Python GUI 之Tkinter小结

from tkinter import *
# 一般在测量 tkinter 控件内的大小时，是以像素为单位。下面定义 Button 控件的文字与边框之间的水平距离为 20 像素：
win=Tk()
Button(win,padx=20,text="关闭",command=win.quit).pack()
win.mainloop()
from tkinter import *
# 也可以使用其他测量单位，如 c（厘米）、m（毫米）、i（英寸=2.54cm）、p（点，1p = 1 / 72英寸）。示例代码如下所示：
win=Tk()
Button(win,padx=20,text="关闭",command=win.quit).pack()
Button(win,padx="2c",text="关闭",command=win.quit).pack()
Button(win,padx="8m",text="关闭",command=win.quit).pack()
Button(win,padx="2i",text="关闭",command=win.quit).pack()
Button(win,padx="20p",text="关闭",command=win.quit).pack()
win.mainloop()
