[Gnumed-devel] re: "context" for gmMatchProvider

[syan tan]

in the test-area/sjtan modification of  
gmPhraseWheel.cSQL_MatchListProvider ,
I used the source_defs parameter to pass in an "extraConditions" 
function with
a "extraConditionsParam" (a list for numbered parameters)  to add  
additional selection clauses
e.g.
       extra_sql =   " and %s" %  source_defs['extraConditions']( 
*source_defs['extraConditionsParams'] )

and used it to join the _getNarrowings( for_table)  function in 
gmEditArea3 to gmPhraseWheel's match provider.

so that's one way of doing it.
