Pywinauto:无法将窗口带到前台

Question

使用基于Python的自动化工具.

想象一下,有一个运行的应用程序池:

APPS_POOL = ['Chrome', 'SomeApp', 'Foo']

该脚本在循环中运行(每秒)并需要在它们之间随机切换:

# Init App object
app = application.Application()

# Select random app from the pull of apps
random_app = random.choice(APPS_POOL)
app.connect(title_re=".*%s" % random_app)
print 'Select "%s"' % random_app

# Access app's window object
app_dialog = app.window_(title_re=".*%s.*" % random_app)

if app_dialog.Exists():
    app_dialog.SetFocus()

第一次它工作正常,但每隔一个 - 窗口不会被带到前台.有任何想法吗？

编辑:脚本从Win7 CMD运行.一旦将焦点设置为其他窗口,系统是否有可能"阻止"CMD以某种方式设置焦点？

Answer 1

我觉得这SetFocus有点儿麻烦.至少在我的机器上我得到一个错误:error: (87, 'AttachThreadInput', 'The parameter is incorrect.').所以也许你可以玩最小化/恢复.请注意,这种方法也不是防弹.

import random
import time
from pywinauto import application
from pywinauto.findwindows import WindowAmbiguousError, WindowNotFoundError

APPS_POOL = ['Chrome', 'GVIM', 'Notepad', 'Calculator', 'SourceTree', 'Outlook']


# Select random app from the pull of apps
def show_rand_app():
    # Init App object
    app = application.Application()

    random_app = random.choice(APPS_POOL)
    try:
        print 'Select "%s"' % random_app
        app.connect(title_re=".*%s.*" % random_app)

        # Access app's window object
        app_dialog = app.top_window_()

        app_dialog.Minimize()
        app_dialog.Restore()
        #app_dialog.SetFocus()
    except(WindowNotFoundError):
        print '"%s" not found' % random_app
        pass
    except(WindowAmbiguousError):
        print 'There are too many "%s" windows found' % random_app
        pass

for i in range(15):
    show_rand_app()
    time.sleep(0.3)

上面一个是完美的答案，但是不推荐使用 HasStyle 新方法如下

if m.has_style(win32defines.WS_MINIMIZE): # if minimized
    ShowWindow(m.wrapper_object(), 9) # restore window state
else:
    SetForegroundWindow(m.wrapper_object()) #bring to front

......另一种处理方式......

app = Application(backend='win32').connect(path="")
app.top_window().set_focus()
