ABSTRACT
Even though Pyo comes with its own GUI that works very well, there might be some cases where we need to write our own GUI widgets. One such case can be an entry to type numeric values to be passed to an attribute of a PyoObject, instead of calling a function with an argument. Another case could be the need for a selection list, so we can easily select the waveform of an oscillator, or some other feature with many options. A more obvious case is using Pyo with a Python version for which wxPython has no wheels (yet). Pyo being a Python module, can be combined with any existing module for GUI creation.
