Qt Mobility Tech Preview - Maps and Navigation API

danilocesar

Is it tile based or OviMaps based?

dalaing

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

dalaing

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 ?

dalaing

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 ?

iksaif

Yes, you just need to build QtMobility for windows and it will work like it does on Linux.
