CMS help [RESOLVED]

I am currently working on making a CMS for my game but i kinda hit a wall in one respect. I would like to display my skills on several 'pages', by this i mean that i want to show the first 6 skills in the window, then when right is pressed it will draw the next 6 items, i just need to know how to make the left/right page switching work....

EDIT:
after a bit of fiddleing i figured it out: i added a parameter to the initialize method and used global variables to keep track of what page i was on, then added conditions to whether left or right was pushed that change the page variable and dispose of the menu and re-initialize it with the new page #.

here's the old code:

Code: [Select]

class Test_Menu_9 < Window_Selectable
  def initialize(actor)
    super(0, 0, 450, 235)
    @actor = actor
    @item_max = 6
    refresh
    self.index = 0
  end
   
  def skill
    return @data[self.index]
  end
   
  def refresh
    if self.contents != nil
      self.contents.dispose
      self.contents = nil
    end
    @data = []
    for i in 0...@actor.skills.size
      skill = $data_skills[@actor.skills[i]]
      if skill != nil
       # if @actor.skill_can_use?(skill.id)
          @data.push(skill)
       # end
     end
     @column_max = ((@data.size - 1) / 6) +1
    end
    # If the number of items is not 0, it draws up bit map, drawing all item
    @item_max = @data.size
    if @item_max > 0
      self.contents = Bitmap.new(width - 32, row_max * 32)
      self.contents.font.name = $fontface
      self.contents.font.size = $fontsize
      for i in 0...@item_max
        draw_item(i)
      end
    end
  end
 
  def draw_item(index)
    skill = @data[index]
    x = 0
    y = index * 32
    rect = Rect.new(x, y, self.width / @column_max - 32, 32)
    self.contents.fill_rect(rect, Color.new(0, 0, 0, 0))
    bitmap = RPG::Cache.icon(skill.icon_name)
    self.contents.blt(x, y, bitmap, Rect.new(0, 0, 24, 24), 255)
    self.contents.draw_text(x + 30, y, 204, 32, skill.name, 0)
    self.contents.draw_text(x + 200, y, 48, 32, skill.sp_cost.to_s, 2)
  end
   
end


Code: [Select]

class Test_Scene_2
#BLOCK 1
def main
   @window_1=Test_Menu_7.new
   @window_8=Test_Menu_8.new
   @window_8.x=190
   @window_3=Test_Menu_11.new($Character_Id_I_Am_Working_With)

     $game_system.se_play($data_system.cancel_se)
     $scene = Scene_Map.new
   end
   
  end
end

and the new code:

i do realize it might be hard to see what i'm saying because i'm not good at explaining....so please tell me if you don't understand! I've attached the demo of what it does.
