Bases: taurus.qt.qtgui.container.tauruswidget.TaurusWidget
This class is intended to be used as a button to execute macros. The model must be a valid door.
..note:: Not implemented but will be needed: set an icon
..note:
It may be useful to have a slot update_macro_param that any qwidget signal may be
connected to. The only condition might be that the sender widget should have an
attribute 'widget.macro_param_index' in order to determine where the value has
to be added.
..note:
It may be useful to have all the streams from qdoor available somehow
(right-click?)
