Python IDLE清屏
梦里逆天 人气:0实现步骤:
新建ClearWindow.py
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', '<', 'iomark'): self.text.mark_set('insert', 'end-1c') self.editwin.set_line_and_column() # restore undo delegator self.editwin.per.insertfilter(undo)
将ClearWindow.py复制到python安装目录下的Lib\idlelib目录(比如我的是:D:\Softwares\Python\Python310\Lib\idlelib)
修改idlelib目录下的config-extensions.def。修改之前最好先复制一份作为备份。
在文件末尾添加如下内容:
[ClearWindow] enable = True enable_editor = False enable_shell = True [ClearWindow_cfgBindings] clear-window = <Control-Key-l>
保存文件并关闭。
启动IDLE
点击"Options",会发现多了一个选项“Clear Shell Window”。
随便输入一些指令
按快捷键Ctrl+L(或者鼠标点击“Options”,选择“Clear Shell Window”。
再输入指令,发现能正常使用。
