Python空闲设置屏幕清除快捷方式,pythonIDLE,清屏


1、在python安装文件夹Lib中找到idlelib文件夹;

2、在此文件夹中新建CleanWindow.py文件,并输入以下代码:

class ClearWindow:

    menudefs = [

        ('options', [None,

               ('Clear Shell Window', '<<clear-window>>'),

       ]),]



    def __init__(self, editwin):

        self.editwin = editwin

        self.text = self.editwin.text

        self.text.bind("<<clear-window>>", self.clear_window)

    def clear_window2(self, event): # Alternative method

        # work around the ModifiedUndoDelegator

        text = self.text

        text.mark_set("iomark2", "iomark")

        text.mark_set("iomark", 1.0)

        text.delete(1.0, "iomark2 linestart")

        text.mark_set("iomark", "iomark2")

        text.mark_unset("iomark2")

        if self.text.compare('insert', '<', 'iomark'):

            self.text.mark_set('insert', 'end-1c')

        self.editwin.set_line_and_column()

    def clear_window(self, event):

        # remove undo delegator

        undo = self.editwin.undo

        self.editwin.per.removefilter(undo)

        # clear the window, but preserve current command

        self.text.delete(1.0, "iomark linestart")

        if self.text.compare('insert', '<', 'iomark'):

            self.text.mark_set('insert', 'end-1c')

        self.editwin.set_line_and_column()



        # restore undo delegator

        self.editwin.per.insertfilter(undo)

3、在本文件夹中,找到config-extension.def文件,用记事本打开,在文件末尾加入以下配置:

[ClearWindow]
enable=1
enable_editor=0
enable_shell=1
[ClearWindow_cfgBindings]
clear-window=<Control-Key-l>

4、重启IDLE,在菜单栏的Options中即可看到Clear Shell Window(Ctrl + L)

5、使用快捷键Ctrl + L,即可完成清屏操作
