Re: Multiline Textbox...

[hpnadig <hpnadig lycos co uk>]

why were they deprecated? gtk_text widget is simpler than the
gtk_view...

I had problems retrieving the text from text_buffer using text_iter...

what should I do to define the text range from start to the end of the
text view?

I mean, start iter will have 0 and end iter will  have '?'?

I tried using both
gtk_text_buffer_get_text(.. ...)
&
gtk_text_buffer_get_slice(... ...)

but I keep getting text stored *initially* on the buffer.. :(

Here's my code snippet:

view = gtk_text_view_new ();
// my text view..

                buffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW (view));

                gtk_text_buffer_set_text (buffer, "My test Message from code..",
-1);



                gtk_text_view_set_left_margin (GTK_TEXT_VIEW (view), 30);

                gtk_box_pack_start (GTK_BOX (GTK_DIALOG (popup)->vbox),
                        view, TRUE, TRUE, 0);

                gtk_text_buffer_get_start_iter  (buffer, &start);
                gtk_text_buffer_get_end_iter    (buffer, &end);
                
                gtk_text_buffer_get_iter_at_offset (buffer, &start, 0);
                gtk_text_buffer_get_iter_at_offset (buffer, &end, 1000);
                
                // here's my problem-1 :: I gotto set the iter to cover all the text
typed in... 

                mlhdr.body = gtk_text_buffer_get_text (buffer, &start, &end, FALSE);
                //mlhdr.body = gtk_text_buffer_get_slice (buffer, &start,
&end,                                           FALSE);

( I tried even the second one... )
               gtk_widget_show (view);


Now, when I run the code & I type something deleting the text I've set
initially, I'm unable to *retrieve* it in my mlhdr.body.. :(

instead the same thing  keeps appearing...
