Member Function Documentation

void SkyGLPainter::begin ( )

virtual

Begin painting.

Note

this function must be called before painting anything.

end()

Implements SkyPainter.

Definition at line 645 of file skyglpainter.cpp.

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

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

Implements SkyPainter.

Definition at line 276 of file skyglpainter.cpp.

void SkyGLPainter::drawFlags ( )

virtual

Draw flags.

Implements SkyPainter.

Definition at line 527 of file skyglpainter.cpp.

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

virtual

Implements SkyPainter.

Definition at line 432 of file skyglpainter.cpp.

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

virtual

Draw the symbols for the observing list.

Parameters

obs	the oberving list

Implements SkyPainter.

Definition at line 508 of file skyglpainter.cpp.

bool SkyGLPainter::drawPlanet ( KSPlanetBase *  planet )

virtual

Draw a planet.

Parameters

planet

the planet to draw

Returns

true if it was drawn

Implements SkyPainter.

Definition at line 232 of file skyglpainter.cpp.

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

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

Implements SkyPainter.

Definition at line 340 of file skyglpainter.cpp.

void SkyGLPainter::drawSatellite ( Satellite *  sat )

virtual

Draw a satellite.

Implements SkyPainter.

Definition at line 699 of file skyglpainter.cpp.

void SkyGLPainter::drawSkyBackground ( )

virtual

Draw the sky background.

Implements SkyPainter.

Definition at line 630 of file skyglpainter.cpp.

void SkyGLPainter::drawSkyLine ( SkyPoint *  a, SkyPoint *  b  )

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.

Implements SkyPainter.

Definition at line 602 of file skyglpainter.cpp.

void SkyGLPainter::drawSkyPolygon ( LineList *  list )

virtual

Draw a polygon in the sky.

Parameters

list	a list of points in the sky

See also

drawSkyPolyline()

Implements SkyPainter.

Definition at line 347 of file skyglpainter.cpp.

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

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.

Implements SkyPainter.

Definition at line 452 of file skyglpainter.cpp.

bool SkyGLPainter::drawSupernova ( Supernova *  sup )

virtual

Draw a Supernova.

Implements SkyPainter.

Definition at line 739 of file skyglpainter.cpp.

void SkyGLPainter::drawText	(	int	x,
		int	y,
		const QString	text,
		QFont	font,
		QColor	color
	)

Definition at line 563 of file skyglpainter.cpp.

void SkyGLPainter::end ( )

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

void SkyGLPainter::setBrush ( const QBrush &  brush )

virtual

Set the brush of the painter.

Implements SkyPainter.

Definition at line 675 of file skyglpainter.cpp.

void SkyGLPainter::setPen ( const QPen &  pen )

virtual
