Detailed Description

Draws things on the sky, without regard to backend.

This class serves as an interface to draw objects onto the sky without worrying about whether we are using a QPainter or OpenGL.

Member Function Documentation

virtual void SkyPainter::begin ( )

pure virtual

Begin painting.

Note

this function must be called before painting anything.

See also

end()

Implemented in SkyQPainter, and SkyGLPainter.

virtual bool SkyPainter::drawDeepSkyObject ( DeepSkyObject *  obj, bool  drawImage = false  )

pure virtual

Draw a deep sky object.

Parameters

obj	the object to draw
drawImage	if true, try to draw the image of the object

Returns

true if it was drawn

Implemented in SkyQPainter, and SkyGLPainter.

virtual void SkyPainter::drawFlags ( )

pure virtual

Draw flags.

Implemented in SkyQPainter, and SkyGLPainter.

virtual void SkyPainter::drawHorizon ( bool  filled, SkyPoint *  labelPoint = 0, bool *  drawLabel = 0  )

pure virtual

Implemented in SkyQPainter, and SkyGLPainter.

virtual void SkyPainter::drawObservingList ( const QList< SkyObject * > &  obs )

pure virtual

Draw the symbols for the observing list.

Parameters

obs	the oberving list

Implemented in SkyQPainter, and SkyGLPainter.

virtual bool SkyPainter::drawPlanet ( KSPlanetBase *  planet )

pure virtual

Draw a planet.

Parameters

planet

the planet to draw

Returns

true if it was drawn

Implemented in SkyQPainter, and SkyGLPainter.

virtual bool SkyPainter::drawPointSource ( SkyPoint *  loc, float  mag, char  sp = 'A'  )

pure virtual

Draw a point source (e.g., a star).

Parameters

loc	the location of the source in the sky
mag	the magnitude of the source
sp	the spectral class of the source

Returns

true if a source was drawn

Implemented in SkyQPainter, and SkyGLPainter.

virtual void SkyPainter::drawSatellite ( Satellite *  sat )

pure virtual

Draw a satellite.

Implemented in SkyQPainter, and SkyGLPainter.

virtual void SkyPainter::drawSkyBackground ( )

pure virtual

Draw the sky background.

Implemented in SkyQPainter, and SkyGLPainter.

virtual void SkyPainter::drawSkyLine ( SkyPoint *  a, SkyPoint *  b  )

pure virtual

Draw a line between points in the sky.

Parameters

a	the first point
b	the second point

Note

this function will skip lines not on screen and clip lines that are only partially visible.

Implemented in SkyQPainter, and SkyGLPainter.

virtual void SkyPainter::drawSkyPolygon ( LineList *  list )

pure virtual

Draw a polygon in the sky.

Parameters

list	a list of points in the sky

See also

drawSkyPolyline()

Implemented in SkyQPainter, and SkyGLPainter.

virtual void SkyPainter::drawSkyPolyline ( LineList *  list, SkipList *  skipList = 0, LineListLabel *  label = 0  )

pure virtual

Draw a polyline in the sky.

Parameters

list	a list of points in the sky
skipList	a SkipList object used to control skipping line segments
label	a pointer to the label for this line

Note

it's more efficient to use this than repeated calls to drawSkyLine(), because it avoids an extra points->size() -2 projections.

Implemented in SkyQPainter, and SkyGLPainter.

virtual bool SkyPainter::drawSupernova ( Supernova *  sup )

pure virtual

Draw a Supernova.

Implemented in SkyQPainter, and SkyGLPainter.

virtual void SkyPainter::end ( )

pure virtual

End and finalize painting.

Note

this function must be called after painting anything.

it is not guaranteed that anything will actually be drawn until end() is called.

See also

begin();

Implemented in SkyQPainter, and SkyGLPainter.

virtual void SkyPainter::setBrush ( const QBrush &  brush )

pure virtual

Set the brush of the painter.

Implemented in SkyQPainter, and SkyGLPainter.

virtual void SkyPainter::setPen ( const QPen &  pen )

pure virtual

Set the pen of the painter.

Implemented in SkyQPainter, and SkyGLPainter.
