◆ drawPointSource() [1/2]

void SkyQPainter::drawPointSource ( const QPointF pos,
float  size,
char  sp = 'A' 
)
virtual

This function exists so that we can draw other objects (e.g., planets) as point sources.

Definition at line 593 of file skyqpainter.cpp.

◆ drawPointSource() [2/2]

bool SkyQPainter::drawPointSource ( const SkyPoint loc,
float  mag,
char  sp = 'A' 
)
overridevirtual

Definition at line 151 of file skyqpainter.cpp.

◆ drawSkyLine()

void SkyQPainter::drawSkyLine ( SkyPoint a,
SkyPoint b 
)
overridevirtual

Draw a line between points in the sky.

Parameters
athe first point
bthe second point
Note
this function will skip lines not on screen and clip lines that are only partially visible.

Implements SkyPainter.

Definition at line 271 of file skyqpainter.cpp.

◆ drawSkyPolygon()

void SkyQPainter::drawSkyPolygon ( LineList list,
bool  forceClip = true 
)
overridevirtual

Draw a polygon in the sky.

Parameters
lista list of points in the sky
forceClipIf true (default), it enforces clipping of the polygon, otherwise, it draws the complete polygen without running any boundary checks.
See also
drawSkyPolyline()

Implements SkyPainter.

Definition at line 351 of file skyqpainter.cpp.

◆ drawSkyPolyline()

void SkyQPainter::drawSkyPolyline ( LineList list,

Parameters
lista list of points in the sky
skipLista SkipList object used to control skipping line segments
labela 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 297 of file skyqpainter.cpp.

◆ drawSupernova()

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

Implements SkyPainter.

Definition at line 146 of file skyqpainter.cpp.

◆ initStarImages()

void SkyQPainter::initStarImages ( )
static

◆ setPen()

void SkyQPainter::setPen ( const QPen pen)
overridevirtual

Set the pen of the painter.

Implements SkyPainter.

Definition at line 158 of file skyqpainter.cpp.

◆ setVectorStars()

void SkyQPainter::setVectorStars ( bool  vectorStars)
inline
Parameters
vectorStarsDraw stars as vector graphics whenever possible.
Note
Drawing stars as vectors is slower, but is better when saving .svg files. Set to true only when you are drawing on a canvas where speed doesn't matter. Definitely not when drawing on the SkyMap.
