如何在python中放置文本框？

Question

Could you help me with positioning my textbox named "stuff" (If you have any good tutorials could you post those, too?).

import tkinter
from tkinter import font
from datetime import datetime

now = datetime.now()
month = now.month
day = now.day
year = now.year

stuff = "the month is %s the day is %d and they year is %s" % (month, day, 
year)

topwindow = tkinter.Tk()
textbox = tkinter.Text(topwindow)
textbox.configure(font=("Times New Roman", 50, "bold"))
textbox.insert( tkinter.INSERT, str(stuff))
textbox.pack()
topwindow.mainloop()

Answer 1

There are three ways to position widgets in tkinter. Tkinter has three geometry managers : pack , place , and grid which are used for placement.

pack operates on the concept of a box. you "pack" items to one of the sides of an empty box. It is best for when you need to place a single widget, or a group of widgets in a single row or a single column.

grid does as its name implies, it organizes widgets in a grid. Every widget is given a row and a column, and there are additional options for spanning rows and column, padding, etc.

place is the least used geometry manager. Its main advantage is it allows you to do absolute positioning. It also allows relative positioning (eg: you can place one widget in the exact middle of another). The downsize to using place is that you have to do a lot of the math yourself, and it's much harder to get widgets to behave properly when fonts or resolutions change, or the user changes the size of the window.

The advantage that grid and pack have over place is that they will automatically grow or shrink the window to fit its contents. This means that you don't much have to worry about the size of your GUI, it will become the size it needs to be. pack and grid are the best choice if you want your UI to be responsive -- to react properly when run on different systems with different resolutions or fonts, and for when the user resizes the window.

The tkinter book at effbot.org is one place that has some good basic documentation:

• The grid geometry manager
• The pack geometry manager
• The place geometry manager

It's important to note that you can use all three within the same application -- they all have strengths and weaknesses. The only caveat is that you can't use both grid and pack on different widgets that share the same parent (or master, depending on the terminology you prefer).

只需使用textbox.pack() ，如果您希望将其放置在左侧，请使用textbox.pack(side=LEFT) ，如果要放置在右侧，请使用textbox.pack(side=RIGHT)
