Hi everyone,
I'm looking for information on marble layer management:

• can I define the transparency of a definitive layer in the DGML?
• can I show / hide layers at runtime?
• where can I find the specification of the DGML format?
• why isn't the GeoSceneDocument.h and other headers available in the include folder? How can I get to use the GeoSceneMap object which has the method:
  QVector <GeoSceneLayer *> layers () const;

Thanks in advance,
Paolo

Although I have not used DGML extensively, I believe layer visibility should be possible by simply removing/adding said layer.
To change the visibility of a specific GeoDataFeature, there is a setVisible function, and an updateFeature function. (Will post links when the KDS API site is back up).
Be warned, I have encountered issues using this with GeoDataGroundOverlays (incorrect layers' visibility being toggled, crashes).
I posted a question here (viewtopic.php?f=217&t=168009&sid=ba682dd9b834558a87f914ce1b4b51a5#p437792), and will probably submit an issue.

See https://api.kde.org/marble/html/classMa ... Model.html for addDocument/removeDocument and updateFeature.
See https://api.kde.org/marble/html/classMa ... ature.html (https://api.kde.org/marble/html/classMa ... 227c7d9143) for setVisible.
