someone please answer, clearing text in a GtkTextView!
I have a GtkTextView in a window used for data entry into a database. The text typed in the view gets put in the database no problem, but once the data entry has occurred, I want to clear the view so that the next screen of data can be input. Looking through the API, there isn't a "set text" function for this view (per se) like the GtkEntry widgets, except in the GtkTextBuffer. The other funcition in that widget is gtk_text_buffer_delete, which I called but I'm getting an error. Here's the code I was using to get the buffer, then delete it: /* the GtkTextView in this window requires a bit of extra work to get the text value stored in it. */ specialView = lookup_widget(customers, "cust_instructions"); specialBuffer = gtk_text_view_get_buffer(GTK_TEXT_VIEW(specialView)); gtk_text_buffer_get_bounds(specialBuffer, &start, &end); gtk_text_buffer_delete(specialBuffer, &start, &end); But here's the error I'm getting when I try to do that: (dispatcher:1523): 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 (dispatcher:1523): Gtk-CRITICAL **: file gtktextbuffer.c: line 1297 (gtk_text_bu ffer_delete): assertion `gtk_text_iter_get_buffer (start) == buffer' failed Then it segfaults. So I tried the set text call like this: gtk_text_buffer_set_text(specialBuffer,"", 0); but that makes my app segfault as well. Can anyone help? -- .''`. Carl B.

Do you want to clear the *view* (the GtkTextView) or the *model* (the GtkTextBuffer)? If the former, you want to remove the TextBuffer and replace it with a new one. If the latter, you just need to clear the buffer. Try something like: textbuffer.erase(textbuffer.start(), textbuffer.end()); for Gtkmm, or else for GTK+ (untested), try GtkTextIter start, end; gtk_text_buffer_get_start_iter(textbuffer, &start); gtk_text_buffer_get_end_iter(textbuffer, &end); gtk_textbuffer_delete(textbuffer, &start, &end); Both should have the same effect.
