news 28 Posted May 25, 2010 Hello everyone, libchamplain 0.6 is out. There hasn't been much exciting since 0.5.2; here's a brief list of changes: * Add dummy ChangeLog file (Ã…Âukasz Jernaś) * Fix a problem on some machines when tiles are being destroyed (JiřàTechet) * Add minimal demos (JiřàTechet) * Some other minor fixes (JiřàTechet) For more details refer to git log. This is probably the right place to point out several incompatibilities with the 0.4 branch. There have been many changes in the API so it's possible you encounter some errors while compiling your program, but these should be easy to fix. However, there are two gotchas if you are upgrading from the previous stable release mainly because your sources will compile just fine, but when running it, unexpected things happen: 1. ChamplainMapSource and ChamplainPolygon inherit from GInitiallyUnowned now and g_object_ref_sink() is called on them. The practical consequence is that you MUST NOT call g_object_unref() once you insert them to ChamplainView, otherwise your application will crash. libchamplain takes ownership of them so you don't have to care about their deallocation any more. 2. If you want to create a cached map source, call champlain_map_source_factory_create_cached_source() instead of champlain_map_source_factory_create(). The latter function will just create the bare map source without any caching. So if it seems to you the tiles don't get cached, this is probably the cause. We're late with this release but I'll do my best to follow the gnome schedule for the following release. In a few days I'll send a few ideas what I'd like to have implemented for 0.8. Cheers, Jiri _______________________________________________ Share this post Link to post
