In the meantime.. - rendering the waypoint flag now works - toolbar buttons now work - zoom slider now works - autocenter fixed and gconf-ed It's already shaping up quite nicely :) > > Some things I noticed : > > > > It seems the tiles-queued signal is only triggered when downloading tiles > > 'on-demand', > > i.e. when dragging the map around.

If I recall correctly, tangogps used 2 queues for downloading tiles, a low priority one for the bulk map-download, and a high priority one for the on-demand tiles. > > Also I triggered a 'bug', where I had a huge bbox en a high zoom level (I > > accidently used > > the old global_zoom variable instead of the internal zoom variable) when > > starting a map > > download.

Would cap the queue to 16384 for a perfectly square bounding box (still quite a lot), and it matches the max 7 zoom levels download of foxtrotgps. grtz, Sander _______________________________________________ This message is sent to you from [email protected] mailing list.
