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 cAbstractImageFigure.

◆ dup()

virtual cImageFigure* 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 cAbstractImageFigure.

Reimplemented in cIconFigure.

◆ str()

virtual std::string str ( ) const
overridevirtual

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

Reimplemented from cFigure.

◆ 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 cAbstractImageFigure.

◆ 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.

Reimplemented in cIconFigure.

◆ getImageName()

virtual const char* getImageName ( ) const
inlinevirtual

Returns the string that identifies the image to display.

◆ setImageName()

virtual void setImageName ( const char *  imageName)
virtual

Sets the image to display. The imageName parameter must identify an image loaded from the OMNeT++ image path, in the form also used by the display string "i" tag: with subdirectory names but without filename extension. Examples: "block/queue" or "device/switch_vl".

◆ getImageNaturalWidth()

virtual int getImageNaturalWidth ( ) const
inlinevirtual

Returns the "natural" width of the image. For raster images, this is the width of the image in pixels.

Caveat: when the simulation is running under Cmdenv or another non-GUI environment, the returned width may be a guess or a made-up number, as Cmdenv does not actually load the images files.

See also
cAbstractImageFigure::getBounds(), cEnvir::getImageSize()

◆ getImageNaturalHeight()

virtual int getImageNaturalHeight ( ) const
inlinevirtual

Returns the "natural" height of the image. For raster images, this is the height of the image in pixels.

Caveat: when the simulation is running under Cmdenv or another non-GUI environment, the returned height may be a guess or a made-up number, as Cmdenv does not actually load the images files.
