Detailed Description

Extends QApplication to provide access to QGIS specific resources such as theme paths, database paths etc.

This is a subclass of QApplication and should be instantiated in place of QApplication. Most methods are static in keeping with the design of QApplication.

This class hides platform-specific path information and provides a portable way of referencing specific files and directories. Ideally, hard-coded paths should appear only here and not in other modules so that platform-conditional code is minimized and paths are easier to change due to centralization.
