Hi Philip,
As Marcus and Tom have noted the SetUpdateTime() method can be used to set
the display update time (but not the FFT calculation rate, which I think is
what you want).
As this method is a slot it is possible to call it from your application
without any mods to the QT Gui sink, here's a simple example of how to do
it:-
In pyqt_example.py
def __init__(self, display, control):
QtGui.QWidget.__init__(self, None)
self.setWindowTitle('PyQt Test GUI')
self.boxlayout = QtGui.QBoxLayout(QtGui.QBoxLayout.LeftToRight, self)
self.boxlayout.addWidget(display, 1)
self.boxlayout.addWidget(control)
self.resize(800, 500)
#
# Change update rate to 1 second
#
self.connect(self, QtCore.SIGNAL("SetUpdateTime(double)"),
display, QtCore.SLOT("SetUpdateTime(double)"))
self.emit(QtCore.SIGNAL("SetUpdateTime(double)"), 1)
I'm not sure if that's helpful in your case however it may be interesting as
the same technique can be used for any of the slots in spectrumdisplayform.h
