我创建了一个python测试程序（Test_InfoPanel.py），其中包含带有dockWidget的MainWindow，以及带有scrollArea小部件的tabWidget。 但是，当我调整MainWindow的大小时，垂直滚动条在
时不会自动出现同样，当我取消停靠dockWidget＆amp;调整大小，垂直滚动条不会自动显示。
请帮助！

#!/usr/bin/env python
# Filename: Test_InfoPanel.py
# Date: 2012-Sep-18
'''
This program test the scrollarea to show scrollbars for the InfoPanel_UI.

PS：我最初创建了mainWindow作为Dialog，但意识到在取消停靠后＆amp; redock，dockWidget没有正确停靠。不知怎的，有一个偏移。如果mainWindow是QtGui.QMainWindow而不是QtGui.QDialog，这似乎不是问题。

ui文件中没有任何布局。不要只是将小部件放到某些位置。使用适当的布局来放置小部件。当您调整大小时，布局将确保小部件正确增长/缩小。
官方文档有using layouts in Qt Designer部分。
