[Qt-interest] How Do I get QTabWidget in resizable dialog to stretch with dialog?

[kent williams]

I'm having a heck of a time getting a complicated dialog to look nice.

The organization is

QDialog                     -- the dialog
  QTabWidget            -- tabwidget to contain one or more forms
     QVerticalForm      -- each form a vertical list of name/value pairs
        QFormLayout

The problem is that when I resize the dialog the QTabWidget doesn't
resize with the dialog.  How do I get it to resize with the dialog?

The forms are created at runtime and added to the QTabWidget, and
Dialog itself was built with Designer.
