Hello,


I'm trying to write a little Linux Console application with Ncurses. To=20
have an easier Window interface for my purposes I created an Window class=
=2E

1. How i can delete an existing windows + its content from the screen?
AFAIK it should work with clear(), but doesn't work, the window+content=20
is still on the screen

2. I don't get it work to have colored windows/text :/
Whats wrong in my class?

#I initialize ncurses with:
@scr =3D Ncurses.initscr() #init ncurses mode
Ncurses.raw()
Ncurses.noecho
Ncurses.cbreak
Ncurses.stdscr.keypad(true) '
Ncurses.start_color()
Ncurses.refresh

----
class Window=20

   include Ncurses
   attr_reader :height, :width
   def initialize(title, height, width, x, y)
     @title=3Dtitle
     @height=3Dheight
     @width=3Dwidth
     @x=3Dx
     @y=3Dy
     @win =3D Ncurses::WINDOW.new(height,width,x,y)
     refresh
     #Ncurses.init_pair(0, Ncurses::COLOR_RED, Ncurses::COLOR_GREEN);
   end
   def refresh
     @win.box(0,0)
     @win.mvaddstr(0, 1, " #{@title} ")
     @win.refresh
   end
   def clear
     @win.clear
   end
   def addtxt(txt)
       return if txt[0].nil?
       y=3D0
      #COLORS Test
         Ncurses.start_color()
         Ncurses.init_pair(0, Ncurses::COLOR_RED, Ncurses::COLOR_GREEN);
         @win.color_set(Ncurses::COLOR_PAIR(0),nil)
         @win.attron(Ncurses::COLOR_PAIR(0))
         Ncurses::attron(Ncurses::COLOR_PAIR(0))
      #/COLORS Test

       txt.each do |i|
         if i[1] =3D=3D :Bold
           @win.attrset Ncurses::A_BOLD
         else
           @win.attrset Ncurses::A_NORMAL
         end
           Ncurses::mvwprintw @win, y+=3D1, 1, i[0].to_s.chomp()
          end
     refresh
   end
   def delete
     @win.delete
   end
end

Fabian
