画布和按钮的位置Python

Question

我试着做一些类似于图1的事情，但我不明白哪里出了问题。当我运行第一个代码时，它看起来像图2。有人能帮帮我吗？谢谢

import math
import Tkinter
import tkMessageBox
import Canvas



main = Tkinter.Tk()
main.geometry("1500x1000")
main.title("Momentum")
canvas = Tkinter.Canvas(main, width=1000, height =600)
canvas.grid(row=0,column=0)
box = canvas.create_rectangle(150,20,850,400)

ol1= Tkinter.Label(main, text="Object A")
ol2= Tkinter.Label(main,text="Object B")
ml1 = Tkinter.Label(main, text ="MASS")
ml2 = Tkinter.Label(main, text ="MASS")
me1 = Tkinter.Entry(main)
me2 = Tkinter.Entry(main)
ol1.grid(row=550, column=300)
ol2.grid(row=550, column=500)
ml1.grid(row=600, column =300 )
ml2.grid(row =600, column =500 )
me1.grid(row=620, column =300)
me2.grid(row=620, column=500)





main.mainloop()

使用行和列是非常直接的http://effbot.org/tkinterbook/grid.htm您应该发布您尝试过的其他内容以及为什么它不是您想要的。在

import Tkinter

main = Tkinter.Tk()
main.geometry("1500x1000")
main.title("Momentum")
canvas = Tkinter.Canvas(main, width=1000, height =600)
canvas.grid(row=0,column=1, columnspan=2)
box = canvas.create_rectangle(150,20,850,400)

ol1= Tkinter.Label(main, text="Object A")
ol2= Tkinter.Label(main,text="Object B")
ml1 = Tkinter.Label(main, text ="MASS")
ml2 = Tkinter.Label(main, text ="MASS")
me1 = Tkinter.Entry(main)
me2 = Tkinter.Entry(main)
ol1.grid(row=1, column=1)
ol2.grid(row=1, column=2)
ml1.grid(row=2, column =1 )
ml2.grid(row =2, column = 2)
me1.grid(row=3, column =1)
me2.grid(row=3, column=2)

main.mainloop()
