I am trying to add a TextView instance to a Grid. But when I display the
window, it is
empty. The Grid examples I have seen add buttons to the grid and these work
fine
for me. But I don't understand the difference between adding a button and
adding
a TextView. If anyone can help me with this, I would appreciate it.
Here is my sample code (part of the constructor for my window):
set_child(m_grid);
Gtk::TextView tc;
Glib::RefPtr<Gtk::TextBuffer> tb = Gtk::TextBuffer::create();
std::string msg("cell 1,1");
auto it = tb->insert(tb->begin(), msg);
tc.set_buffer(tb);
m_grid.attach(tc, 0, 0);
m_grid.set_visible();
