使用部分ti的Python pywinauto搜索窗口

有没有办法让pywinauto找到一个只包含部分标题的窗口?

这是我的代码:

import pywinauto

pwa_app = pywinauto.application.Application()
w_handle = pywinauto.findwindows.find_windows(title=u'Minitab Professional 5.1 64bit - 3333348.temp.project',
                                              class_name='Window')[0]

问题是每次打开软件时,temp.project之前的数字都会改变,因此我无法让pywinauto找到正确的窗口。

title_re作为Python正则表达式工作。在你的情况下应该是title_re=u'Minitab Professional 5\.1 64bit - \d+\.temp\.project'

\.表示点符号,.表示任何符号。

对于全功能对话框包装器(而不是句柄),下面的事情更简单:

dlg = pwa_app.Window_(title_re=u'Minitab Professional 5\.1 64bit - \d+\.temp\.project', class_name='Window')

它用适当的process参数(这是pid)调用find_window,因此您不会被来自多个应用程序实例的许多类似窗口所混淆。

顺便说一下,对于64位应用程序,您需要64位兼容的pywinauto克隆(官方的0.4.2只支持32位Python和应用程序,因为不同的WinAPI结构对齐方式)。

在这种情况下,最好通过路径连接到应用程序,例如:

app = application.Application(backend="uia")
app.connect(path = r"C:/Program Files/iTunes/iTunes.exe")

通过浏览google code上的源代码,我发现您可以为标题提供regex:

#=========================================================================
def find_windows(class_name = None,
                class_name_re = None,
                parent = None,
                process = None,
                title = None,
                title_re = None,
                top_level_only = True,
                visible_only = True,
                enabled_only = False,
                best_match = None,
                handle = None,
                ctrl_index = None,
                predicate_func = None,
                active_only = False,
                control_id = None,
    ):
    """Find windows based on criteria passed in

    Possible values are:

    * **class_name**  Windows with this window class
    * **class_name_re**  Windows whose class match this regular expression
    * **parent**    Windows that are children of this
    * **process**   Windows running in this process
    * **title**     Windows with this Text
    * **title_re**  Windows whose Text match this regular expression
    * **top_level_only** Top level windows only (default=True)
    * **visible_only**   Visible windows only (default=True)
    * **enabled_only**   Enabled windows only (default=True)
    * **best_match**  Windows with a title similar to this
    * **handle**      The handle of the window to return
    * **ctrl_index**  The index of the child window to return
    * **active_only**  Active windows only (default=False)
    * **control_id**  Windows with this control id
   """

据我所知,pywinauto.findwindows.find_windows(title_re = r'Minitab Professional 5.1 64bit*', class_name='Window')[0]应该有用。
