Signal order
Message 1 in thread
I have a form with a QLineEdit and A QPushButton with the signal:
connect(pushButtonOk,SIGNAL(clicked()),this, SLOT(Move()));
connect(lineEditXInit, SIGNAL(editingFinished()), this,SLOT(Update()));
When I click the button the form must be closed without call Update. The
problem is that first it call the slot connected to editingFinished then
the slot connected to clicked. Can I avoid this?
Thanks

No, but maybe you've got the wrong signal? editingFinished is emitted
whenever you're done typing text into the lineedit, i.e. also if it
looses focus (== clicking a button). So I guess you want some other
signal from the lineedit to connect to your update slot.
Also worth mentioning: The order in which slots are called is not
determined either, that is slots connected to the same signal.
