[Marble-devel] Help with MarbleWidget

[Bryan Greenway]

Thanks to Torsten and Sylvain for your responses.  I figured out the
issue...a very silly one (I'm embarrassed to say). 

There was a problem with the given path in my .pro file (shown here): LIBS
+= -L"c:\marble-build\src\lib\" "libmarblewidget.dll" 

The last '\' in the path was causing the problem.  Once removed, it all
worked like a charm.

I now have a simple dialog app running with the MarbleWidget on it, all done
inside Qt Creator on Windows-Vista. Very cool.

Now I'm moving on to try to get the behavior I need.  I'm still very low on
the Marble learning curve, but once I get the basic functionality of the app
going, I'll gladly share the code with anyone that wants to see how I used
this excellent Widget in a simple app and using Qt Creator.

Current issues:

1 - the map seems to be using the data cache and not going out on the net to
get new data (i.e. working offline).

2 - drawing a moving "placemark" on the map that represents the current
location of a vehicle feeding me it's GPS coordinates.

I'll be working on these today.

Sorry for all the questions...just getting excited about the power that
Marble has put in my hands.

Bryan

Hi Bryan,

Sorry, so far I haven't managed to write up the Tutorial I promised earlier.
:-(

Currently the only other way to add placemarks is through:

void MarbleWidget::addPlacemarkFile( const QString &filename );
void MarbleWidget::addPlacemarkData( const QString& data, const QString& key
= 
"data" );

The file or string has got to be formatted as a KML file:

This is quite convenient but the results are currently rather "fixed". 

So instead you might want to draw your own placemarks using the GeoPainter's

Annotations for example.

I don't see a problem with these. Looks all fine to me (but I don't have any

experience with compiling Marble on Windows, so ...).

They are part of the library and they should get included from the
ControlView 
IIRC. You can of course include the headers of those files but it doesn't
look 
like a header problem to me - rather some problem with linking. 

Best Regards,

Torsten
