class QgsQueryBuilder : QDialog
{
%Docstring
 Query Builder for layers.

 The query builder allows interactive creation of a SQL for limiting the
 features displayed in a vector layer.  The fields in the table are
 displayed and sample values (or all values) can be viewed to aid in
 constructing the query. A test function returns the number of features that
 will be returned.

 Test the constructed sql statement to see if the vector layer data provider likes it.
 The number of rows that would be returned is displayed in a message box.
 The test uses a "select count(*) from ..." query to test the SQL
 statement.

 are inserted into the values list box.
