Public Attributes
	resetPattern

Protected Attributes
	_device = device

list	_actuators = []
	_reset_button = QtWidgets.QPushButton("Reset", parent=self)

Detailed Description

Display a slider for each actuator.

Constructing this widget will set all actuators to their mid-point
since the actuators position are not queryable..  The reset button
does this too, i.e., it sets all actuators to their mid-point.
