python - PyQt4：调整dockWidget大小时，滚动条不显示在滚动区域中

Question

我创建了一个 python 测试程序 (Test_InfoPanel.py)，它有 MainWindow 和 dockWidget，在其中还有一个 tabWidget 和 scrollArea 小部件。但是，当我调整 MainWindow 的大小时，垂直滚动条不会自动出现

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 Dialog，但意识到在 undock & redock 之后，dockWidget 无法正确停靠。不知何故，有一个偏移量。如果 mainWindow 是 QtGui.QMainWindow 而不是 QtGui.QDialog，这似乎不是问题。

ui您在文件中没有任何布局。不要只是将小部件放在某些位置。使用适当的布局来放置小部件。布局将确保小部件在您调整大小时正确增长/缩小。

官方文档有一个在 Qt Designer 中使用布局的部分。
