create_shape()[source]¶

Create the toolkit shape for the proxy object.

This method is called during the top-down pass, just before the ‘init_shape()’ method is called. This method should create the toolkit widget and assign it to the ‘widget’ attribute.

doc¶: The document

extract_shapes(doc, page)[source]¶: Parse shapes from the pdf page

f¶: File

reference¶: Update the class reference

shape¶: Make wire
