sheet

classmethod from_xml(xml: str)

Load self from XML.

get_style(obj) → CSSStyleDeclaration

Get the style of an object.

This is prefered over accessing the style attribute directly, sicne it includes class and pdgid definitions.

to_xml() → str

Return self as XML.

with_default_style(value, k='default_style')

Set default_style to value and return self.

with_labels(value, k='labels')

Set labels to value and return self.

with_legs(value, k='legs')

Set legs to value and return self.

with_propagators(value, k='propagators')

Set propagators to value and return self.

with_sheet(value, k='sheet')

Set sheet to value and return self.

with_vertices(value, k='vertices')

Set vertices to value and return self.
