[Qgis-developer] question about location of providerregistry and pluginregistry

[Marco Hugentobler]

Hi,

In svn head, qgsproviderregistry.h is in core/ directory and 
qgspluginregistry.h in app/ directory. I wanted to ask what the reason for 
this is.
Backgournd of my question is that I'm trying to restore the diagram overlay 
from project file. For this, QgsVectorLayer needs to have a pointer to the 
diagram plugin (in case it is loaded). From a pure technical point of view 
this is similar to QgsVectorLayer using QgsProviderRegistry to restore a data 
provider from project file. But because plugin registry is in app, vector 
layer is not allowed to use it, as code in core should not depend on code in 
app.
Is it possible that QgsPluginRegistry could be in core? Or is there a more 
intelligent way of getting the plugin pointer?

Thanks,
Marco
