tkinter ttk 样式在 tkinter 中，我想让我的 label 出现

Question

I created new style frame using ttk.style And I made the frame appear with image. but a label doesn't appear on the frame.

Here is my code:

root = tk.Tk()
style = ttk.Style()
img = tk.PhotoImage(file="img/line_test.png")
style.element_create("teststyle.TFrame", "image", img)
style.configure("teststyle.TFrame", background="red", compound="center")
style.layout("teststyle.TFrame", [("teststyle.TFrame", {"sticky": "nsew"})])
frame = ttk.Frame(root, style="teststyle.TFrame", height=100, width=360)
test_lbl = ttk.Label(frame, text="test", style="teststyle.TFrame")
test_lbl.pack()
frame.pack()
root.mainloop()

You are trying to apply the style to both the frame and the label inside your frame. You should not be using the custom style for the label widget.

The problem is that the layout specifies which internal elements appear for the widget and how they are organized. A scrollbar has a trough and a thumb and a border. Buttons have text elements and borders, a Label has a border and a text element, etc. Your frame layout only has a border, it doesn't have a text element. Thus, any text associated with the widget won't show.

You need to remove the style from the label widget:

test_lbl = ttk.Label(frame, text="test")
