Detailed Description

template<class ComponentType, typename ValueType>
class hise::raw::UIConnection::Base< ComponentType, ValueType >

The base class for the connection implementation of each UI widget.

There are three available UI widgets: the ComboBox, the Slider and the Button.

If you need more UI widgets or hook them up to your own classes, make sure that:

1. The class is derived from juce::Component
2. It has a subclass called Listener and the methods addListener() and removeListener()
3. the Listener subclass has a virtual callback that gets overwritten to change the Processor's parameter (take a look at the implementations to get a feeling how this works).
4. Overwrite the method updateUI() to reflect the change on your UI widget. This is important to match the displayed value when the parameter is changed externally, eg. by loading presets or automation.
