QMapControl

[rage]

I am developing a mapping widget for Qtopia (also running under Qt). This widget allows you to add maps into your applications. The maps can be loaded from WMS servers or (my favourite) from the OpenStreetMap project. Then you can add your custom data into the maps. You can add Points, Lines, etc. to specific coordinates. Also you can display other widgets on coordinates.

For further information please visit the project website: http://medieninf.de/qmapcontrol

This is VERY interesting.
We will need such a widget in our project, and I was afraid we will have to implement it ourselves (time problems!)
So, in the following months we will try it, and you will probably hear from us :-)

I just tried the win32 version, and it says that it can't find (linker scrambled): "qt_message_output9QtMsgTypePKc" in QtCore4.Dll".
I put the dll at the same folder as the exe, it it should not be a case of a missing dll. (Qt4.3.2)

I've compiled it with Qt 4.3.1. I don't know if this might be a problem. I uploaded my DLLs, maybe this works.

yes it works with the binaries you supplied...

Hi,

I need to display raster maps in my application, i am using Qt 4.2.2.
can i directly use the API's provided in this site mentioned above.
Can you suggest how to use the APIs to display any raster map on a normal Qt widget?

Looking forward to your response

I've replied to your mail.

Its a very interesting proyect! It is like the Google Maps Lib but for applications!
Rage, does the programm tells shortes-path from point to point, or do some kind of path-finding? It could be an excellent idea also (More difficult) if the programm can search for different sort of transports so you can see wether if you can go via bus to some point.

Hmm, that could be possible, if somebody implements it... The widget is a good base to develop such an application. To calculate routes for instance, webservices from openstreetmap can be used. Their API provides to get "geometry information" and therewith a possibility to calculate routes....
The widget as is just displays map tiles and additional things like lines, points, images, other widgets...

Hi,
I would need to use such a nice widget with raster or vector files in an offline application. Is it possible ? Any help is welcome.

Thx,
Cedric.

Currently it is only possible to display pre-rendered map tiles from map providers like OpenStreetMap. QMapControl allows to cache tiles persistently but this might not be the best solution for you.
It should be possible to display vector graphics whose underlying data could be stored local. But I have not planned to implement this feature. Maybe someone else is willing to do this.
