class umbra.ui.nodes.Mixin_GraphModelObject

Bases: object

This class is a mixin used to bring common capabilities in Application Nodes classes.

roles

This method is the property for self.__roles attribute.

Returns:self.__roles. ( Dictionary )

flags

This method is the property for self.__flags attribute.

Returns:self.__flags. ( Integer )

triggerModel

This method is the property for self.__triggerModel attribute.

Returns:self.__triggerModel. ( Boolean )

class umbra.ui.nodes.GraphModelAttribute(name=None, value=None, roles=None, flags=None, **kwargs)

Bases: foundations.nodes.Attribute, umbra.ui.nodes.Mixin_GraphModelObject

This class represents a storage object for the GraphModelNode class attributes.

Parameters:

• name – Attribute name. ( String )
• value – Attribute value. ( Object )
• roles – Roles. ( Dictionary )
• flags – Flags. ( Integer )
• **kwargs – Keywords arguments. ( ** )

attributeChanged()

This method triggers the host model(s) umbra.ui.models.GraphModel.attributeChanged() method.

Returns:Method success. ( Boolean )

class umbra.ui.nodes.GraphModelNode(name=None, parent=None, children=None, roles=None, flags=None, **kwargs)

Bases: foundations.nodes.AbstractCompositeNode, umbra.ui.nodes.Mixin_GraphModelObject

This class defines GraphModel class base Node object.

Parameters:

• name – Node name. ( String )
• parent – Node parent. ( AbstractNode / AbstractCompositeNode )
• children – Children. ( List )
• roles – Roles. ( Dictionary )
• flags – Flags. ( Qt.ItemFlag )
• **kwargs – Keywords arguments. ( ** )

nodeChanged()

This method triggers the host model(s) umbra.ui.models.GraphModel.nodeChanged() method.

Returns:Method success. ( Boolean )

class umbra.ui.nodes.DefaultNode(name=None, parent=None, children=None, **kwargs)

Bases: foundations.nodes.AbstractCompositeNode

This class defines the default Node used in GraphModel class model.

This simple Node is used as an invisible root Node for GraphModel class models.

Parameters:

• name – Node name. ( String )
• parent – Node parent. ( AbstractCompositeNode )
• children – Children. ( List )
• **kwargs – Keywords arguments. ( ** )

class umbra.ui.nodes.FormatNode(name=None, parent=None, children=None, format=None, **kwargs)

Bases: foundations.nodes.AbstractCompositeNode

This class defines the format base Node object.

Parameters:

• name – Node name. ( String )
• parent – Node parent. ( AbstractNode / AbstractCompositeNode )
• children – Children. ( List )
• format – Format. ( Object )
• **kwargs – Keywords arguments. ( ** )

format

This method is the property for self.__format attribute.

Returns:self.__format. ( Object )
