This block creates a variable with a choice of widgets. The ID will be the variable name, so that ID can be used as a parameter in another block to make it adjustable in real-time.
Leave the label blank to use the variable id as the label.
This block does not support C++ output, so it cannot be used when the output language of a flowgraph in GRC is C++.
Parameters
