if __name__ == "__main__": 
    import sys 
    app = QtGui.QApplication(sys.argv) 
    Dialog = QtGui.QDialog() 
    ui = Ui_Dialog() 
    ui.setupUi(Dialog) 
    Dialog.show() 
    sys.exit(app.exec_())

的输出是在屏幕截图：问题是，TAB1没有显示任何滚动条甚至我scrollArea下设置的布局。我期待滚动条的区域以红色矩形显示。

我记得:-) How to associate a horizontal scrollbar to multiple groupbox.?

你仍然没有得到适当的滚动条的原因是因为scrollarea内你的部件没有一个最小高度，并且被允许远远不够缩小这种类似的问题他们永远不会强制Scrollarea显示其滚动条。

在代码中，你可以解决这个问题：

self.dockWidgetContents.setMinimumHeight(100)

Althought，你不应该做任何直接编辑这个文件，从Qt Designer的产生。你应该做的是进入QtDesigner，选择小部件，并在他们的属性列表顶部，为他们设置一个最小高度。

工作完美的男人。但这是另一个问题。出于某种原因，我必须更改我的对话框的内容。而不是dockWidget我使用了一个groupBox，在这种情况下设置最小高度不起作用。你能解释一下为什么或者你想要我发布整个代码吗？感谢您的帮助 – Jack 2012-03-22 01:31:37

可以在这里找到一小部分代码[链接]（http://pastebin.com/KUVWxDCg） – Jack 2012-03-22 01:44:56

这段代码中没有足够的上下文让我确切地知道，但是，QGroupBox是一个QWidget的子类与dockWidget或其他任何东西都是一样的。固定高度是一个QWidget属性。所以它应该都是一样的功能。如果不是，那么你在子部件和他们在 – jdi 2012-03-22 05:25:01
