/**

|
|
*
|
|
* @short A KConfigSkeleton that populates itself based on KConfigXT XML
|
|
*
|
|
* This class allows one to ship an XML file and reconstitute it into a
|
|
* KConfigSkeleton object at runtime. Common usage might look like this:
|
|
*
|
|
* \code
|
|
* QFile file(xmlFilePath);
|
|
* Plasma::ConfigLoader appletConfig(configFilePath, &file);
|
|
* \endcode
|
|
*
|
|
* Alternatively, any QIODevice may be used in place of QFile in the
|
|
* example above.
|
|
*
|
|
* Currently the following data types are supported:
|
|
*
|
|
* @li bools
|
|
* @li colors
|
|
* @li datetimes
|
|
* @li enumerations
|
|
* @li fonts
|
|
* @li ints
|
|
* @li passwords
|
|
* @li paths
|
|
* @li strings
|
|
* @li stringlists
|
|
* @li uints
|
|
* @li urls
|
|
* @li doubles
|
|
* @li int lists
|
|
* @li longlongs
|
|
* @li path lists
|
|
* @li points
|
|
* @li rects
|
|
* @li sizes
|
|
* @li ulonglongs
|
|
* @li url lists
