在Python（Tkinter）的同一窗口中混合两个布局管理器

Question

我对Python和Tkinter很陌生，所以我希望这个问题对老年人来说很容易......

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添加前一行，它不属于网格布局。像这样：

我怎样才能实现它？

您没有使用grid来创建核对，您只能使用grid将画布放在窗口中。

Canvas位于row=0，因此您可以将其放入row=2，然后您可以将Labels放入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()

您可以使用grid()代替pack()而获得相同的结果

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()

如果您真的需要混合经理，那么您也可以将Frame放在row=0和Canvas row=1中，然后在pack()内使用Frame { {1}}

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)

最佳解决方案是为棋盘创建一个框架，然后您可以在该框架中创建小部件。在主窗口中，您可以使用任何要添加棋盘格和任何其他窗口小部件的几何管理器。

尽管如此，在这种特定情况下，您只需将画布移动到第一行，然后在第0行添加任何其他内容。
