DockWidget を備えた MainWindow と、その中に scrollArea ウィジェットを備えた tabWidget を持つ Python テスト プログラム (Test_InfoPanel.py) を作成しました。ただし、MainWindow のサイズを変更すると、垂直スクロールバーが自動表示されません。
同様に、dockWidget をドッキング解除してサイズを変更すると、垂直スクロールバーが自動表示されません。
助けてください!

This program test the scrollarea to show scrollbars for the InfoPanel_UI.

PS:最初に mainWindow を Dialog として作成しましたが、ドッキングを解除して再ドッキングした後、dockWidget が適切にドッキングされないことに気付きました。なんとなくズレがあります。mainWindow が QtGui.QDialog ではなく QtGui.QMainWindow である場合、これは問題ではないようです。
