Graphical integration of WPF/WinForms into Java

Windows Forms and WPF User Interface Integration

The Java AWT window with the WPF (Top left area) and the WinForms (Top right area) controls integrated .

In this little more complex example we integrate into an awt java user interface two different complex control, taken from two .NET library. The first control is a Windows Form, the second one is a WPF object. The application in \JVM\Java\src\AWTWinFormsWPF.java expose the complete process from the control reference and generation to the .NET event listener registration to the .NET events callback management.
