使用笔记本在 Tkinter GUI 中制作标签

Question

I am trying to make a GUI in Tkinter, want the GUI to have 2 tabs. I am using ttk.notebook for that.

My code is as follows:

root=tk.Tk()
root.title("Data Tool")
root.geometry("500x300")

nb = ttk.Notebook(root)

nb.place(relx=0,rely=0)

# Adds tab 1 of the notebook
page1 = ttk.Frame(nb)
nb.add(page1, text='Home')

# Adds tab 2 of the notebook
page2 = ttk.Frame(nb)
nb.add(page2, text='Tool')


tk.Label(page1,text="test",bg="red").place(relx=0.2,rely=0.4)

root.mainloop()

This GUI is not showing the label on page1. What could be wrong in the code?

Answer 1

Your label's master is set to page1 which is an empty frame, and then you call place on the label using relx and rely . To show the widget, your frame need to have a size:

page1 = ttk.Frame(nb,height=400,width=400)
