Description

A lightweight graphical object for cCanvas.

This is the central class of OMNeT++'s 2D drawing API. Graphical elements are called figures, and are represented by subclasses of cFigure. To display a figure-based drawing, one needs to add figures to a canvas (cCanvas). Every module has its own canvas, accessible via cModule::getCanvas(), and one may also create additional ones.

Notes:

figures can be hierarchical (resulting in a figure tree)
coordinates are in canvas units, not in pixels (interactive zooming!)
coordinates are transformed with the figure's own transform plus the transforms of all ancestors
a figure subtree can be hidden by calling setVisible(false)
the order of child figures also denotes drawing order (of overlapping figures, the last one will appear on top)
dup() makes shallow copy (doesn't copy child figures); see dupTree() as well
figures are only data storage classes, rendering is done in the back-end (e.g. Qtenv) by separate renderer classes.

Member Function Documentation

◆ operator=()

cFigure& operator= ( const cFigure & other )

Assignment operator. It copies all data members except the object name, figure ID and child figures. (See cNamedObject::operator=() for details.)

◆ dup()

virtual cFigure* 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 cObject.

Reimplemented in cPixmapFigure, cIconFigure, cImageFigure, cAbstractImageFigure, cLabelFigure, cTextFigure, cAbstractTextFigure, cPathFigure, cPolygonFigure, cPieSliceFigure, cRingFigure, cOvalFigure, cRectangleFigure, cAbstractShapeFigure, cPolylineFigure, cArcFigure, cLineFigure, cAbstractLineFigure, cPanelFigure, and cGroupFigure.

◆ forEachChild()

virtual void forEachChild ( cVisitor * v )

overridevirtual

Calls v->visit(this) on each child figure. See cObject for more details.

Reimplemented from cObject.

◆ str()

virtual std::string str ( ) const

overridevirtual

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

Reimplemented from cObject.

Reimplemented in cPixmapFigure, cImageFigure, cAbstractTextFigure, cPathFigure, cPolygonFigure, cPieSliceFigure, cRingFigure, cOvalFigure, cRectangleFigure, cAbstractShapeFigure, cPolylineFigure, cArcFigure, cLineFigure, cAbstractLineFigure, cPanelFigure, and cGroupFigure.

◆ getId()

int getId ( ) const

inline

Returns the unique ID of this figure object. This ID is mostly intended for internal use.

◆ isVisible()

virtual bool isVisible ( ) const

inlinevirtual

Returns the visibility flag of the figure.

◆ setVisible()

virtual void setVisible ( bool visible )

virtual

Sets the visibility flag of the figure. Setting the visibility flag to false will cause the whole figure subtree to be omitted from rendering.

◆ getTransform()

virtual const Transform& getTransform ( ) const

inlinevirtual

Returns the transform associated with this figure.

◆ setTransform()

virtual void setTransform ( const Transform & transform )

virtual

Sets the transform associated with this figure. The transform will affect the rendering of this figure and its whole figure subtree. The transform may also be modified with the various translate(), scale(), rotate(), skewx()/skewy() methods.

◆ resetTransform()

virtual void resetTransform ( )

inlinevirtual

Convenience method: sets the transformation to identity transform.

◆ getZIndex()

virtual double getZIndex ( ) const

inlinevirtual

Returns the Z-index of the figure.

See also: getEffectiveZIndex()

◆ setZIndex()

virtual void setZIndex ( double zIndex )

virtual

Sets the Z-index of the figure. The Z-index affects the stacking order of figures via the effective Z-index. The effective Z-index is computed as the sum of the Z-indices of this figure and its ancestors'. A figure with a greater effective Z-index is always in front of an element with a lower effective Z-index. For figures with the same effective Z-index, their relative order in the preorder traversal of the figure hierarchy defines the stacking order. (A later figure is in front of the earlier ones.)

◆ getEffectiveZIndex()

virtual double getEffectiveZIndex ( ) const

virtual

Returns the effective Z-index of the figure. The effective Z-index is computed as the sum of the Z-indices of this figure and its ancestors'. A figure with a greater effective Z-index is always in front of an element with a lower effective Z-index.

◆ getTooltip()

virtual const char* getTooltip ( ) const

inlinevirtual

Returns the tooltip of the figure, or nullptr if it does not have one.

◆ setTooltip()

virtual void setTooltip ( const char * tooltip )

virtual

Sets the tooltip of the figure. Pass nullptr to clear the tooltip. If nullptr is set, the effective tooltip will be inherited from the associated object if there is one (see getAssociatedObject()), or from the parent figure. Empty tooltips will not be shown.

◆ getAssociatedObject()

virtual cObject* getAssociatedObject ( ) const

inlinevirtual

Returns the simulation object associated with this figure, or nullptr if it does not have one. The GUI may use this function to provide a shortcut access to the specified object, e.g. select the object in an inspector when the user clicks the figure.

