Qt Mobility Tech Preview - Maps and Navigation API
-
The API is plugin based and will come with a Nokia / Ovi services based plugin which is platform independent.
-
super
-
Is it tile based or OviMaps based?
-
It's tile based and online only (from the Ovi tile based services) for the first release, and we hope to add support for vector based / offline mapping in the next release.
-
I believe the most great/killer feature of a maps API will be to access it offline...
And, afaik, nokia is the only "big player" capable of build it.
-
I agree. I'm looking forward to getting offline support working and seeing what the application developers do with it.
-
It seems that currently there is no control when to start/stop downloading online maps at qgraphicsgeomap
-
That's correct. The current plugin is for online maps - if you're viewing the map you're probably downloading map data (unless it's already been cached).
Do you have a use case for when someone might want to control the downloading for an online map viewer? Up until now I've been assuming that anyone using a map viewer with an online maps data plugin would be fine with handing control of when the downloading occurs to the viewer and/or the plugin.
There are some cache control hints you can give via parameters for the plugin - we'll document those properly once we sort out the naming and a few other issues.

What's the right way to add images on a map ? (like I do for "Lugdulo'V":http://xf.iksaif.net/dev/lugdulov.html, with qmapcontrol).
Should we use "QGeoMapObject":http://doc.qt.nokia.com/qtmobility-1.1-tp/qgeomapobject.html ) with the "Marker" type ? Then how can I set a pixmap ? Or maybe a new QGeoMapPixmap class comming ?
-
There is a QGeoMapPimapObject in the master branch of the git repository that will add images to a map.
Quite a few new classes are coming :)
-
Cool, that should fills my needs. Thanks !

Yes, offline access would be a killer feature. Are there any plans

Is it possible to create desktop application ( for windows7) using the maps API ?
I want to create one map application for windows7, which can show maps of variouse cities , calculate route, also I need to get exact co-ordinates for each point in the map.
is it possible using Qt maps api ? or is it like Qtmobility APIs will work only in devices ?
-
Yes, you just need to build QtMobility for windows and it will work like it does on Linux.
