Hi,<div><br></div><div>Im using marble lib from the svn, latest revision, and I would like to know about the placemarks.</div><div>I want to set Placemarks on the marble widget with the names of points in a route (programatically), like the runners example in the techbase to mark a point somewhere with a label and a dot.</div>
<div>I have viewed the marble code and the techbase runners Example to get some clues, and I wrote the next code:</div><div><br></div><div><meta name="qrichtext" content="1"><style type="text/css">
p, li { white-space: pre-wrap; }
</style>

After the application's window lost focus (i launch a calculator or show the yakuake window), the program crashes.This make me think about an update in the marble widget and the inserted placemarks making some unexpected thing together.</font></span></pre>
<div><br></div>Maybe im not using the right class (GeoDataPlacemark). I have seen on the documentation the classes VisiblePlacemark, PlacemarkLayout, and PlacemarkPainter, but i could not find how to use them.</div><div><br>
</div><div>I also tried to use marbleWidget's addPlacemarkFile() method (and did further tests with marble -the application- opening a kml file) with sample <a href="http://code.google.com/apis/kml/documentation/kml_tut.html#placemarks">xml</a> from google kml documentation, but nothing is rendered on the map (i think the placemarks are not visible or not drawn, just added invisible placemarks -like bookmarks-). I noted that if i placed placemarks with a <a href="http://code.google.com/apis/kml/documentation/kml_tut.html#paths">path</a> the path is drawn on the map (with the addPlacemarkFile() method), which makes me think that drawing <a href="http://code.google.com/apis/kml/documentation/kml_tut.html#placemarks">Placemarks</a> is not implemented in marble when loading placemarks from kml files. </div>
<div><br></div><div>I also found PlacemarkTextAnnotation class, and the osmannotate plugin but this is not compiled (commented on the CMakeLists.txt). Is it not finished?</div><div><br></div><div>I found a <a href="http://www.youtube.com/watch?v=hTKc546-gjQ">video</a> that shows annotations, a feature near to what i want... but that seems to be old (1 year) and not present on the marble source code. And a blog post about adding <a href="http://techespanto.wordpress.com/2010/05/05/gsoc-10-proposal-adding-bookmark-and-annotation-feature-in-kde-marble/">annotations for a GSOC project</a> (some months ago).</div>
<div><br></div><div>Well, any help will be appreciated. </div><div>Thanks.</div><div><br>-- <br>Miguel Chavez Gamboa<br><br>
