So in both cases the application doesn't do what I want it to do: put the line edit text into the text browser if and only if enter (or tab) is pressed after entering something in that control, and calling the method connected to the button if and only if the button is pressed.

[PyQt] Pressing enter in QLineEdit clicks QPushButton?
Hello, I've got a dialog with a QLineEdit and a QPushButton. The QLineEdit is connected to a method which takes its text and appends it to a QTextBrowser (that's taken from the first GUI example in the PyQt book by M. Summerfield). The clicked() signal of the QPushButton is connected to a method that just prints a message. The problem: this method, which should only be called by clicking the button, is called every time Enter is pressed in the QLineEdit. This happens even if the edit control isn't connected to any method. The button is next to the line edit in the form and in the tab order. With setAutoDefault(false) for this button and for the exit button which follows in tab order I can prevent this behavior, but that isn't really very comfortable.
