[Qgis-developer] Writing a data provider in Python

[Barry Rowlingson]

I'm working with the 0.9 version and I've been writing python plugins 
happily. One thing I wanted to do was to be able to read excel 
spreadsheets into QGis.

I looked at the delimited text C++ plugin and so I understand the 
fundamentals of a vector data provider, but I can't see how to add a new 
one to the registry. It seems that the registry populates itself at 
startup time, and there's no 'add provider' method of QgsProviderRegistry.

So am I right in thinking that data providers have to be in C++ at the 
moment?

The workaround is to insist that my users export their excel 
spreadsheets as CSV files and then I use the very lovely delimited text 
plugin...
