static

Recalculates the star pixmaps.

Definition at line 263 of file skyqpainter.cpp.

◆ releaseImageCache()

static

Release the image cache.

Definition at line 96 of file skyqpainter.cpp.

◆ setBrush()

void SkyQPainter::setBrush ( const QBrush & brush)
overridevirtual

Set the brush of the painter.

Implements SkyPainter.