◆ setAssociatedObject()

virtual void setAssociatedObject ( cObject * obj )

virtual

Sets the simulation object associated with this figure. The user is responsible for ensuring that the pointer is valid (the corresponding object exists), and remains valid while it is associated with the figure.

◆ getTags()

virtual const char* getTags ( ) const

inlinevirtual

Returns the space-separated list of the tags associated with the figure. Tags may be used in the GUI displaying a canvas for implementing layers or other kind of filtering.

◆ setTags()

virtual void setTags ( const char * tags )

virtual

Sets the list of tags associated with the figure. This method accepts a space-separated list of tags. (Tags themselves may not contain spaces; underscores are recommended instead where needed.)

◆ getParentFigure()

virtual cFigure* getParentFigure ( ) const

inlinevirtual

Returns the parent figure of this figure, or nullptr if it has none.

◆ getCanvas()

virtual cCanvas* getCanvas ( ) const

virtual

Returns the canvas object to which this figure was added, or nullptr if there is no such canvas. Note that the runtime cost of this method is proportional to the depth of this figure in the figure tree.

◆ getNumFigures()

virtual int getNumFigures ( ) const

inlinevirtual

Returns the number of child figures.

Referenced by cCanvas::getNumFigures().

◆ getFigure() [1/2]

virtual cFigure* getFigure ( int pos ) const

virtual

Returns the kth figure in the child list. The index must be in the range 0..getNumFigures()-1. An out-of-bounds index will cause a runtime error.

Referenced by cCanvas::getFigure().

◆ getFigure() [2/2]

virtual cFigure* getFigure ( const char * name ) const

virtual

Returns the first child figure with the given name, or nullptr if there is no such figure.

◆ findFigure() [1/2]

virtual int findFigure ( const char * name ) const

virtual

Finds the first figure with the given name among the children of this figure, and returns its index. If there is no such figure, -1 is returned.

Referenced by cCanvas::findFigure().

◆ findFigure() [2/2]

virtual int findFigure ( const cFigure * figure ) const

virtual

Finds the given figure among the children of this figure, and returns its index. If it is not found, -1 is returned.

◆ containsFigures()

virtual bool containsFigures ( ) const

inlinevirtual

Returns true if this figure has child figures, and false otherwise.

Referenced by cCanvas::hasFigures().

◆ findFigureRecursively()

virtual cFigure* findFigureRecursively ( const char * name ) const

virtual

Find the first figure with the given name in this figure's subtree, including the figure itself. Returns nullptr if no such figure is found.

Referenced by cCanvas::findFigureRecursively().

◆ getFigureByPath()

virtual cFigure* getFigureByPath ( const char * path ) const

virtual

Finds a figure in the subtree, given by its absolute or relative path. The path is a string of figure names separated by dots; the special module name ^ (caret) stands for the parent figure. If the path starts with a dot or caret, it is understood as relative to this figure, otherwise it is taken to mean an absolute path (i.e. relative to the root figure, see getRootFigure()). Returns nullptr if the figure was not found.

Examples:

"." means this figure;
".icon" means the child figure name "icon";
".group.label" means the "label" child of the "group" child figure;
"^.icon" or ".^.icon" means the "icon" sibling of this figure;
"icon" means the "icon" child of the root figure

The above syntax is similar to the one used by cModule::getModuleByPath()

Referenced by cCanvas::getFigureByPath().

◆ addFigure() [1/2]

virtual void addFigure ( cFigure * figure )

virtual

Appends the given figure to the child list of this figure.

Referenced by cCanvas::addFigure().

◆ addFigure() [2/2]

virtual void addFigure	(	cFigure *	figure,
		int	pos
	)

virtual

Inserts the given figure into the child list of this figure at the given position. Note that relative order in the child list only affects stacking order if the respective figures have the same Z-index.

◆ removeFigure() [1/2]

virtual cFigure* removeFigure ( cFigure * figure )

virtual

Removes the given figure from the child list of this figure. An error is raised if the figure is not a child of this figure.

Prefer removeFromParent() to this method.

Referenced by cCanvas::removeFigure().

◆ removeFigure() [2/2]

virtual cFigure* removeFigure ( int pos )

virtual

Removes the kth figure from the child list of this figure. An error is raised if pos is not in the range 0..getNumFigures()-1.

Prefer removeFromParent() to this method.

◆ removeFromParent()

virtual cFigure* removeFromParent ( )

virtual

Removes this figure from the child list of its parent figure. It has no effect if the figure has no parent figure.

◆ isAbove()

virtual bool isAbove ( const cFigure * figure ) const

virtual

Returns true if this figure is above the given reference figure in stacking order, based on their Z-index values and their relative order in the parent's child list, and false if not. The method throws an error if the two figures are not under the same parent.

◆ isBelow()

virtual bool isBelow ( const cFigure * figure ) const

virtual

Returns true if this figure is below the given reference figure in stacking order, based on their Z-index values and their relative order in the parent's child list, and false if not. The method throws an error if the two figures are not under the same parent.

