Hi
You said:

but a message pops up.

Your own messageBox comes again when you close dialog
or is it a new message ? ( not yours)

@mrjj @Asperamanca

focusOutEvent of lineEdit

focusOutEvent(QFocusEvent* event)
{
QMessageBox::warning(this,tr("message"),"message",QMessageBox::OK);
// Because, if user enters the wrong value in lineEdit
}

I click cancel button (to close dialog)
my lineEdit is focusOut
call focusOutEvent
pop up a message.

I want to keep the message out.

@kwanyoung I think what you want to achive can better be done with a QValidator assigned to the lineEdit.

And please: no messagebox! thats bad user experience. disable the dialogs Ok button, show an status message in the dialog, but no messagebox. thanks :)
