PyQt小部件边缘切断

我正在制作一个小脚本，其中xterm嵌入在一个小GUI中。当我运行我的尝试时，终端小部件的边缘被切断，我不知道为什么。我怎样才能显示完整的终端？PyQt小部件边缘切断

这是因为terminal widget是大于xterm窗口。您可以通过

self.terminal = QtGui.QTextBrowser() 
self.terminal.setFrameStyle(QtGui.QTextEdit.DrawWindowBackground)

更换

self.terminal = QtGui.QWidget()

，看看你的terminal的实际大小。我已经找到了解决办法是设置terminal接近xterm窗口大小初始大小：

self.terminal.setFixedSize(730, 440)

嗨@Alexander Lutsenko的。感谢您的解决方案，该解决方案运行良好，并为您解释如何考虑终端的大小。 – d3pd

你QWidget有一个相关的QVerticalLayout，所以要根据文件似乎在默认情况下它延伸仅垂直，所以你应该手动设置大小的策略。尝试是这样的：

self.terminal.setSizePolicy(QSizePolicy.Expanding, QSizePolicy.Expanding)
