The following code fragment works OK. Question: why? #====================================== from Tkinter import * root=Tk()
lbl=Label(root,text='1').pack() def doIt(): lbl.config(bg="yellow") btn=Button(root,text="do", bg="cyan",command=doIt).pack() root.mainloop() #======================================= My question is: how is the instance lbl.config(...) recognized in the doIt callback fn when called from the main w/o an argument referencing lbl? -- View this message in context: http://old.nabble.com/A-Button-command-callback-question...-tp32080551p32080551.html Sent from the Python - tkinter-discuss mailing list archive at Nabble.com.
