【问题描述】：

我正在尝试使用pywinauto 运行大量exe 文件，这些文件将项目添加到现有应用程序。 exe 文件按预期启动，并出现感兴趣的对话框（如下），但我无法单击对话框中的“下一步”按钮。看起来pywinauto 找不到“下一步”按钮。一个想法如何让他工作？这是我的代码：

import time
import pywinauto


def do_installs():
    app = pywinauto.application.Application()
    app.start("You're_a_Hoot_Brushes-(lrd)_windows.exe")

    # setup wizard starts
    # a "Setup" windows appears with a `Next >" button that I want to click

    time.sleep(10)  # excessive wait for Setup dialog

    dlg = app['Setup']
    print('dlg:')
    dlg.print_control_identifiers()
    dlg['Next'].click()


if __name__ == '__main__':
    do_installs()

这是输出日志：

这是我要单击的带有“下一步”的对话框：

标签： python pywinauto

【解决方案1】：

解决方法是不要试图找到按钮。

我能够通过以下方式做我想做的事：

keyboard.send_keys('{ENTER}')

在选择所需选项时按回车键，就像我发布的对话框一样。并且：

dlg.click_input(coords=(x, y))

在其他情况下，在指定坐标处（相对于对话框，dlg）单击鼠标。
