Looks like the problem is not with the Test widget, but with the initial size of MainWindow. What if you set the initial size of MainWindow to whatever is defined in Test.sizeHint() in MainWindow.__init__() ? This way, the MainWindow will start at the size needed to hold the Test widget at full size, but it will still allow the Test widget to be smaller if user so desires.

The Test widget will have the minimum size specified by the sizeHint, and yet the MainWindow can still grow. Thank you for the suggestion. I actually had tried that, but it is unfortunately not an acceptable solution because I need to allow the user to make the size smaller than the original specification. The exact use case is defining a plot canvas in matplotlib. Darren ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

[PyQt] question about size hints
I have a question about size hints that can be illustrated with the simple example below. If I create my Test widget so it returns a size hint of (200,100), it is rendered with a size of 200, 100. If I create Test so it is 100x70, it is rendered to be 200x100. If I create test to be 1000x700, it is rendered to be 853x533 (my screen resolution is 1280x800). If I set the size policy to be fixed, then the central widget size policy is respected, but I can't resize the window. How can I make m respect the size hint of the central widget, but still maintain the ability to resize the window?
