Qyoto is a set of bindings created by the KDEbindings team that wrap the Qt framework. Although it provides much more, Qt is mostly known as a professional cross-platform GUI toolkit. It is used by 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.

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.

On Linux, sources for Qyoto are generated by a 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 download page.

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:

uics.exe -o yourproject.ui.cs yourproject.ui
csrcc.exe -o yourproject.qrc.cs yourproject.qrc

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:

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(); 
        }
    }
