cPieSliceFigure Class Reference

#include <ccanvas.h>

Description

A figure that displays a pie slice, that is, a section of an axis-aligned disc or filled ellipse.

A pie slice is determined by the bounding box of the full disc or ellipse, and a start and an end angle. The outline of the pie slice in non-degenerate cases consists of an arc, and two straight lines from the center of the pie to the end points of the arc.

For the start and end angles, zero points east, and angles are measured in the counter-clockwise direction. Values outside the (0,2*PI) interval are accepted for both angles.

As with all shape figures, drawing of both the outline and the fill are optional. Line and fill color, and several other properties are inherited from cAbstractShapeFigure.

The pie slice is drawn from the start angle to the end angle in counter- clockwise direction. In non-degenerate cases, the end angle should be in the (startAngle, startAngle + 2*PI) interval. If the end angle equals to or is less than the start angle, only a straight line is drawn from the center to the circumference. If the end angle equals startAngle+2*PI or is greater than that, a full circle or ellipse, and a straight line from the center to the circumference at angle endAngle is drawn.

Member Function Documentation

◆ getAllowedPropertyKeys()

virtual const char** getAllowedPropertyKeys ( ) const
overrideprotectedvirtual

Returns the list of allowed keys in @figure properties with this figure type, in a nullptr-terminated array of const char* elements. This method is invoked e.g. from parse(), in order to be able to issue error messages for invalid keys in the property. Note that property keys starting with "x-" are already allowed by default. Custom figure classes usually need to override this method together with parse(); see the source code of the library classes for example implementations.

Reimplemented from cAbstractShapeFigure.

◆ dup()

virtual cPieSliceFigure* dup ( ) const
inlineoverridevirtual

Clones the figure, ignoring its child figures. (The copy will have no children.) To clone a figure together with its figure subtree, use dupTree().

Reimplemented from cAbstractShapeFigure.

◆ str()

virtual std::string str ( ) const
overridevirtual

Returns a one-line string with the most characteristic data of the figure.

Reimplemented from cAbstractShapeFigure.

◆ parse()

virtual void parse ( cProperty property)
overridevirtual

This method is invoked by the simulation library to initialize the figure from a @figure NED property. Custom figure classes usually need to override this method (and call the super class' similar method in it).

Note: When overriding parse(), it is usually also necessary to override getAllowedPropertyKeys(), in order to allow new keys in the @figure property.

Reimplemented from cAbstractShapeFigure.

◆ moveLocal()

virtual void moveLocal ( double  dx,
double  dy 
)
overridevirtual

Change the figure's position by the given x and y deltas. Child figures will not be affected.

Implements cFigure.

◆ getRendererClassName()

virtual const char* getRendererClassName ( ) const
inlineoverridevirtual

Returns the name of the class responsible for rendering this figure. Renderer classes are specific to, and are usually implemented as part of, the graphical user interface library e.g. Qtenv.

Implements cFigure.

◆ getBounds()

virtual const Rectangle& getBounds ( ) const
inlinevirtual

Returns the bounding box of the axis-aligned circle or ellipse the pie slice is part of.

◆ setBounds()

virtual void setBounds ( const Rectangle bounds)
virtual

Sets the bounding box of the axis-aligned circle or ellipse the pie slice is part of.

◆ setPosition()

virtual void setPosition ( const Point position,
Anchor  anchor 
)
virtual

Utility function. Moves the bounding box so that its point denoted by anchor will be at the given position.

◆ getStartAngle()

virtual double getStartAngle ( ) const
inlinevirtual

Returns the start angle of the pie slice in radians. See the class documentation for details on how the pie slice is drawn.

◆ setStartAngle()

virtual void setStartAngle ( double  startAngle)
virtual

Sets the start angle of the pie slice in radians. See the class documentation for details on how the pie slice is drawn.

◆ getEndAngle()

virtual double getEndAngle ( ) const
inlinevirtual

Returns the end angle of the pie slice in radians. See the class documentation for details on how the pie slice is drawn.

◆ setEndAngle()

virtual void setEndAngle ( double  endAngle)
virtual

Sets the end angle of the pie slice in radians. See the class documentation for details on how the pie slice is drawn.
