Methods defined here:
OnDestroy(self, widget=None)
This method sets the preview pipeline to gst.STATE_NULL.
 
Parameters:
        widget -- reserved for GTK callbacks, don't use it explicitly.
OnEOS(self, bus, message)
Called when the preview stream ends. It deactives the AudioPreview.
 
Parameters:
        bus -- reserved for GStreamer callbacks, dont't use it explicitly.
        message -- reserved for GStreamer callbacks, dont't use it explicitly.
OnSelection(self, widget)
This method is called when a user selects a new file in the import audio file dialog. 
The preview widget then retrieves the location of the file that has been selected
and sets the variable self.uri to be the location of the file it retrieves.
 
Parameters:
        widget -- reserved for GTK callbacks, don't use it explicitly.
OnToggle(self, widget)
This method is called when a user toggles the preview button between a stop
or playing state. It will then set the button to appear pressed in when playing
or normal when stopped.
 
Parameters:
        widget -- reserved for GTK callbacks, dont't use it explicitly.
__init__(self)
Creates a new instance of AudioPreview.
