Federico Mena Quintero	23d1d18619	Convert stringified timestamps from D-Bus to integers We already had the symmetrical code to convert numerical timestamps to strings before sending out D-Bus requests, anyway. Signed-off-by: Federico Mena Quintero <federico@gnome.org>	2011-03-31 13:07:44 -04:00

Seif Lotfy	fb5a3a53fa	Don't refresh all the search providers in O(n^2) fashion; just refresh the one that changed This modification reduces the faulty clearing and redrawing of the results. The old code refreshed the view for every async search provider by iterating through all result sets (one result set per provider) and refreshing all providers. In this case there were 40 redraws. This patch adds a new method _clearDisplayForProvider that allows us to refresh only providers with changed results.	2011-03-04 16:42:15 -05:00
Federico Mena Quintero	30eac56691	Merge master into zeitgeist	2011-03-03 21:51:15 -05:00
Federico Mena Quintero	cb6f3a0836	Add all of Zeitgeist's enum values for ResultType and StorageState These are copied from the Python code. It's unfortunate that we can't introspect enum values from D-Bus. Signed-off-by: Federico Mena Quintero <federico@gnome.org>	2011-03-03 21:40:44 -05:00
