Pywinauto不响应

Question

我是python和pywinauto的新手，我需要用pywinauto和Chrome_widgetWin_1在Chrome中开始一个演示文稿，在我运行了一个程序后- Chrome启动了，但只显示了一个新的标签，演示文稿没有出现。

程序的第一部分调用pdf a html演示文稿并添加到Chrome的路径，第二部分是调用一些Chrome小工具来启动演示文稿，但显然它不起作用。

我不知道有什么问题，因为到目前为止我还没有在那里工作过，在互联网上也没有什么有用的东西。

有没有人对此有什么经验呢？感谢您的帮助，tnx :)

pdf = "\\CIT_presentation.pdf"         
htmlpres = "file:///...template_cit2.html#1"    
adobe = "C:\Program Files (x86)\Adobe\Reader 11.0\Reader\AcroRd32.exe"    
chrome = "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"    
import xml.etree.ElementTree as ET    
from suds.client import Client
class Presentation:    
    def start(self):    
        from pywinauto import application    
        app = application.Application()    
        app.start_(chrome)    
        pwa_app = pywinauto.application.Application()    
        while True:    
            try:    
                w_handle =     pywinauto.findwindows.find_windows(class_name='Chrome_WidgetWin_1')[0]    
                window = pwa_app.window_(handle=w_handle)    
                window.TypeKeys(htmlpres, with_spaces = True)    
                window.TypeKeys("~")    
                break    
            except:    
                pass

Answer 1

您可能混淆了两个应用程序对象：app和pwa_app。app与启动的chrome.exe进程相关，pwa_app并没有连接到任何进程，它只是一个来自SWAPY工具的“复制-粘贴”。

只需删除行pwa_app = pywinauto.application.Application()，并将所有pwa_app对象替换为app对象。

edit1以防万一..。您需要32位Python 2.7。

试着理解这个问题..首先，让我们通过以下方式使该代码能够实际运行：

import pywinauto
import time
import sys

htmlpres = "zcuba.dk/2014" 

chrome = "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"

class Presentation:
    def __init__(self):
        pass

    def start(self):     
        app = pywinauto.application.Application()    
        app.start_(chrome)    
        pwa_app = pywinauto.application.Application()    
        while True:    
            try:    
                w_handle = pywinauto.findwindows.find_windows(class_name='Chrome_WidgetWin_1')[0]
                window = pwa_app.window_(handle=w_handle)
                window.TypeKeys(htmlpres, with_spaces = True)      
                window.TypeKeys("~")   
                window.TypeKeys("{F11}") 
                break;
            except:
                e = sys.exc_info()[0]
                print e
                time.sleep(1)

p = Presentation()
p.start()

现在它在这里工作了，我找不到任何错误...抱歉的

下一个调试版本的代码，它看起来不像你的原始版本，并且有很多输出可以帮助你找出你的问题！

import pywinauto
import time
import sys

htmlpres = "zcuba.dk/2014" 

chrome = r'C:\Program Files (x86)\Google\Chrome\Application\chrome.exe'

class Presentation:
    def __init__(self):
        pass

    def start(self):
        print "starting the pywinauto application object, by default construction"
        pwa_app = pywinauto.application.Application()

        print "start chrome, via pywinauto, without parameters, for later interaction"
        pwa_app.start_(chrome)

        print "now I'll attempt to communicate with the chrome instance"
        while True:    
            try:
                print "find the first windows application, that has an open window, with the class name 'Chrome_WidgetWin_1' (typically a chrome tab/window instance)"
                w_handle =     pywinauto.findwindows.find_windows(class_name='Chrome_WidgetWin_1')[0]
                print "assigned a handle to the applications window:"
                print "handle is: " + str(w_handle)
                print "use the handle to create a window automation object"
                window = pwa_app.window_(handle=w_handle)
                print "window object created:"
                print window

                print "Now, attempt to simulate keyboard, and write the address in the chrome window (wherever focus is - we assume it is in the address bar - but some extensions can change this behaviour)"
                window.TypeKeys(htmlpres, with_spaces = True)      
                print "pressing enter to start the search for the address entered"
                window.TypeKeys("{ENTER}")
                print "pressing F11 to go for fullscreen - it is a presentation ;)"
                window.TypeKeys("{F11}")
                print "yay, we are done :)"
                break;
            except:
                print "Oh, no, an Exception, (something went wrong):"
                e = sys.exc_info()[0]

                print e
                time.sleep(1)

                print "will now retry_________________________________________"

print "build presentation object"
p = Presentation()    

print "start presentation"
p.start()

Vasily -是的，现在它会打印一些错误
