Window to Window QT Creator

[csstudent123]

Assume, I have a form with a single button "enter".
Now what I want is when I push enter I want another new form with other components. But I do not want the old window behind. How can I do this?

Thanks

Hide old window.

Thanks, I imagine the same logic applies in QT Creator or Visual Studio...
