pywinauto.findwindows.ElementNotFoundError: 또는  AttributeError: WindowSpecification class has no 'SetFocus' method 에러 대응

pyWinauto를 이용하여 어플리케이션 프로그램의 자동화를 하고자 하는 경우

해당 커서를 텍스트에디터 항목에 위치시키고자 'SetFocus'를 사용하는 경우 위 에러 메시지가 발생하거나

ElementNotFoundError: 가 나는 경우

거의 2주동안 이방법 저방법 삽질하고 방법을 못찾다가 의외의 곳에서 해결하였다.

결국은 set_focus에서 문제가 발생한 것은 아니었다.

app = application.Application()
app.start('C:/CREON/STARTER/coStarter.exe')
title = "CREON Starter"
dlg = timings.WaitUntilPasses(20, 0.5, lambda: app.connect(title=title)).Dialog
pass_ctrl = dlg.Edit2
time.sleep(10)
pass_ctrl.set_focus()
pass_ctrl.type_keys("ID")
cert_ctrl = dlg.Edit3
cert_ctrl.SetFocus()
cert_ctrl.TypeKeys("PWD")
btn_ctrl = dlg.Button0
btn_ctrl.Click()

dlg = timings.WaitUntilPasses(20, 0.5, lambda: app.connect(title=title)).Dialog

이부분의 수정을 통해서 문제 해결

app.window_(title=title)) ==> app.connect(title=title).Dialog
