Description
A figure that displays an arc.
An arc's geometry is determined by the bounding box of the circle or ellipse the arc is part of, and the start and end angles. Other properties such as color and line style are inherited from cAbstractLineFigure.
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.
The arc is drawn from the start angle to the end angle in counter-clockwise direction. In non-edge cases, the end angle should be in the (startAngle, startAngle + 2*PI) interval. If the end angle equals or is less than the start angle, nothing is drawn. If the end angle equals startAngle+2*PI or is greater than that, a full circle is drawn.
Member Function Documentation
◆ getAllowedPropertyKeys()
|
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 cAbstractLineFigure.
◆ dup()
|
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 cAbstractLineFigure.
◆ str()
|
overridevirtual |
Returns a one-line string with the most characteristic data of the figure.
Reimplemented from cAbstractLineFigure.
◆ parse()
|
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 cAbstractLineFigure.
◆ moveLocal()
|
overridevirtual |
Change the figure's position by the given x and y deltas. Child figures will not be affected.
Implements cFigure.
◆ getRendererClassName()
|
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()
|
inlinevirtual |
Returns the bounding box of the axis-aligned circle or ellipse the arc is part of.
◆ setBounds()
|
virtual |
Sets the bounding box of the axis-aligned circle or ellipse the arc is part of.
◆ setPosition()
Utility function. Moves the bounding box so that its point denoted by anchor will be at the given position.
◆ getStartAngle()
|
inlinevirtual |
Returns the start angle of the arc in radians. See the class documentation for details on how the arc is drawn.
◆ setStartAngle()
|
virtual |
Sets the start angle of the arc in radians. See the class documentation for details on how the arc is drawn.
◆ getEndAngle()
|
inlinevirtual |
Returns the end angle of the arc in radians. See the class documentation for details on how the arc is drawn.
◆ setEndAngle()
|
virtual |
Sets the end angle of the arc in radians. See the class documentation for details on how the arc is drawn.
