/**
* @brief The ButtonField class
*
* A UI-type EffectField. This field is largely an EffectField wrapper around a QPushButton and provides no data that's
* usable in the Effect. It's primarily useful for other UI functions (e.g. showing/hiding a dialog or other UI
* elements). This field is not exposed to the external shader API as it requires raw C++ code to connect it to other
* elements.
*
* As with all widgets created from EffectField::CreateWidget(), you should never interface with the resulting widget
* directly (apart from adding it to a layout and deleting it when it's unnecessary). All signals/slots should pass
* through ButtonField instead to keep consistency with every layer involved.

* mode this field still cannot be used as a value in an Effect. Instead use BoolField (which uses a QCheckBox
* representation) for passing values to the Effect that can only be true or false.
