How to make different pages of a QStackedWidget of different sizes?

pyqt, qstackedwidget, qt

Solution

You can set the size policy of the page that is displayed to `QSizePolicy.Preferred` and the other ones to `QSizePolicy.Ignored`. After that call `adjustSize` to update the sizes. For example when you set the current index to show `page1` :

page1.setSizePolicy(QSizePolicy.Preferred, QSizePolicy.Preferred)
page2.setSizePolicy(QSizePolicy.Ignored, QSizePolicy.Ignored)

stackedWidget.adjustSize()
adjustSize()

And when the other page is shown, set the size policies the other way.

Problem

I have a `QStackWidget` with 2 pages. One page contains just 2 `QLineEdit` widget and another page contains a large `QTextEdit`. Does anyone know how to make one page larger than another so that the window still fits tightly for each page? In the Qt Designer, the `QStackWidget` has to take the larger size in order to first the `QTextEdit`, but then the page with the `QLineEdit` widgets would be way too big. Thanks
