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.

%Docstring
This constructor is used when the query builder is called from the
vector layer properties dialog

%Docstring
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.
