wxruby users - Nov 2007 - Issues adding sub-menu items

Hello All,

I''m new to the list and to Ruby.

I was trying to use one of the examples as a skeleton for something that
I''m working on.

I''m currently stuck when it comes to adding another item to the
sub-menus.
I have a menu item by the name of "Tools" and I would like to add a
sub-menu item called "Find Unique Fields" but it doesn''t show
up when I
try to run it.

If I add a Wx::ID_UNIQUE and a handle for the event the program fails.

What do I need to do or what I''m I missing. I appreciate your response.


Thanks,


Glenn

class HL7Query < Wx::Frame
  def initialize(title)

    super(nil, :title => title, :size => [ 850, 600 ])


    menu_bar = Wx::MenuBar.new

    # The "file" menu
    menu_file = Wx::Menu.new
    menu_file.append(Wx::ID_EXIT, "E&xit\tAlt-X", "Quit this
program")
    menu_bar.append(menu_file, "&File")

    # The "Tools" menu
    menu_tools = Wx::Menu.new
    #menu_tools.append(Wx::ID_UNIQUEFIELDS, "Find Unique Fields",
"Find
Unique Fields")
    menu_tools.append(nil, "Find Unique Fields", "Find Unique
Fields")
    menu_bar.append(menu_tools, "Tools")

    # The "help" menu
    menu_help = Wx::Menu.new
    # Using Wx::ID_ABOUT default id means the menu item will be placed
    # in the correct platform-specific place - eg on OS X
    menu_help.append(Wx::ID_ABOUT, "&About...\tF1", "Show
about dialog")
    menu_bar.append(menu_help, "&Help")

    # Assign the menubar to this frame
    self.menu_bar = menu_bar

    # Create a status bar
    create_status_bar(2)
    self.status_text = "Welcome to HL7Query!"

    # Set it up to handle menu events using the relevant methods
    evt_menu Wx::ID_EXIT, :on_quit
    evt_menu Wx::ID_ABOUT, :on_about

  def on_quit
    close()

Wx::App.run do

  frame = HL7Query.new(":::HL7Query:::")
  frame.show

Your example (the row that wasn''t commented out) had nil as the menu 
item id, which will fail. Either you have to supply your own valid ID 
value (starting from 100 going upwards is a good idea) or you use 
Wx::ID_ANY as the ID and you''ll get an automatically assigned id (use 
get_id for the returned menu item object to know the ID).

You have many ways to go here. Since you seem to choose to set up IDs 
yourself, first try a numerical value (for example 101) so you see how 
it works:
       menu_tools.append(101, "Find Unique Fields", "Find Unique
Fields")
...and set up the menu item event handler...
       evt_menu 101, :on_unique_fields
...and then create the event handler method...
       def on_unique_fields
          p "on unique fields menu item selected"
       end

Now, replace the number 101 with ID_UNIQUE:
ID_UNIQUE = 101
...
menu_tools.append(ID_UNIQUE, "Find Unique Fields", "Find Unique
Fields")
...
evt_menu ID_UNIQUE, :on_unique_fields

Please note that the Wx:: prefix should NOT be used prior to your own 
constant names - you don''t want your own constants to interfere with
the
wxRuby name scope.
