Detailed Description

Reads and writes project states.

Note:

Has two general kinds of state to make persistent. (I.e., to read and write.) First, Qgis proprietary information. Second plug-in information.

A singleton since there shall only be one active project at a time; and provides canonical location for plug-ins and main app to find/set properties.

Might want to consider moving from Singleton; i.e., allowing more than one project. Just as the GIMP can have simultaneous multiple images, perhaps qgis can one day have simultaneous multiple projects.

void QgsProject::clearProperties ( )

syntactic sugar for property lists

extra properties, typically added by plug-ins

This allows for extra properties to be associated with projects. Think of it as a registry bound to a project.

Properties are arbitrary values keyed by a name and associated with a scope. The scope would presumably refer to your plug-in. E.g., "openmodeller".

Note:

E.g., open modeller might use:

"QgsProject::instance()->properties("openmodeller")["foo"].

Todo:: "properties" is, overall, a good name; but that might imply that the qgis specific state properites are different since they aren't accessible here. Actually, what if we make "qgis" yet another scope that stores its state in the properties list? E.g., QgsProject::instance()->properties()["qgis"]?

bool QgsProject::read ( QDomNode & layerNode )

read the layer described in the associated Dom node

Parameters:

layerNode represents a QgsProject Dom node that maps to a specific layer.

QgsProject raises an exception when one of the QgsProject::read() implementations fails. Since the read()s are invoked from qgisapp, then qgisapp handles the exception. It prompts the user for the new location of the data, if any. If there is a new location, the Dom node associated with the layer has its datasource tag corrected. Then that node is passed to this member function to be re-opened.
