Python3.7.0 Shell新增清屏快捷鍵的實現示例

1、找到python的安裝目錄在python (版本號)\lib\idlelib目錄下

Python3.7.0 Shell新增清屏快捷鍵的實現示例

新增Clearwindow.py檔案

原始碼如下:

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_window2)
 
    self.text.bind("<<undo>>",self.undo_event) # add="+" doesn't work
 
  def undo_event(self,event):
    text = self.text
 
    text.mark_set("iomark2","iomark")
    text.mark_set("insert2","insert")
    self.editwin.undo.undo_event(event)
 
    # fix iomark and insert
    text.mark_set("iomark","iomark2")
    text.mark_set("insert","insert2")
    text.mark_unset("iomark2")
    text.mark_unset("insert2")
 
  def clear_window2(self,event): # Alternative method
    # work around the ModifiedUndoDelegator
    text = self.text
    text.undo_block_start()
    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")
    text.undo_block_stop()
    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','end-1c')
    self.editwin.set_line_and_column()
 
    # restore undo delegator
    self.editwin.per.insertfilter(undo)

2、繼續在當前目錄下(python (版本號)\lib\idlelib)開啟編輯config-extensions.def(IDLE擴充套件配置檔案)

在原檔案下新增如下程式碼:

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

3、重新啟動IDLE,點選Options,可看到:
