Python Tkinter 旋转窗口，向右转

Question

有人用 Python 写了一个非常简单的“绘画”程序，我想稍微修改一下。我的一些问题是。如何对这个程序实现旋转功能？我希望能够将显示程序的窗口向右旋转 90 度。这可能吗？是否也可以实现从窗口中删除边框的功能。 (我说的是 gui 窗口)。

from Tkinter import *

"""paint.py: not exactly a paint program.. just a smooth line drawing demo."""

b1 = "up"
xold, yold = None, None

def main():
    root = Tk()
    drawing_area = Canvas(root)
    drawing_area.pack()
    drawing_area.bind("<Motion>", motion)
    drawing_area.bind("<ButtonPress-1>", b1down)
    drawing_area.bind("<ButtonRelease-1>", b1up)
    root.mainloop()

def b1down(event):
    global b1
    b1 = "down"           # you only want to draw when the button is down
                          # because "Motion" events happen -all the time-

def b1up(event):
    global b1, xold, yold
    b1 = "up"
    xold = None           # reset the line when you let go of the button
    yold = None

def motion(event):
    if b1 == "down":
        global xold, yold
        if xold is not None and yold is not None:
            event.widget.create_line(xold,yold,event.x,event.y,smooth=TRUE)
                          # here's where you draw it. smooth. neat.
        xold = event.x
        yold = event.y

if __name__ == "__main__":
    main()

解决方案是在 Linux 中旋转屏幕。我设法用命令做到了这一点:

xrandr --output HDMI1 --rotate right
