"""
Creates a new MplQT4TimeFreqWindow, which controls interaction
with Nutmeg TFBeam objects. This window is a QT4TopLevelAuxiliaryWindow,
giving it top level status. It contains:
*a 2D image of the time-frequency plane with selectable bins (emits a
functional image update event and a tf event, described below)
*a TFBeam management panel, with data management and feature
localizations (events described below)
*a threshold management panel, to create different mask criteria
Time-frequency point updates cause emission of the tf_point signal.
To cause methods to be connected to this signal, include them in the
tf_connections iterable argument. Methods will have this signature
pattern:
meth(timept, freq_a, freq_b)
Overlay image updates are also signalled. To cause methods to be
connected, include them in the image_connections iterable argument.
Methods will have this signature pattern:
meth(obj)
* obj will give access to obj.overlay, obj.alpha,
* obj.norm, obj.fill_value
Spatial location updates cause emission of the xyz_point signal. To
cause methods to be connected to this signal, include them in the
loc_connections interable argument. Methods will have this signature
pattern:
meth(x, y, z)
Parameters
----------
loc_connections: iterable
Methods to connect to the xyz_point signal
image_connections: iterable
Methods to connect to the new_image signal
parent: QObject (optional)
A QT4 QObject to set as the parent of this widget (thus causing
this widget NOT to run as a top level window)
main_ref: QObject (optional)
A QT4 QObject to be considered as the "parent" of this widget,
when this widget is running as a top level window
tfbeam: TFBeam (optional)
A TFBeam with which to preload the beam manager.
**kwargs:
figsize, dpi for the time-frequency plane figure
