Python 从快速 GUI 编程错误中查找并替换对话框

Question

从 "Rapid GUI Programming with Python and Qt (Chapter 07), by Prentice Hall (Mark Sumerfield)" 构建查找和替换对话框时，出现以下错误：

    import ui_findandreplacedlg
ImportError: No module named ui_findandreplacedlg

根据python我运行的哪个版本，我还得到：

File "findandreplacedlg.py", line 7, in <module>  
    ui_findandreplacedlg.Ui_FindAndReplaceDlg):  
AttributeError: 'module' object has no attribute 'Ui_FindAndReplaceDlg'

我从他们的网站上获得了源代码，它以同样的方式在同一行出错。我在他们的网页上搜索了勘误表，但没有任何提及。有谁知道解决方案是什么？

Answer 1

相关代码可在此处找到 - https://github.com/suzp1984/pyqt5-book-code/blob/master/chap07/ui_findandreplacedlg.py。如果该文件与您尝试运行的代码位于同一目录中，只需执行

import ui_findandreplacedlg

Answer 2

您需要使用 pyuic 工具转换 ui 文件。这在书中解释如下（第 206 页）：

Once a user interface has been designed and saved in a .ui file, it must be con- verted into code before it can be used. This is done using the pyuic4 command- line program. For example:
C:\pyqt\chap07>pyuic4 -o ui_findandreplacedlg.py findandreplacedlg.ui

或者如果您在 Linux:

$ cd pyqt/chap07
$ pyuic4 -o ui_findandreplacedlg.py findandreplacedlg.ui
$ python findandreplacedlg.py
