Member Function Documentation

void StelSkyImageTile::draw ( StelCore core,
const StelPainter sPainter 

Draw the image on the screen.

DataSetCredits StelSkyImageTile::getDataSetCredits (  )  const [inline]

Return the dataset credits to use in the progress bar.

ServerCredits StelSkyImageTile::getServerCredits (  )  const [inline]

Return the server credits to use in the progress bar.

bool StelSkyImageTile::isReadyToDisplay (  )  const

Return true if the tile is fully loaded and can be displayed.

QVariantMap StelSkyImageTile::toQVariantMap (  )  const

Return the absolute path/URL to the image file.

virtual void StelSkyImageTile::loadFromQVariantMap ( const QVariantMap &  map  )  [protected, virtual]

Load the tile from a valid QVariantMap.

Implements MultiLevelJsonBase.
