Dear Jan Möbius, Thanks for your helpful answers. Concerning to topic: About the plugin desing : one host and other slaved.
We still have our different view. Firstly, We do not want to put the host class and the slave classes into different folders, instead, we prefer to keeping them together in the same project, because they focus on the same 'business'. We split them because we want to make the 'business' looks clear; We make them inherit by LogInterface, RPCInterface and others because we need to call external functions, like log, rpc, within them.
Secondly, let me state the problems with our current design. For example, we have a subclass named :GeometricSignature.cpp. We put Q_EXPORT_PLUGIN2( lmgcgeometricsignature , LMGCGeometricSignature); at the bottom of it. however, we got the following building eorrs 2>Linking... 2>LMGCPlugin.obj : error LNK2005: _qt_plugin_query_verification_data already defined in GeometricSignature.obj 2>LMGCPlugin.obj : error LNK2005: _qt_plugin_instance already defined in GeometricSignature.obj
if we remvoved Q_EXPORT_PLUGIN2( lmgcgeometricsignature , LMGCGeometricSignature); out of it, Building is fine, but calls to those external functions do not work; that is say, no errors, no feedbacks; From the log window, we can see only the main class is loaded; other subclasses do not loaded as plugins even they have the same inheritance as the main class.
We are looking forward to hearing suggestions from you. Best Regards,

Dear Openflipper developer,
We saw that, in openflipper, the initial Guassian curvature for each vetex is : double gauss_curv( 2.0*M_PI); However, in lots of papers, they set the initial value to M_PI, if it is a boundary vertex.
Could you please explain such difference? Thank you for your great work in graphics community!

Dear Openflipper developer, Suppose we have built up a plugin, but we want to split it into a classes and other slaved ones. Every inherits from QObject, BaseInterface, LoggingInterface, StatusbarInterface, RPCInterface such that they can call other plugin functions, like log, rpc::callFunction, by themselves.
The problem is that we found such design does not work, because they can not work as we imagine; Only the primary one works fine.
Therefore, we want to ask for suggestions for the support team!

This setup is fine. Usually we also split the functionality into basic plugins. You have to put the plugins into separate folders at OpenFlippers top level directory. Additionally you have to make sure, that they have different names (especially the plugin name returned has to be different).
You can only have one class handling the interfaces in your plugin. All other classes can be derived from QObject but have to communicate to the core via the main plugin class (But you can connect the signals of your subclass directly to the signals of your ain class).
The problem is that we found such design does not work, because they can not work as we imagine;
Do you get any error message?
Only the primary one works fine.
Take a look at the log window. When OpenFlipper starts, it shows which plugins get loaded in the log window. Check for messages regarding plugins that are not loaded. If you use linux, you can start OpenFlipper with the command line option "-c" which will print the full log to your console.
Best, Jan Möbius
