( So, why g_list_append() dont' return me newly created list??? If you pass NULL pointer to first arg of g_list_append() it will returns a newly created list for you, save the address to the return pointer. If you pass non NULL pointer (already created list) to first arg of g_list_append() it will ALWAYS return the HEAD of the list and will not create a new list. It's better for you to read GList implementation source code. (glist.c) to fully understand how it work. Regards.

It's clear because 0x830f080 was the location of first list and 0x832c610 is the last appended list. g_list_prepend() return to the start of the list, g_list_last() return the last of the list (address). in test_glist() First you call temp = g_list_insert(test, ...), test = NULL, save the list to temp pointer to GList, second, you call temp = g_list_append(test, ...), nothing wrong with that code! BUT if you suppose to insert 2nd list here, then you are wrong. Because, test is STILL NULL. It returns the newly allocated list again, that's why it's differ. You should call call temp = g_list_append(temp,...) or to insert the next list. In real program, i need to get newly created list pointer in function like button_cb(), but don't know how to do it.

But I don't know where to copy the gtk+ and pygobject files to the right places to make it all work. Can someone tell me what to do?
