PySide如何查看应用程序版本信息

Question

我用 Python (PySide) + PyInstaller 创建了 EXE 文件。一旦我尝试使用

print QtGui.QApplication.applicationVersion()

我没有看到应用程序 x.x.x.x 格式的有效版本。

PySide 中是否有任何内置函数而不是这个，或者我应该使用其他库吗？

PS. 我不相信 Python 没有任何方法来提取有关 EXE 的信息:)

找到一种方法：

import win32api    

def get_version_info():
    try:
        filename = APP_FILENAME
        return get_file_properties(filename)['FileVersion']
    except BaseException, err:
        log_error(err.message)
        return '0.0.0.0'

def get_file_properties(filename):
    """
    Read all properties of the given file return them as a dictionary.
    """
    propNames = ('Comments', 'InternalName', 'ProductName',
        'CompanyName', 'LegalCopyright', 'ProductVersion',
        'FileDescription', 'LegalTrademarks', 'PrivateBuild',
        'FileVersion', 'OriginalFilename', 'SpecialBuild')

    props = {'FixedFileInfo': None, 'StringFileInfo': None, 'FileVersion': '0.0.0.0'}

    try:
        # backslash as parm returns dictionary of numeric info corresponding to VS_FIXEDFILEINFO struc
        print filename
        fixedInfo = win32api.GetFileVersionInfo(filename, '\')
        props['FixedFileInfo'] = fixedInfo
        props['FileVersion'] = "%d.%d.%d.%d" % (fixedInfo['FileVersionMS'] / 65536,
                fixedInfo['FileVersionMS'] % 65536, fixedInfo['FileVersionLS'] / 65536,
                fixedInfo['FileVersionLS'] % 65536)

        # \VarFileInfo\Translation returns list of available (language, codepage)
        # pairs that can be used to retreive string info. We are using only the first pair.
        lang, codepage = win32api.GetFileVersionInfo(filename, '\VarFileInfo\Translation')[0]

        # any other must be of the form \StringfileInfo\%04X%04X\parm_name, middle
        # two are language/codepage pair returned from above

        strInfo = {}
        for propName in propNames:
            strInfoPath = u'\StringFileInfo\%04X%04X\%s' % (lang, codepage, propName)
            ## print str_info
            strInfo[propName] = win32api.GetFileVersionInfo(filename, strInfoPath)

        props['StringFileInfo'] = strInfo
    except BaseException, err:
        log_error(err.message)
    return props
