Hi again,
Sorry to bother you guys again. I've been at this for a few days now and
I really can't figure it out. What I'm trying to do is have a constant
string or label in a text view buffer. Something like what
gnome-terminal has with the username@host. What I've tried to do so far
is connect to the textview signal_event and look for the backspace or
delete key. That worked kind of, but, the user can still add text then
delete the constant text. Here is the code for that:
|//in constructor
txt_view_i_.signal_event().connect(sigc::mem_fun(*this,
&MainWindow::inputEvent));
//function
bool MainWindow::inputEvent(GdkEvent* event)
{
if((event->key.keyval== GDK_KEY_BackSpace|| event->key.keyval== GDK_KEY_Delete)
&& buffer_input_->get_char_count() < 3)
return true;
return false;
}|
I also tried adding a label to text view, but the same problem araised
again, the user can delete the label. Here is the code for that:
|Gtk::TextBuffer::iterator it= buffer_input_->get_iter_at_line(1);
Glib::RefPtr<Gtk::TextChildAnchor> refAnchor=
buffer_input_->create_child_anchor(it);
Gtk::Label* lbl= Gtk::manage(new Gtk::Label(">"));
txt_view_i_.add_child_at_anchor(*lbl, refAnchor);

||Any suggestions to what I can do?
Thank you all very much
Tim O.
