I have completed the code for the implementation of the DesignSurface (The DesignSurface class implements what the user perceives as a designer. DesignSurface is the user interface the user manipulates to change design-time features. DesignSurface provides a completely self-contained design surface) and DesignSurfaceManager .Net 2.0 classes for the Mono class library. Currently it consists of 33 classes. I’ve started the testing phase by hosting Micro$oft’s Windows.Forms control’s designers. The final testing/compitability testing phase I have planned is to compile and test a copy of SharpDevelop 2 with my DesignSurface and related classes. I have also implemented the ComponentDesigner class and did a bit of the ControlDesigner class. I will make the source available once I have completed the testing/bugfixing/compitability improvements.
