Re: GtkTextView Questions -- please help! =]

Hi Raymond,

Thanks for replying. But I still have some issues, and I cant figure them out. I
was thinking if I showed you some code it would help:

1) As far as creating 2 textviews with the same hieght, I do this (but it ends
up with the first textview 1/3 the size of the second):

      table = gtk_table_new (1, 4, FALSE);
      gtk_container_add(GTK_CONTAINER(window), table);
     
      temp->display = gtk_text_view_new ();
     // gtk_text_view_set_wrap_mode(GTK_TEXT_VIEW(temp->display),  GTK_WRAP_CHAR);
      gtk_text_view_set_editable(GTK_TEXT_VIEW(temp->display), FALSE);
       
      
      temp->dispBuffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW (temp->display));
   
      temp->input = gtk_text_view_new();
      gtk_text_view_set_wrap_mode(GTK_TEXT_VIEW(temp->input), GTK_WRAP_CHAR);
      temp->typeBuffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW (temp->input));
      
      sw = gtk_scrolled_window_new (NULL, NULL);
      gtk_scrolled_window_set_policy (GTK_SCROLLED_WINDOW (sw),
GTK_POLICY_NEVER, GTK_POLICY_AUTOMATIC);
        
     

      gtk_paned_add1 (GTK_PANED (panel), sw);

      gtk_container_add (GTK_CONTAINER (sw), temp->display);   

     

      sw = gtk_scrolled_window_new (NULL, NULL);
      gtk_scrolled_window_set_policy (GTK_SCROLLED_WINDOW (sw),
GTK_POLICY_NEVER, GTK_POLICY_AUTOMATIC);

         

      gtk_paned_add2 (GTK_PANED (panel), sw);

      gtk_container_add (GTK_CONTAINER (sw), temp->input);

      gtk_table_attach (GTK_TABLE (table),
                        panel,
                        /* X direction */       /* Y direction */
                        0, 1,                   0, 3,
                        GTK_EXPAND | GTK_FILL,  GTK_EXPAND | GTK_FILL,
                        0,                      0); 


so quick explaination of the code, I have a paned widget, I create 2 scrolled
windows with textviews in them. I create them the same way, and add the to the
panel, then I add the panel to the table. You would think that the  size of the
scrolled windows would be the same.

2) I actually figured out this problem by sending the textview widget to the
function where i enter text into it, and used the gtk_text_view_scroll_iter or
something like that.

3) If you look in the code above, you will see the line:

gtk_text_view_set_wrap_mode(GTK_TEXT_VIEW(temp->input), GTK_WRAP_CHAR)

i was hoping that this would set the scrolled window to wrap text, however, it
does not. In this textview, users will type in text, and then once they hit a
button, it will go to the other textview. Just like a instant message (this is
actually what it is). But for some reason it doesn't work, and as text is typed,
it never wraps. I was wondering if you had any suggestions. Thanks for your help!
