Auto text edit field focus about memento

[ripose-jp]

I'm on board with the idea. My only criticism is you can do all of this

if (m_ui->widgetFind->isVisible())
{
    widgetFind->findChild<QLineEdit*>("lineEditSearch")->setFocus();
}

with this

m_ui->lineEditSearch->setFocus();

If you want to make a pull request, I'll merge it. If not I can do it myself.

I'd certainly make a fixed PR. The only thing is whether you want the same thing to be done for SearchWidget, which I feel is also more complex after a bit of poking.

[ripose-jp]

Doing the same for SearchWidget is not any more complex than this one. I would say that if you did choose to include SearchWidget, make the change in a separate commit and move the implementation for showEvent into the cpp file.

Better yet, you can just connect the widgetShown signal to setFocus and leave showEvent where it is.
