What are the consequences when omitting the parent master of a widget? Those two programs do not produce a visual difference:
import tkinter as t
import tkinter.ttk as ttk
w = t.Tk()
w.title("Label 1")
label_1 = ttk.Label(text="Label")
label_1.grid(row=0, column=0)
fenster.mainloop()
vs.
import tkinter as t
import tkinter.ttk as ttk
w = t.Tk()
w.title("Label 1")
label_1 = ttk.Label(w, text="Label")
label_1.grid(row=0, column=0)
fenster.mainloop()
CodePudding user response:
When you ommit the master option it will use the root widget.
Which is the Tk() instance or in Tkinter the root widget '.'
You can get parent with winfo_parent() methode.
import tkinter as t
import tkinter.ttk as ttk
w = t.Tk()
w.title("Label 1")
label_1 = ttk.Label(text="Label")
label_1.grid(row=0, column=0)
print("parent =", label_1.winfo_parent())
w.mainloop()
Output:
parent = .
