在窗口中定位画布 - Tkinter/python

Question

有没有办法在窗口中放置画布并在它周围放置一个框架？我只找到了如何在画布内定位对象。

Answer 1

You can create a frame, then put your widgets in it:

f = tk.Frame(...)
c1 = tk.Canvas(f, ...)
c2 = tk.Canvas(f, ...)
c1.pack(side="left", fill="both", expand=True)
c2.pack(side="right", fill="both", expand=True)

The above will give you two side-by-side canvases inside a single frame. They will grow and shrink as you resize the containing window.

Answer 2

You can use the place() function instead of pack() and do something like:

canvas.place(relx=0.5, rely=0.5, anchor=CENTER)

this would place it at the center.

Answer 3

Like fortyTwo102 mentioned, the place function will allow you to specify exactly where the canvas is. I thought I'd provide some more examples:

# in the center
canvas.place(relx=0.5, rely=0.5, anchor=CENTER)

# in the bottom right corner
canvas.place(relx=1.0, rely=1.0, anchor=SE)

# in the bottom left corner
canvas.place(relx=0.0, rely=1.0, anchor=SW)

# 30 pixels from the left, 50 from the top
canvas.place(x=30, y=50)
