Re: Cant get GtkTextBuffer from GtkTextView widget

["Tiberius DULUMAN" <tiberius duluman gmail com>]

The handler should be:

static void handler(GtkWidget *widget, GtkTextView *tview)
{
    GtkTextBuffer *buffer = NULL;
    GtkTextIter iterator;

    buffer = gtk_text_view_get_buffer(tview);
    g_assert(buffer != NULL);             <<< assert that it is not null
    gtk_text_buffer_get_end_iter(buffer, &iterator);   <<< pass an allocated
iterator
    gtk_text_buffer_insert(buffer, &iterator, "Info message", -1);
}
