Accepted Answer

`pywinauto` requires 2-level hierarchy from Application object to control method. The structure of any call is ``` app...() ``` In your case it should look like ``` app.Dialog.About.click() ``` If you need more realistic click, please use `click_input()` which moves cursor and clicks the control as user. `click()` only sends `WM_CLICK` and it's less reliable also. `print_control_identifiers()` method prints the following information: ``` - '' () possible names which are most likely useful for object attribute access ``` Mentioned code is equivalent to the following: ``` app.window(best_match='Dialog', top_level_only=True).child_window(best_match='About').click() ``` `pywinauto` simplifies such constructions by overriding `__getattribute__` method.
