诅咒.回声（）窗户成了垫子后，诅咒地停止了工作

Question

在这个程序的早期版本中，echo（）可以正常工作，但在一些重写之后停止工作。 我唯一能想到的是主窗口(自身屏幕)现在是一个垫子而不是stdscr。在

其他的一切都像以前一样工作；当我在一个选择上按enter键时，我可以输入一个字符串，当我输入时，字符串就在那里了。当我输入或粘贴时，它只是不回显它，直到getstr（）完成我才能看到它。我不明白为什么。在我看来，这一切都应该像echo（）/noecho（）一样简单。。在

是我漏掉了什么还是这是个虫子？在

（我知道这个代码与pep8不兼容。我最终会解决的）

在旧版本中工作！公司名称：

        if q == ord("\n"):
            if selection >= 0:
                target_value = values[selection][0]
                screen.timeout(-1)
                curs_set(1)
                curs_pos = values[selection][1]
                screen.move(curs_pos[0], curs_pos[1])

Answer 1

这只是我没有很好地阅读文档。在

A pad is like a window, except that it is not restricted by the screen size, and is not necessarily associated with a particular part of the screen. Pads can be used when a large window is needed, and only a part of the window will be on the screen at one time. Automatic refreshes of pads (such as from scrolling or echoing of input) do not occur. The refresh() and noutrefresh() methods of a pad require 6 arguments to specify the part of the pad to be displayed and the location on the screen to be used for the display.

只需在需要启用echo（）的部分中使用newwin（）而不是重写pad窗口，就解决了这个问题。在
