/** Advanced search history.
|
|
*
|
|
* We store previous searches using the "dynconf" mechanism, as string
|
|
* entries under the "advSearchHist" key. The strings are generated by
|
|
* translating the SearchData structure to XML, which is done by
|
|
* calling SearchData::asXML().
|
|
* When reading, we use a QXmlSimpleReader and QXmlDefaultHandler to
|
|
* turn the XML back into a SearchData object, which is then passed to
|
|
* the advanced search object fromSearch() method to rebuild the
|
|
* window state.
|
|
*
|
|
* XML generation is performed by ../rcldb/searchdataxml.cpp.
|
|
* See xmltosd.h for a schema description
