是否可以在 Tkinter 中按名称搜索小部件? [英] Is it possible to search widget by name in Tkinter?

问题描述

如果我在 Tkinter 中创建一个小部件，我可以指定一个参与 tcl/tk小部件路径"概念的小部件名称.例如:

from Tkinter import *button = Button( Frame( Tk(), name = "myframe" ), name = "mybutton" )str( button ) == ".myframe.mybutton"

是否可以通过它的名称获取小部件，在我的示例中为mybutton"?

解决方案

是的，但是您必须持有对根Tk"实例的引用:只需使用Tk.nametowidget"方法:

<预><代码>>>>从 Tkinter 导入 *>>>赢 = Tk()>>>button = Button( Frame( win, name = "myframe" ), name = "mybutton" )>>>win.nametwidget("myframe.mybutton")<Tkinter.Button 实例在 0x2550c68>

If i create a widget in Tkinter i can specify a widget name that takes part in tcl/tk "widget path" concept. For example:

from Tkinter import *
button = Button( Frame( Tk(), name = "myframe" ), name = "mybutton" )
str( button ) == ".myframe.mybutton"

Is it possible to get a widget by it's name, "mybutton" in my example?

解决方案

Yes, but you have to hold a reference to the root "Tk" instance: just use the "Tk.nametowidget" method:

>>> from Tkinter import *
>>> win = Tk()
>>> button = Button( Frame( win, name = "myframe" ), name = "mybutton" )
>>> win.nametowidget("myframe.mybutton")
<Tkinter.Button instance at 0x2550c68>
