I’m just wondering if it is possible to define a custom widget in IJulia. In Python, this is possible with ipywidgets and, specifically, the widget cookiecutter template – see [https://github.com/jupyter-widgets/widget-cookiecutter](https://github.com/jupyter-widgets/widget-cookiecutter).

Has any tried to do this in Julia?

I’ve added a custom[display widget for waveform display](https://github.com/juliaaudio/sampledsignals.jl#jupyter-notebook-display) just by outputing HTML and javascript in the [`show` method](https://github.com/JuliaAudio/SampledSignals.jl/blob/master/src/WAVDisplay.jl#L22-L116) for MIME type `text/html`.