◆ insertAbove()

virtual void insertAbove ( cFigure * referenceFigure )

virtual

Inserts this figure under the same parent as the reference figure, guaranteeing that it will appear above the reference figure in stacking order. In order to achieve the latter, the Z-index of the figure is set to the Z-index of the reference figure if it was smaller. In case of equal Z-indices, the figure is inserted right after the reference figure. If the Z-index of the figure is already greater than that of the reference figure, nothing should be assumed about the insertion position.

See also: insertAfter()

◆ insertBelow()

virtual void insertBelow ( cFigure * referenceFigure )

virtual

Inserts this figure under the same parent as the reference figure, guaranteeing that it will appear below the reference figure in stacking order. In order to achieve the latter, the Z-index of the figure is set to the Z-index of the reference figure if it was greater. In case of equal Z-indices, the figure is inserted right before the reference figure. If the Z-index of the figure is already smaller than that of the reference figure, nothing should be assumed about the insertion position.

See also: insertBefore()

◆ insertAfter()

virtual void insertAfter ( const cFigure * referenceFigure )

virtual

Inserts this figure after the given reference figure in its parent's child list. BEWARE: Relative order in the child list only affects stacking order if the respective figures have the same Z-index.

◆ insertBefore()

virtual void insertBefore ( const cFigure * referenceFigure )

virtual

Inserts this figure in front of the given reference figure in its parent's child list. BEWARE: Relative order in the child list only affects stacking order if the respective figures have the same Z-index.

◆ raiseAbove()

virtual void raiseAbove ( cFigure * figure )

virtual

If this figure is below the given reference figure in stacking order, move it directly above. This is achieved by updating its Z-index if needed, and moving it in the parent's child list. An error is raised if the two figures do not share the same parent.

◆ lowerBelow()

virtual void lowerBelow ( cFigure * figure )

virtual

If this figure is above the given reference figure in stacking order, move it directly below. This is achieved by updating its Z-index if needed, and moving it in the parent's child list. An error is raised if the two figures do not share the same parent.

◆ raiseToTop()

virtual void raiseToTop ( )

virtual

Raise this figure above all other figures under the same parent. This is achieved by updating its Z-index if needed (setting it to be at least the maximum of the Z-indices of the other figures), and moving it in the parent's child list. It is an error if this figure has no parent.

◆ lowerToBottom()

virtual void lowerToBottom ( )

virtual

Lower this figure below all other figures under the same parent. This is achieved by updating its Z-index if needed (setting it to be at most the minimum of the Z-indices of the other figures), and moving it in the parent's child list. It is an error if this figure has no parent.

◆ dupTree()

virtual cFigure* dupTree ( ) const

virtual

Duplicate the figure subtree.

◆ parse()

virtual void parse ( cProperty * property )

virtual

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 in cPixmapFigure, cImageFigure, cAbstractImageFigure, cLabelFigure, cAbstractTextFigure, cPathFigure, cPolygonFigure, cPieSliceFigure, cRingFigure, cOvalFigure, cRectangleFigure, cAbstractShapeFigure, cPolylineFigure, cArcFigure, cLineFigure, cAbstractLineFigure, and cPanelFigure.

◆ getAllowedPropertyKeys()

virtual const char** getAllowedPropertyKeys ( ) const

virtual

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 in cPixmapFigure, cImageFigure, cAbstractImageFigure, cLabelFigure, cAbstractTextFigure, cPathFigure, cPolygonFigure, cPieSliceFigure, cRingFigure, cOvalFigure, cRectangleFigure, cAbstractShapeFigure, cPolylineFigure, cArcFigure, cLineFigure, cAbstractLineFigure, and cPanelFigure.

◆ moveLocal()

virtual void moveLocal	(	double	dx,
		double	dy
	)

pure virtual

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

Implemented in cAbstractImageFigure, cAbstractTextFigure, cPathFigure, cPolygonFigure, cPieSliceFigure, cRingFigure, cOvalFigure, cRectangleFigure, cPolylineFigure, cArcFigure, cLineFigure, cPanelFigure, and cGroupFigure.

◆ move()

virtual void move	(	double	dx,
		double	dy
	)

virtual

Change the position of this figure and the figures in its subtree by the given x and y deltas. The implementation of this method calls moveLocal() on this figure, then move() recursively on child figures.

Reimplemented in cPanelFigure.

◆ refreshDisplay()

virtual void refreshDisplay ( )

inlinevirtual

This method is invoked by runtime GUIs on every display refresh, and can be overridden if the figure needs to be able to update its contents dynamically (self-refreshing figures.) The changes done inside this method should be restricted to this figure and its subfigure tree.

◆ getRendererClassName()

virtual const char* getRendererClassName ( ) const

pure virtual

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.

Implemented in cPixmapFigure, cIconFigure, cImageFigure, cLabelFigure, cTextFigure, cPathFigure, cPolygonFigure, cPieSliceFigure, cRingFigure, cOvalFigure, cRectangleFigure, cPolylineFigure, cArcFigure, cLineFigure, cPanelFigure, and cGroupFigure.
