Re: [Nuke-python] widget as panel - force one instance only

[Johan Aberg]

If you make sure your widgets are using setObjectName(), you could possibly look up the widgets by name like so to make sure only on instance is running: for widget in QtGui.QApplication.allWidgets()     name = widget.objectName()     if 'myWidgetName' in name:         print name, type(widget) I think the registered panel will be of class <class 'PyQt4.QtGui.QDialog'> and the widget the PyCustom_Knob is pointing to <class 'PyQt4.QtGui.QWidget'> As far as I can see, the panel and widget object will be destroyed when the panel is closed.

My app writes data to disk upon certain events and loads that data again through the widget's constructor. So I need to make sure that only one instance is open at any given time, otherwise I'm running the risk of losing/corrupting that data. Any ideas?
