I'm trying to create a simple application, written in Ruby via Qt. I designed a form (MainForm) in a Qt Designer and translated it via rbuic4 to the Ruby code representation. The pure untouched result has four methods, and looks like this:

=begin
** Form generated from reading ui file 'stackover.ui'
**
** Created: Р’С‚ 24. РЅРѕСЏ 21:15:02 2009
**      by: Qt User Interface Compiler version 4.3.1
**
** WARNING! All changes made in this file will be lost when recompiling ui file!
=end

class Ui_MainWindow
    attr_reader :centralwidget
    attr_reader :pushButton
    attr_reader :listView
    attr_reader :menubar
    attr_reader :statusbar

    def setupUi(mainWindow)
    mainWindow.setObjectName("mainWindow")
    @centralwidget = Qt::Widget.new(mainWindow)
    @centralwidget.setObjectName("centralwidget")
    @pushButton = Qt::PushButton.new(@centralwidget)
    @pushButton.setObjectName("pushButton")
    @pushButton.setGeometry(Qt::Rect.new(10, 10, 75, 23))
    @listView = Qt::ListView.new(@centralwidget)
    @listView.setObjectName("listView")
    @listView.setGeometry(Qt::Rect.new(10, 40, 431, 192))
    mainWindow.setCentralWidget(@centralwidget)
    @menubar = Qt::MenuBar.new(mainWindow)
    @menubar.setObjectName("menubar")
    @menubar.setGeometry(Qt::Rect.new(0, 0, 451, 21))
    mainWindow.setMenuBar(@menubar)
    @statusbar = Qt::StatusBar.new(mainWindow)
    @statusbar.setObjectName("statusbar")
    mainWindow.setStatusBar(@statusbar)

    retranslateUi(mainWindow)

    size = Qt::Size.new(451, 276)
    size = size.expandedTo(mainWindow.minimumSizeHint())
    mainWindow.resize(size)


    Qt::MetaObject.connectSlotsByName(mainWindow)
    end # setupUi

    def setup_ui(mainWindow)
        setupUi(mainWindow)
    end

    def retranslateUi(mainWindow)
    mainWindow.setWindowTitle(Qt::Application.translate("MainWindow", "MainWindow", nil, Qt::Application::UnicodeUTF8))
    @pushButton.setText(Qt::Application.translate("MainWindow", "PushButton", nil, Qt::Application::UnicodeUTF8))
    end # retranslateUi

    def retranslate_ui(mainWindow)
        retranslateUi(mainWindow)
    end

end

module Ui
    class MainWindow < Ui_MainWindow
    end
end  # module Ui

The major idea is to create a Ruby-Qt application, to run my small Ruby apps with GUI - as for now I don't need all the power of Qt library.

I'm aware of this great example, but it shows off a different generated code for the .ui file. Or did they managed to alter it somehow? Anyway, their example works fine, while I can't make my own working properly.

I just don't know what to do with my generated file, how to go further and make a connection with my Ruby program... Maybe my rbuic4 is wrong? Or am I'm running it with incorrect options (I'm an -o option) to get the arachnoid-like template?

A: 

Well, Ok. As far as I cannot find the exact use of the mentioned generated file, I decided to copy-paste component init. code to another Ruby-Qt template app, where's everything is clear for me. Thus QtDesigner and rbui4 are only useful for quick form design/translation, which should be then followed by all required manual polishing.

Waiting for newer version of rbuic4 and QtRuby support of urgent version of Qt.

The easiest way to actually DO something with your code is to regenerate it like this:

rbuic4 -x stackover.ui -o stackover.ui.rb

Than sun the generated stackover.ui.rb file like this:

ruby stackover.ui.rb

Hope it helps.
