===== What is Qyoto? ===== 
Qyoto is a set of bindings created by the [[http://techbase.kde.org/Development/Languages|KDEbindings]] team that wrap the [[http://trolltech.com/products/qt/|Qt framework]]. Although it provides much more, Qt is mostly known as a professional cross-platform GUI toolkit. It is used by [[wp>KDE]] to render their famous desktop and its open source edition is since version 4 also available for Windows. Using Qyoto, you can use this C++ framework in your .NET programs.

==== Qyoto on Linux ====
On Linux you can get Qyoto either from your distributions package manager, or from the KDE language bindings. You can also compile them yourself from the KDE subversion repository.

==== Qyoto on Windows ==== 
On Linux, sources for Qyoto are generated by a [[wp>Perl]] script from the installed Qt headers. This is a problem for Windows users, since Windows doesn't include Perl, like most Linux distributions do. Also the used scripts don't operate well in a Windows environment or on the slightly different Qt/Win edition.   In order to use Qyoto on Windows, you have to create the sources on Linux and the compile them in a Windows environment, see [[Building Qyoto for Windows]]. A binary package is available on our [[http://imaginary-project.net/download|download page]].   
 ===== Using Qyoto ===== 
To use Qyoto in your C# application, you need to add a reference qt-dotnet.dll. Next, you can use the Qt Designer, that comes with Qt, to visually design your GUI. When you save your design, you'll get one or two files: yourproject.ui containing the GUI data and yourproject.qrc containing the resources. Since you can't add them to your C# project directly, you'll need to convert them. You can use the command-line tools uics and csrcc for this:
<code>uics.exe -o yourproject.ui.cs yourproject.ui
csrcc.exe -o yourproject.qrc.cs yourproject.qrc</code>
 To do this automatically on every build, you can add these commands as pre-build event to your project. Now add the created .cs files to your C# project and start your window: 
 <code csharp>
class YourApp 
    {     // Test App  
        public static int Main(string[] args)  
        {
            QApplication app = new QApplication(args);
            QInitResources__dest_class__.QInitResources();
            QMainWindow mainwindow = new QMainWindow();
            Ui.MainWindow mainUi = new Ui.MainWindow();
            mainUi.SetupUi(mainwindow);
            mainwindow.Show();
            return QApplication.Exec(); 
        }
    }</code>
