Applying New UI Overtop the Existing Main Window

[haroldjclements]

This is a bit of a newbe question: How do you apply a new UI overtop the existing mainwindow?

If I create a new form (newform.ui). Then on a button press, create a new instance
@NewForm nf = new NewForm();@

then initiate the new form:
@nf.show(); @

The new form opens in a new window and not the overtop the mainwindow. I take it that I have to somehow replace the existing form, but I am not too sure how?

Thanks for any help,

Hi and welcome to devnet,

What exactly are you trying to achieve with NewForm ?

Thank you for your reply,

At the moment, I am getting a new window with a title bar, that can be moved around the screen, with the parent form being visible under the new. I want to be able to have only one windows who's content changes and no new windows.

I hope that makes sense!

I think I need to create a widget rather than a form... but I am not too sure...

Thanks again,

OK, found it. I need to setCentralWidget with my new form...

Thanks again,

Depending on what you'll be doing a QStackedWidget as central widget will be more suited
