How could I hide an existing Label when a button is clicked in Python(Tkinter)?

推荐答案

这实际上取决于您使用的几何管理器.如果您使用

This really depends on the geometry manager you used. If you use

lbl = Tkinter.Label(parent)

要创建标签，您将使用以下方法之一将其隐藏.

to create the label, you will use one of the following to hide it.

lbl.grid_forget()
lbl.pack_forget()
lbl.place_forget()

编辑(工作示例)

import tkinter

class MyClass(tkinter.Frame):
    def __init__(self,parent, *args, **kwargs):
        tkinter.Frame.__init__(self, parent, *args, **kwargs)

        self.btn = tkinter.Button(self,text='Don\'t push me',command=self.buttonCmd)
        self.btn.grid(row=0,column=0,sticky='nwes')
        self.lbl = tkinter.Label(self,text='Push it, it\'s fun')
        self.lbl.grid(row=0,column=1,sticky='nwes')

    def buttonCmd(self,*args,**kwargs):
        self.lbl.grid_forget()

root = tkinter.Tk()
MyFrame = MyClass(root)
MyFrame.pack(expand='true',fill='both')
root.mainloop()
