Actually I am using the object name as the name of a property in another class in order to use the "setProperty()" methods to set that particular property. I can get the name of the object who signaled the current method (which is a slot itself). Based on that name I know what property to set. This is straight forward with things like spin boxes and check boxes. The current layout for an "Input File" has both a QLineEdit and a QPushButton. Either can set the property. The QPushButton through a File Open dialog and the QLineEdit through a raw path specification. The Guis are dynamically created otherwise this would be much simpler. And things like "findChild" uses the object name. I'll have to rethink my design as this seems like an edge case where the outcome is undefined.

THanks for the quick feedback everyone.
