Else one problem.

3) I create an application by Ctrl-C from one of lessons:

--------

require ''wx''
include Wx

class MyFrame < Frame
  def initialize()
        super(nil, -1, ''My Frame Title'')
        # First create the controls
        @my_panel = Panel.new(self)
        @my_label = StaticText.new(@my_panel, -1, ''My Label
Text'',
DEFAULT_POSITION, DEFAULT_SIZE, ALIGN_CENTER)
        @my_textbox = TextCtrl.new(@my_panel, -1, ''Default Textbox 
Value'')
        @my_combo = ComboBox.new(@my_panel, -1, ''Default Combo
Text'',
DEFAULT_POSITION, DEFAULT_SIZE, [''Item 1'', ''Item
2'', ''Item 3''])
        @my_button = Button.new(@my_panel, -1, ''My Button
Text'')
        # Bind controls to functions
        evt_button(@my_button.get_id()) { |event| 
my_button_click(event)}
        # Now do the layout
        @my_panel_sizer = BoxSizer.new(VERTICAL)
        @my_panel.set_sizer(@my_panel_sizer)
        @my_panel_sizer.add(@my_label, 0, GROW|ALL, 2)
        @my_panel_sizer.add(@my_textbox, 0, GROW|ALL, 2)
        @my_panel_sizer.add(@my_combo, 0, GROW|ALL, 2)
        @my_panel_sizer.add(@my_button, 0, GROW|ALL, 2)
        show()
    end

    def my_button_click(event)
        # Your code here
    end

end

class MyApp < App
  def on_init
    MyFrame.new
  end
end

MyApp.new.main_loop()

-------

I run it, but it window doesn''t open. In command prompt all work fint, 
but doesn''t open. What''s matter?

First off, this is correct in the code, till you get to your on_init method.
 I can tell you, that your Window is being created, and everything, but your
not showing it to the user.  There''s two ways in which you can do this.

The first, is to simply do: MyFrame.new.show()  Which will show your frame
to the user, after it is created.
The second, is to store the instance of your Window in a variable, and call
show in it, like this:
myframe = MyFrame.new
myframe.show

In both cases, you need to call the show method on your Frame, in order to
have your frame actually be displayed.  It isn''t done automatically,
cause
there may be times, where you want to create a window, but not show it, in
such cases as having a Tray Icon on Windows / Linux, and a Dock Icon on OS X
(EG The Bottom bar.)

hth with this one,

Mario

1.jpg) This is the cause of the fact that in your XRC Design, you do not
have a root Layout manager, meaning that the window needs to have a
VerticalSizer or a HorizontalSizer as the root item, in order to manage
layouts of all the controls in your window, otherwise, you have to do the
management of the layout yourself, meaning you need to keep tabs on the
window sizes, and control positions, and re-positioning your controls
yourself.  This also means that wxWidgets will not manage the window size,
and therefore, will allocate the minimal size for your window, which gives
you the issues you are seeing in 1.jpg.

This is an issue with Ruby 1.9.1, they made String where it is no longer
Enumerable, meaning that there is no .each method, that will parse through
each actual line of text in the code, as is done in Ruby 1.8.  I will see
about getting a new gem built, with a patch to fix that soon.

Thanks. Now I''m a new wx''er.

BTW, Misha on russian equivalent Michael in english :)

How you do the letters green?

1) I create forms now in DialogBlocks 4.39 (next - DB). If I do not 
create a menubar, it''s OK. If I add it, I need to change a PLATFORM 
value on it from any to some. It''s normal?

2) Conversion is normal in DB - in my opinion, the question is closed.

3) I copy code, but it not works:

------

require ''wx''
include Wx

class MyFrame < Frame
  def initialize()
        super(nil, -1, ''My Frame Title'')
        # First create the controls
        @my_panel = Panel.new(self)
        @my_label = StaticText.new(@my_panel, -1, ''My Label
Text'',
DEFAULT_POSITION, DEFAULT_SIZE, ALIGN_CENTER)
        @my_textbox = TextCtrl.new(@my_panel, -1, ''Default Textbox 
Value'')
        @my_combo = ComboBox.new(@my_panel, -1, ''Default Combo
Text'',
DEFAULT_POSITION, DEFAULT_SIZE, [''Item 1'', ''Item
2'', ''Item 3''])
        @my_button = Button.new(@my_panel, -1, ''My Button
Text'')
        # Bind controls to functions
        evt_button(@my_button.get_id()) { |event| 
my_button_click(event)}
        # Now do the layout
        @my_panel_sizer = BoxSizer.new(VERTICAL)
        @my_panel.set_sizer(@my_panel_sizer)
        @my_panel_sizer.add(@my_label, 0, GROW|ALL, 2)
        @my_panel_sizer.add(@my_textbox, 0, GROW|ALL, 2)
        @my_panel_sizer.add(@my_combo, 0, GROW|ALL, 2)
        @my_panel_sizer.add(@my_button, 0, GROW|ALL, 2)
        show()
    end

    def my_button_click(event)
        # Your code here
    end

end

class MyApp < App
  def on_init
    MyFrame.new
  end
end

MyApp.new.main_loop()

myframe = MyFrame.new.show()

---------

There isn''t a .xrc file in this folder. It''s only .rb file. It
doesn''t
work...

Can you give me some working simple window code to Copy-Paste in .rb 
file as example of ruby-GUI-application.

Sorry for my english, Misha.

Into the installation of wxruby gem, you can find many examples to try on.

This code:

#!/usr/bin/env ruby
require ''rubygems''
require ''wx''

class MyApp < Wx::App
   def on_init
     @frame = Wx::Frame.new( nil, -1, "Application" )
     @frame.show
   end
end

app = MyApp.new
app.main_loop
app.show

Doesn''t work. It show only command prompt with ruby, which close after 
working code. I didn''t see GUI window. Why?

Maybe I don''t install something? What I must install to wxruby gui
start
to work?

Run it in a command prompt and *post the error message*, then we can 
help. There is a sample called ''minimal.rb'' in the
distribution that you
can use as a basis for testing and the starting point for your own apps.

a

Piture is error message. This is testing of my application.
