Constructor & Destructor Documentation

GraphicsContext() [1/2]

GraphicsContext::GraphicsContext ( wxPaintDC &  dc, const Rgba  color  )

inline

Constructs the drawing context from wxPaintDC.

Definition at line 69 of file GraphicsContext.h.

GraphicsContext() [2/2]

GraphicsContext::GraphicsContext ( wxMemoryDC &  dc, const Rgba  color  )

inline

Constructs the drawing context from wxMemoryDC.

Definition at line 77 of file GraphicsContext.h.

Member Function Documentation

drawErrorPoint()

virtual void GraphicsContext::drawErrorPoint ( const ErrorPlotPoint &  point )

inlineoverridevirtual

Adds a point with error bars to the plot.

Implements IDrawingContext.

Definition at line 90 of file GraphicsContext.h.

drawLine()

virtual void GraphicsContext::drawLine ( const PlotPoint &  from, const PlotPoint &  to  )

inlineoverridevirtual

Draws a line connecting two points.

The ending points are not drawn; call drawPoint manually if you wish to draw both lines and the points.

Implements IDrawingContext.

Definition at line 94 of file GraphicsContext.h.

drawPath()

virtual AutoPtr<IDrawPath> GraphicsContext::drawPath ( )

inlineoverridevirtual

Draws a path connecting points.

The path copies the state from the parent drawing context, so if a drawing style of the context changes, the change does not affect already existing paths.

Implements IDrawingContext.

Definition at line 102 of file GraphicsContext.h.

drawPoint()

virtual void GraphicsContext::drawPoint ( const PlotPoint &  point )

inlineoverridevirtual

Adds a single point to the plot.

The plot is drawn by implementation-defined style.

Implements IDrawingContext.

Definition at line 84 of file GraphicsContext.h.

setStyle()

virtual void GraphicsContext::setStyle ( const Size  index )

inlineoverridevirtual

Changes the current drawing style.

Interpretation of the style is implementation-defined. It is assumed that the derived classes will have a predefined set of drawing styles, this function will then selects the style with appropriate index.

Parameters

index

Index of the selected style.

Implements IDrawingContext.

Definition at line 106 of file GraphicsContext.h.

setTransformMatrix()

virtual void GraphicsContext::setTransformMatrix ( const AffineMatrix2 &  matrix )

inlineoverridevirtual

Applies the given tranformation matrix on all primitives.

This does not affect already drawn primitives.

Implements IDrawingContext.

Definition at line 120 of file GraphicsContext.h.
