I have a dialog with a dismiss button, the clicked signal of which is linked to
the dialog's accept() slot.
Elsewhere in the dialog I have a QLineEdit that I want the user to be able to
enter a string into. I give the QLineEdit focus with setFocus() at dialog
startup time. This works - when the dialog comes up the cursor is sat blinking
in the QLineEdit and the user can immediately edit the contents as expected.
The problem is that when the user hits the Return key, the Dismiss button sees
it and the dialog gets dismissed. I'm not sure if the keypress is just being
grabbed by the Dismiss button or whether it's propogating upwards to it. Either
way, my question is, what do I need to do to ensure the Return key press is
acted on by the QLineEdit widget, and that widget only?
I should add that when the user has performed their text edit I want to give
focus to the dismiss button. Thus doing the text edit then hitting return twice
should see the edit accepted and the dialog dismissed. I'm having trouble
getting this behaviour.
