You will want to check out a piece of source from the GTK+ demo application at http://cvs.gnome.org/viewcvs/gtk%2B/demos/gtk-demo/hypertext.c?rev=1.6&view=markup

thank u very much
it is very useful to me
but a small problem is
when i move the cursor on to hypertext.the cursor will not changing to the hand symbol
that's y iam unable click there.
i found that iiam not using the below function properly

g_object_set_data (G_OBJECT (tag), "page", GINT_TO_POINTER (page));.
this is the line from the code ur given.
how can i handle thid line in my code.
my code is
void
on_button1_clicked (GtkButton *button,
gpointer user_data)
{

gtk_text_buffer_get_end_iter( buffer1, &end );
gtk_text_buffer_place_cursor (buffer1, &end);

GtkTextTag *tag;

tag = gtk_text_buffer_create_tag (buffer1, NULL,
"foreground", "blue",
"underline", PANGO_UNDERLINE_SINGLE,
NULL);
g_object_set_data (G_OBJECT (tag), "page", GINT_TO_POINTER (page));
gtk_text_buffer_insert_with_tags (buffer1,&end, "www.google.com", -1, tag, NULL);

}

You need to check out the do_hypertext() function for changing the cursor. You have to create a new cursor with gdk_cursor_new(). Also, you're skipping a lot of steps it seems. I would recommend going through the whole demo and make sure you understand what is going on before you start coding yourself.

All the line you asked about is doing is converting an integer into a pointer so it can be stored on the object's data table. You see, every object can store pairs of strings and pointers. However, since an integer is not easily converted into a pointer, GLib provides a function for this. You can convert it back with GPOINTER_TO_INT().

you're probably just going to want to search through the buffer for both patterns. Things like http://, https://, file://, etc should force a url and www should be an afterthought.
