python - 在 Python (Tkinter) 的同一窗口内混合两个布局管理器

Question

我是Python和Tkinter的新手，所以我希望这个问题对前辈来说很简单......

我有这个棋盘:

我正在使用网格布局管理，如下所示:

from tkinter import *

def checkerboard(can):
    w = can.winfo_width()
    h = can.winfo_height()
    cellwidth = w / 4
    cellheight = h / 4

    for row in range(4):
        for col in range(4):
            x1=col * cellwidth
            y1=row * cellheight
            x2=(col + 1) * cellwidth
            y2=(row + 1) * cellheight
            can.create_rectangle(col * cellwidth, row * cellheight, (col + 1) * cellwidth, (row + 1) * cellheight,
                                 fill='white')
            can.create_text(((x1+x2)/2,(y1+y2)/2),text='A')

window = Tk()
thecanvas = Canvas(window, width=500, height=500)
thecanvas.grid(row=0, column=0)
window.update_idletasks()
checkerboard(thecanvas)
window.mainloop()

问题是我想在棋盘上方添加一条不属于网格布局的前一行。像这样:

我怎样才能实现它？

提前致谢

你不使用 grid要创建检查板，您可以使用 grid仅将 Canvas 放在窗口中。

Canvas在row=0所以你可以把它放在row=2然后你可以把Labels在 row=0和 row=1

l1 = Label(window, text="I WANT TO CREATE THIS LABEL")
l1.grid(row=0, column=0)

l2 = Label(window, text="AND THIS TOO", fg='red')
l2.grid(row=1, column=0)

thecanvas = Canvas(window, width=500, height=500)
thecanvas.grid(row=2, column=0)

完整代码

from tkinter import *

def checkerboard(can):
    w = can.winfo_width()
    h = can.winfo_height()
    cellwidth = w / 4
    cellheight = h / 4

    for row in range(4):
        for col in range(4):
            x1=col * cellwidth
            y1=row * cellheight
            x2=(col + 1) * cellwidth
            y2=(row + 1) * cellheight
            can.create_rectangle(col * cellwidth, row * cellheight, (col + 1) * cellwidth, (row + 1) * cellheight,
                                     fill='white')
            can.create_text(((x1+x2)/2,(y1+y2)/2),text='A')

window = Tk()

l1 = Label(window, text="I WANT TO CREATE THIS LABEL")
l1.grid(row=0, column=0)

l2 = Label(window, text="AND THIS TOO", fg='red')
l2.grid(row=1, column=0)

thecanvas = Canvas(window, width=500, height=500)
thecanvas.grid(row=2, column=0)

window.update_idletasks()
checkerboard(thecanvas)
window.mainloop()

而不是 grid()你甚至可以使用 pack()你得到相同的结果

l1 = Label(window, text="I WANT TO CREATE THIS LABEL")
l1.pack()

l2 = Label(window, text="AND THIS TOO", fg='red')
l2.pack()

thecanvas = Canvas(window, width=500, height=500)
thecanvas.pack()

如果你真的需要混合管理器，那么你也可以输入 Frame在 row=0和 Canvas在 row=1然后你可以使用 pack()里面Frame

frame = Frame(window)
frame.grid(row=0, column=0)

l1 = Label(frame, text="I WANT TO CREATE THIS LABEL")
l1.pack()

l2 = Label(frame, text="AND THIS TOO", fg='red')
l2.pack()

thecanvas = Canvas(window, width=500, height=500)
thecanvas.grid(row=1, column=0)
