Loading a simple Qt Designer form in to Pyside
提问by Kamil Kisiel
I create a simple form in Qt designer and am trying to load it in to a Qt application I'm creating with PySide but without much luck.
我在 Qt 设计器中创建了一个简单的表单，并试图将它加载到我使用 PySide 创建的 Qt 应用程序中，但运气不佳。
Here's the generated code from `pyside-uic':
这是从“pyside-uic”生成的代码：
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'clientEditorForm.ui'

# Created: Tue Nov 3 23:46:41 2009

app = QtGui.QApplication(sys.argv)
myapp = MyMainWindow()
myapp.show()
sys.exit(app.exec_())
However, when I try to run it, I get the following:
但是，当我尝试运行它时，我得到以下信息：
QLayout: Attempting to add QLayout "" to QMainWindow "clientEditorForm", which already has a layout
and a segmentation fault. I'm following the basic instructions in this tutorialbut I can't tell what I'm doing wrong.
和分段错误。我正在遵循本教程中的基本说明，但我不知道我做错了什么。

Turns out there is a bug in PySide with the QSpacerItem class. Commenting out the QSpacerItem instances in the code above makes it work just fine. There's a bug report on the PySide bugzilla.
结果发现 PySide 中的 QSpacerItem 类存在一个错误。注释掉上面代码中的 QSpacerItem 实例使其工作得很好。PySide bugzilla上有一个错误报告。

Firstly you are using PySide(Nokia) not PyQt4(Riverbank Computing), although their API's are nearly identical they are not the same project. The PySide examples are available here: git clone git://gitorious.org/pyside/pyside-examples.git
首先，您使用的是 PySide（诺基亚）而不是 PyQt4（Riverbank Computing），尽管它们的 API 几乎相同，但它们不是同一个项目。PySide 示例可在此处获得： git clone git://gitorious.org/pyside/pyside-examples.git
I think the problem may have to do with your call of
我认为问题可能与您的电话有关
super(MyMainWindow, self).__init__(parent)
try
尝试
QtGui.QMainWindow.__init__(self, parent)
instead.
反而。
I know it seems like it is the same thing, but I've ran into similar problems with super using PyQt4, and from what I can tell Nokia's PySide has the same troubles. It has something to do with weather the Python owns the parent or it's owned by an underlying C++ object. At least give it a try, it'll take less than 5 seconds!
我知道这似乎是一回事，但我在使用 PyQt4 时遇到了类似的问题，据我所知，诺基亚的 PySide 也有同样的问题。它与天气有关，Python 拥有父对象或它由底层 C++ 对象拥有。至少试一试，不到 5 秒！
Below is the example I'm basing this off of, it's from the git repo for PySide.
下面是我以此为基础的示例，它来自 PySide 的 git 存储库。
