Qt Location, Map Cache

[deleted286]

Is there any example of mapping cache? I want to do, disk cache . I couldnt find any example related to this topic exactly

@suslucoder
on what platform?
On linux you can set XDG_CACHE_HOME and XDG_DATA_HOME environment variables. Which are actually interpreted by QStandardPaths::CacheLocation
And IIRC it is used by QtLocation to write the map cache.

@raven-worx is it possible on windows?

@suslucoder
on windows there doesn't seem to be a generic way.

About what map provider plugin are we talking here actually?
The here plugin provides an extra parameter to do what you want for example. Whereas the osm plugin doesn't.

@raven-worx actually im searching a way to, run my map wihtout any ethernet connection. I think that cache a disk is a way for it
