Show a plugin's user interface
Matthew John Yee-King · Focal Press eBooks · 2024
The final functional change we will make to our plugin host before we switch back to working on the machine learning side is to display the user interface for the plugin. This chapter explains how to display the user interface for any plugin. One of the features of the various plugin APIs (VST3, AudioUnit, etc.) is that they allow the plugin to have a custom user interface. This is the interface you see when you load the plugin into your DAW. As you should know by now, JUCE allows you to write a custom GUI for your plugins using the JUCE GUI widgets. Commercial and other plugins have their own ways of implementing the GUI, including animated graphics, 3D, etc. How can we show this user interface using JUCE? The solution presented here is to pop up a free-floating window containing the user interface. To achieve that, you are going to explore the JUCE API a little more and define a new class.
