Forum: wxRuby wxRuby + wxFormBuilder

Hello. I have a problems. Can you help me?

I create GUI-program, based on wxWidgets, in wxFormBuilder.

1.jpg) I create a form in wxFormBuilder, it will see as left part of
image. If i test it on View->XRC WIndow, it see as the right part of
1.jpg. What is it?

2.jpg) I generated code and start compilize it. But it failed. Why?

Thanks in advance

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?

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.

hth,

Hello Misha,

First off, welcome to wxRuby community.  I'll answer your other question 
in
a few, first we'll cover this one.

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

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.

Why everyone is silent?

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

bio.

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.

My friend talk me what was the problem. Now it's cloded. Thanks for your 
helps to me.
