python添加清屏功能

创建文件ClearWindow添加内容

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)

2.在文件config-extensions.def中末尾添加

[ClearWindow]

enable=1

enable_editor=0

enable_shell=1

[ClearWindow_cfgBindings]

clear-window=<Control-Key-;>

3.重启idle
