The gtk_text_buffer_get_text() routine does *not* work.

No it's not. that url doesn't resolve (at least as far as the #id tag
goes). Additionally, your suggestion doesn't work either...

In both of these instances I get the following error:
Gtk-WARNING **: Invalid text buffer iterator: either the iter
ator is uninitialized, or the characters/pixbufs/widgets in the buffer have been
modified since the iterator was created.
You must use marks, character numbers, or line numbers to preserve a position ac
ross buffer modifications.
You can apply tags and insert marks without invalidating your iterators,
but any mutation that affects 'indexable' buffer contents (contents that can be
referred to by character offset)
will invalidate all outstanding iterators

Re: Getting text out of a GtkTextView
Hello, list!
The following link tells you how to get the contents of the
entire text widget as a string:
http://developer.gnome.org/doc/API/2.0/gtk/gtk-question-index.html#id2850623
GtkTextIter start, end;
GtkTextBuffer *buffer;
char *text;
buffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW (text_view));
gtk_text_buffer_get_bounds (buffer, &start, &end);
text = gtk_text_iter_get_text (&start, &end);
...use text...
g_free (text);
;) Just copy. It has to work, doesn't it?

Re: Getting text out of a GtkTextView
You've created two pointers to a GtkTextIter, but they don't point to a
valid GtkTextIter structure in memory. Here's what you probably meant to
do...
void insertCustomer( GtkWidget *customers )
{
GtkTextBuffer *specialBuffer;
GtkTextView *specialView;
GtkTextIter start;
GtkTextIter end;
gchar* *specialText;
specialView = lookup_widget(customers, "cust_instructions");
specialBuffer = gtk_text_view_get_buffer(specialView);
gtk_text_buffer_get_bounds(specialBuffer, &start, &end);
specialText = gtk_text_buffer_get_text(specialBuffer, &start, &end, FALSE);
g_print("Special Text: %s \n",specialText);
}

Anyway, I'm trying to get the text from the GtkTextView but only end up
with 'null' when I try to print it. Here is a code snipped:
void insertCustomer( GtkWidget *customers )
{
GtkTextBuffer *specialBuffer;
GtkTextView *specialView;

g_print("Special Text: %s \n",specialText);
}
I actually want to be able to insert that text into a database field but
it's not working.
Any help is appreciated.

Getting text out of a GtkTextView
I have a GtkTextView in one of my application windows; mainly because a
GtkEntry is only single width and I want text wrapping and so forth.
Anyway, I'm trying to get the text from the GtkTextView but only end up
with 'null' when I try to print it. Here is a code snipped:
void insertCustomer( GtkWidget *customers )
{
GtkTextBuffer *specialBuffer;
GtkTextView *specialView;
GtkTextIter *start;
GtkTextIter *end;
gchar* *specialText;
specialView = lookup_widget(customers, "cust_instructions");
specialBuffer = gtk_text_view_get_buffer(specialView);
gtk_text_buffer_get_bounds(specialBuffer, start, end);
specialText = gtk_text_buffer_get_text(specialBuffer, start, end, FALSE);
g_print("Special Text: %s \n",specialText);
}
I actually want to be able to insert that text into a database field but
it's not working.
Any help is appreciated.
