我已经使用 PyQt 设计器设置了简单的示例。见下文。我有 mdiarea,我在其中添加了一个表单作为子窗口。我制作的表格比主窗口长一点,以查看子子窗口是否出现滚动条。
问题:
如果我将 mdiarea 设置为setViewMode(QtGui.QMdiArea.TabbedView)
滚动条停止工作并消失。Howeevr 如果我不使用 TabbedView,滚动条可以正常工作。谁能告诉我怎么了?我需要带有工作滚动条的 mdiarea 的 TabbedView。
我在 win7 上使用 Python 2.7、PyQT 4.8.4/PySide 1.2.1。
Python 示例代码: 注释 self.mdiArea.setViewMode 行以查看示例工作。
