Creates a thread-safe lock on this drawer, then calls the following methods in sequence:

Method start_drawing() of this drawer’s style attribute, passing the title and additional keyword arguments obtained from this drawer’s get_style_kwargs()
Method _draw(), passing along the data argument
Method finalize_drawing() of this drawer’s style attribute, passing the keyword arguments obtained from this drawer’s get_style_kwargs()

Parameters

Return type

None

classmethod get_default_style()[source]#

Get the default style for this drawer.

classmethod get_named_styles()#

Get a mapping of names to style factories for all named styles recognized by this drawer’s initializer.

A factory is a class or function with no mandatory parameters.

classmethod get_style(name)#

Get a style object by name.

classmethod get_style_classes()[source]#

Get all style classes available for this drawer type.

get_style_kwargs(data)[source]#

Using the given data object, derive keyword arguments to be passed to the style’s start_drawing() and finalize_drawing() methods.
