如何使用pywinauto从一个不可检测的控件[编辑]的应用程序中获取文本？

Question

我试图使用pywinauto自动化我的应用程序。我想从一个只能读取和聚焦的编辑框中读取值。是否有可能通过pywinauto？

这是我的代码：

dialog = Desktop(backend='uia')
win = dialog.window(title_re ="XXX_Decoder")
label=win.child_window(title="Debug Output",auto_id="debugConsoleGroupBox",control_type="Group")
label.child_window(auto_id="debugConsole", control_type="Edit").texts()

对于win.print_control_identifiers（）我得到：

Dialog - 'WRT BT Decoder'    (L52, T52, R724, B430)
['WRT BT Decoder', 'Dialog', 'WRT BT DecoderDialog']
child_window(title="WRT BT Decoder", auto_id="WRT_BT_Decoders", control_type="Window")
   | 
   | 
   | GroupBox - 'Debug Output'    (L80, T257, R670, B370)
   | ['Debug OutputGroupBox', 'GroupBox', 'Debug Output', 'GroupBox0', 'GroupBox1']
   | child_window(title="Debug Output", auto_id="debugConsoleGroupBox", control_type="Group")
   |    | 
   |    | Edit - ''    (L100, T276, R644, B364)
   |    | ['', 'Edit', '0', '1', 'Edit0', 'Edit1']
   |    | child_window(auto_id="debugConsole", control_type="Edit")
   |    |    | 
   |    |    | ScrollBar - 'Vertical'    (L625, T278, R642, B362)
   |    |    | ['ScrollBar', 'VerticalScrollBar', 'Vertical']
   |    |    | child_window(title="Vertical", auto_id="NonClientVerticalScrollBar", control_type="ScrollBar")
   |    |    |    | 
   |    |    |    | Button - 'Line up'    (L625, T278, R642, B295)
   |    |    |    | ['Line up', 'Line upButton', 'Button2']
   |    |    |    | child_window(title="Line up", auto_id="UpButton", control_type="Button")
   |    |    |    | 
   |    |    |    | Button - 'Line down'    (L625, T345, R642, B362)
   |    |    |    | ['Line downButton', 'Line down', 'Button3']
   |    |    |    | child_window(title="Line down", auto_id="DownButton", control_type="Button")
   | 

在inspect.exe中：

LegacyIAccessible.Name: ""
LegacyIAccessible.Role: editable text (0x2A)
LegacyIAccessible.State:    read only,focusable (0x100040)

就是这样。我怎样才能获得价值？

Answer 1

这可能是这样的：

label.child_window(auto_id="debugConsole", control_type="Edit").iface_value.GetValue()

它将在未来版本中作为.get_value()方法添加。
