CheckBox A checkbox directly interacting with a process parameter.
Digital A digital display.
DoubleSpinBox A spinbox displaying a floating-point process parameter.

Led A simple LED widget that displays a truth value.
MultiLed A more sophisticated LED widget that can have value-specific colors and blink states.
PushButton A pushbutton either creating an event or a state in the process.
