I'm not sure what is a correct way to show a buffer text.
I think we should call show_insert_position() in handle().
In the following example, TextDisplay shows its buffer text
when handling an event FOCUS.

=== example.rb ==
require 'fltk'

class MyTextDisplay < FLTK::TextDisplay
  def handle(e)
    case e
    when FLTK::FOCUS
      show_insert_position()
      return true
    else
      return false
    end
  end
end

w = FLTK::Window.new(0,0,200,200){
  d = MyTextDisplay.new(200,200)
  b = FLTK::TextBuffer.new(100)
  b.text = "this is a buffer text."
  d.buffer = b
  d.insert_position(0)
}
w.show
FLTK::run()
