GraphElem

The GraphElem is the base class for all representations of graph elements: entities, junctors, groups and edges. This class has variables and methods common to all elements.

Fields

Field	Type	Description
eid	integer	Read only. Unique integer assigned to each GraphElem.
isEntity	boolean	Read only. Returns False (see Entity.)
isJunctor	boolean	Read only. Returns False (see Junctor.)
isGroup	boolean	Read only. Returns False (see Group.)
isEdge	boolean	Read only. Returns False (see Edge.)
canHaveParent	boolean	Read only. Returns False (see VertexElem.)
hasParent	boolean	Read only. Returns True if has parent.
frame	tuple	Read only. The element’s bounds as a tuple (left, top, width, height), or (0, 0, 0, 0) if the element is hidden in a collapsed group.
annotation	string or None	The annotation (note) of the element, an HTML document as a string, or None if the element has no note. If set to plain text, the font of the annotation defaults to Monospaced/12.
isHiddenInCollapse	boolean	Returns True if the element is in a collapsed group, otherwise False.
hasAnnotation	boolean	Returns True if the element has an annotation, otherwise False.
annotationNumber	integer	Read only. The annotation (note) number of the element, an integer, or zero if the element has no note.
displayAnnotationNumber	integer	Read only. The annotation (note) number of the element if note numbers are displayed as an integer, or zero if the element has no note or note numbers are not displayed.
partFrames	dictionary	Read only. A dictionary of tuples (x, y, width, height). The keys are Shape Part Types for visual elements that vary by GraphElem type and state.
plainAnnotation	string or None	Read only. the annotation (note) of the element as plain text, or None if the element has no note.
annotationEditor	TextEditor	Returns a TextEditor instance which allows for modification of the annotation, or None if the element has no note (variable is read only, the TextEditor itself can be modified).
user	dictionary	A dictionary containing user defined attributes (variable is read only, the dictionary itself can be modified) Example: previousFacility = elem.user['facility']; elem.user['facility'] = 'Los Angeles'; del elem.user['careless']
