Hi André, I don't use blockSignals because the side effects are undocumented. The problem is that ALL signals are blocked, not just the specific call to your slot. Lots of things rely on the changed signal from QLineEdit - attached models and complex widgets, like QComboBox, for example. Also, from reading the Qt code in general, there is often a complex web of internal signals between the public and private interfaces, and I've always assumed they are affected as well (?).
