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 (4096, 4096). The generate options controls the type of code generated. \ Non-graphical flow graphs should avoid using graphical sinks or graphical variable controls. In a graphical application, \ run can be controlled by a variable to start and stop the flowgraph at runtime. 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.... The category parameter determines the placement of the block in the block selection window. \ The category only applies when creating hier blocks. \ To put hier blocks into the root category, enter / for the category. </doc> </block>
