   GUI plugin development
  I am looking to create a plugin architecture that works similarly to Eclipse, I think I understand how to create the plugin hierarchy however I am unsure of how to do the GUI in C++.I was thinking of using the FOX-toolkit or WXWidgets as the actual GUI toolkit however I want it to be one level abstracted (ie: plugins that wish to modify the gui make calls like: Create_Window(p_WindowID, content_Struct) rather than specific fox or Wx calls). However I am not sure quite how to do this in practice,googling turns up a lot of gui plugin links related to specific projects but nothing thats purely theoretical or layered that I can see. The closest I have come is the freeride project (A ruby project). So really my question is does anyone have any examples or references to this sort of project?Thanks   
  Hmmm, maybe try taking a look at how Guichan has achieved its library independance, ie. http://guichan.sourceforge.net/api/classgcn_1_1Graphics.html.Basically, standard class inheritance + polymorphism: you write a base abstract class (interface) which declares some methods, then you inherit from that class and implement those methods. In main program you declare pointer to base class, and use only it - no specific calls to API. Obviously, this pointer may point to WxWidgets plugin or FOX-Toolkit plugin etc. just new it up (in C++) on the begginning.However, comning up with one interface that suits all intended libraries may be hard. Good luck! :-)   ;  Hard is good, have to have a reasonable level of difficulty for this and a pile of research / new techniques for my project. Thanks for the link, finding examples of this sort of stuff is hard, just finding the right keywords to narrow the search in google can be difficult.
