Title, author, and description parameters are for identification purposes. The window size controls the dimensions of the flow graph editor. \ The window size (width, height) must be between (300, 300) and (2048, 2048). The generate options controls the type of code generated. \ Non-graphical flow graphs should avoid using graphical sinks or graphical variable controls. The id of this block determines the name of the generated file and the name of the class. \ For example, an id of my_block will generate the file my_block.py and class my_block(gr....
