Ruby Forum Ruby-Gnome 2 > Hiding a scroll bar

Hello,

I'm writing a application where I have a textview inside a 
scrolledwindow. Is it possible to hide the vertical scrollbar?

I tried scrolledwindow.set_policy(Gtk::POLICY_NEVER) but then my 
textview grows as the text grows. I want that my textview to behave like 
it there was a scrollbar, I just want it invisible (the user can go up 
and down in text with PageUp/Down).

I also tried scrolledwindow.vscrollbar.hide, but that doesn't do 
nothing.

Regards,

André

Use GtkWeidget#set_size_request.

  scrolled_window = Gtk::ScrolledWindow.new
  # Ruby/GLib2 >= 0.17
  scrolled_window.set_policy(:automatic, :never)
  # Ruby/GLib2 < 0.17
  #  scrolled_window.set_policy(Gtk::POLICY_AUTOMATIC,
  #                             Gtk::POLICY_NEVER)

  text_view = Gtk::TextView.new
  text_view.set_size_request(200, 300)

  scrolled_window.add(text_view)

Thank you very much for this info, this behavior was exactly what I was 
looking for!

However... I need my text box to be resizeable. Is there any way I can 
get this behavior wihtout using set_size_request on the text box?

Thank you in advance,

André

Is it good enough that resize top level window?
Could you show your example script?

Try to imagine a text editor such as Wordpad. If I use set_size_request 
in the main textview, I won't be able to resize my window by making it 
smaller. Am I right?

What about text_view.set_size_request(0, 0)?

Could you show an example script that reproduces the
problem?

Oh, well, I just haven't thought of that :-) I only thought of something 
like text_view.set_size_request(400, 300).

Thank you very much for your direction and patience!
