Forum: wxRuby listcontrol problem

trying to create a list control, filling with data, but it wont scroll
vertically or respond to mouse click.
-------------------------------------------
require 'rubygems'
require 'wx'
include Wx

class MyFrame < Wx::Frame
    def initialize()
        super(nil,-1,'Wristband Manager',:size => [300,400])
        @my_panel = Panel.new(self)
        show()
    end
end

class MasterList < Wx::ListCtrl
  def initialize(parent)
     super(parent,:size => [250,200],:style => Wx::LC_REPORT)
     create_layout
     add_entries
   end

  def create_layout
     self.insert_column(0, "Name")
     self.insert_column(1, "Courses")
     self.insert_column(2, "Band")
     self.set_column_width(0,100)
     self.set_column_width(1,25)
     self.set_column_width(2,50)
  end

def add_entries
    name = 'Test01'
    50.times do |idx|
       item0 = Wx::ListItem.new
       item0.set_text(name)
       item0.set_column(0)
       item0.set_id(idx)
       self.insert_item(item0)

       item1 = Wx::ListItem.new
       item1.set_text("15")
       item1.set_column(1)
       item1.set_id(idx)
       self.set_item(item1)

    item1 = Wx::ListItem.new
       item1.set_text("Green")
       item1.set_column(2)
       item1.set_id(idx)
       self.set_item(item1)
    name.succ!
    end
   end


end

class MyApp < App
    def on_init
        frame1 = MyFrame.new
    MasterList.new frame1
    end
end

MyApp.new.main_loop()

Okay, I'm noticing a few things here:

1.
include Wx # if you have this, you don't have to have Wx:: in front of
Wx classes or modules

2.
# in MasterList#add_entries
item1 = Wx::ListItem.new
item1.set_text("Green")
# ...
name.succ!
end
# you might want to find a different local name for this ListItem, since
it might be interfering with the one above it, unless that's what you
intend.

3.
# in My_App#on_init
MasterList.new frame1 # you might want to create the master list within
frame1, and set parent to self


If those don't do anything, let someone else tell you what to do.

Thanks, #3 did the trick!

No prob. Generally, you want to create window object within the
initialize of the parent object. Keeps problems from happening.
