Question

通过使用类名，使用pywinauto函数从窗口中检索控件的值。最近，当尝试使用SAP时，这似乎是个问题，因为类名是动态的。有没有办法获取控件的动态类名，或者是否有使用控件ID而不是类名访问控件的方法。

from pywinauto.application import Application

app = Application().Connect(title=u'Create Purchase Order', class_name='SAP_FRONTEND_SESSION')
sapfrontendsession = app.SAP_FRONTEND_SESSION
print sapfrontendsession.PrintControlIdentifiers()

it gives

Control Identifiers:

控制需求是Afx：62F20000：8：00010003：00000010：00000000但是每次运行都会改变它。当用swapy检查时，controlID是相同的。有可能使用controlID可以检索此控件上的文本。

Answer 1

通常不保证控制ID是永久性的。我认为通过正则表达式匹配class_name会更可靠。

app.Dialog.child_window(class_name_re='^constant_part.*$').some_method()

# though Control ID can be used so
app.Dialog.child_window(control_id=0x5D).some_method()
# or
app.Dialog.child_window(class_name_re='^constant_part.*$', found_index=0).some_method()

同样适用于title_re。在您的特定情况下：

sapfrontednsession.child_window(title_re='^Standard PO created under the number \d+$').click()

可以使用MS Visual Studio中包含的Spy ++实用程序（可从“开始”菜单中获得）找到控件ID。

sapfrontednsession.child_window(control_id=<found ID in hex>).click()

Answer 2

通过我对这个主题的研究，听起来像从afx控件获取文本是非常复杂的，因为这个文本直接绘制到屏幕（它是一个图像），不像其他，例如“静态”控件。

我想说最好的办法是使用MSAA或UI Automation框架从主窗口浏览应用程序的UI结构。

需要一种方法来使用pywinauto在具有控制ID的窗口中访问控件
