问题 I'm trying to create a method for my class, which inherits from data.frame.

Exactly the same as this question here, but since that answer doesn't solve my problem, I decided to ask again.

According to it, void QWidget::show () [slot] Shows the widget and its child widgets.

问题 I am designing an installer interface for a already written program. It is my first windows.form. I see three approaches to solving my "problem" of needing multiple "screens".
