[Qgis-developer] Basic question: How to select a layer in the GUI and get the handle in the Python code?

[Ole Nielsen]

Thanks for your help. Using QgsVectorLayer worked straight away to give the
handle from the source files.
I assume OgsRasterLayer will work the same way. I can use the file name
extension to determine if the file is raster or vector but was wondering if
Qgis has a library for that too?

Cheers and thanks
Ole
