我创建了一个 python 测试程序 (Test_InfoPanel.py)，它有带 dockWidget 的 MainWindow，在其中有一个带 scrollArea 小部件的 tabWidget。 但是，当我调整 MainWindow 的大小时，垂直滚动条不会在
同样，当我取消停靠 dockWidget 并调整大小时，垂直滚动条不会自动出现。
请帮忙!
测试程序 (Test_InfoPanel.py):
#!/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: 我最初将 mainWindow 创建为对话框，但意识到在取消停靠和重新停靠后，dockWidget 无法正确停靠。不知何故有一个抵消。如果 mainWindow 是 QtGui.QMainWindow 而不是 QtGui.QDialog，这似乎不是问题。
请您参考如下方法:

在命令提示符中使用 pyuic4 -o InfoPanel_UI.py InfoPanel.ui 创建了 *_UI.pt。
使用 Test_InfoPanel.py 运行，仍然显示相同的结果，其中在垂直调整大小时滚动条不显示。 :(
