在IDLE中要實現清屏的功能,可透過以下步驟完成功能擴充套件:
一、下載https://bugs.python.org/file14116/ClearWindow.py複製程式碼儲存成為ClearWindow.py檔案
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)
二、將ClearWindow.py複製到Python安裝目錄下的Lib/idlelib中,如C:\Python\Python37\Lib\idlelib三、用記事本編輯config-extensions.def,在檔案末尾新增如下程式碼,啟用擴充套件。[ClearWindow]enable=1enable_editor=0enable_shell=1[ClearWindow_cfgBindings]clear-window=<Control-Key-w>
