I'm part of this people. hbQt could be the best choice due to his multiplatform, rich and well documented implementation, but the approach is very critical whan applied to existing Clipper code. > > > This is the main problem of > > every GUI library.

You are right. I agree with the "compatibility layer" as I used something similar to wrap hwGUI objects to my Clipper framework and worked fine. But I ask you for a reference to the thread about the XBP inconsistency in this approach, or a summary of your thought about. I'm very interested in use xBase Parts and, because I yet made a compatibility layer for xBase++, I would know what part of the layer could be critical in this approach whit Harbour. TIA.
