Tkinter.grid spacing options?
提问by PlatypusVenom
I'm new to Tkinter, and I tried creating an app with the grid layout manager. However, I can't seem to find a way to utilize it the way I want to. What I need to do is simulate a grid full of 'cells' so that I can place, for example, a label in cell (3,8) or a button in cell (5,1). Here is an example of what I've tried:
我是 Tkinter 的新手，我尝试使用网格布局管理器创建一个应用程序。但是，我似乎无法找到一种以我想要的方式使用它的方法。我需要做的是模拟一个充满“单元格”的网格，以便我可以在单元格 (3,8) 中放置一个标签或在单元格 (5,1) 中放置一个按钮。这是我尝试过的示例：
import tkinter as tk
root = tk.Tk()
label = tk.Label(root, text = 'Label')
label.grid(column = 3, row = 8)
button = tk.Button(root, text = 'Button')
button.grid(column = 5, row = 1)
Tkinter keeps the relative position of each widget (i.e. buttonis above and to the right of label), but it ignores any space in between. I've searched a bit for this problem and found out about weight, but that doesn't seem to be what I'm looking for; I'd like something independent of the labeland button's layouts. Thanks for the help!
Tkinter 保持每个小部件的相对位置（即button在 的上方和右侧label），但它会忽略中间的任何空间。我对这个问题进行了一些搜索，发现了 about weight，但这似乎不是我要找的；我想要一些独立于labelandbutton的布局。谢谢您的帮助！

You can specify the spacing on columns/rows in the grid (including those that contain no widget) by running the grid_columnconfigureand grid_rowconfiguremethods on the parent of the widgets (in this case, the parent would be root).
您可以通过在小部件的父级上运行grid_columnconfigure和grid_rowconfigure方法（在这种情况下，父级为root）来指定网格中列/行的间距（包括那些不包含小部件的）。
For example, to set a minimum width for the 4th column, add the last line to your code:
例如，要设置第 4 列的最小宽度，请将最后一行添加到您的代码中：
import Tkinter as tk
root = tk.Tk()
label = tk.Label(root, text = 'Label')
label.grid(column = 3, row = 8)
button = tk.Button(root, text = 'Button')
button.grid(column = 5, row = 1)
root.grid_columnconfigure(4, minsize=100) # Here
If you want to set a minimum size for all of your columns and rows, you can iterate through them all using:
如果要为所有列和行设置最小大小，可以使用以下方法遍历它们：
col_count, row_count = root.grid_size()
for col in xrange(col_count):
root.grid_columnconfigure(col, minsize=20)
for row in xrange(row_count):
root.grid_rowconfigure(row, minsize=20)
EditInterestingly, effbot states:
编辑有趣的是，effbot状态：
minsize=Defines the minimum size for the row. Note that if a row is completely empty, it will not be displayed, even if this option is set.
minsize=定义行的最小大小。请注意，如果一行完全为空，即使设置了此选项，它也不会显示。
(italics mine) but it seems to work even for rows and columns that are empty, as far as I've tried.
（斜体我的）但它似乎甚至适用于空的行和列，据我尝试。
回答by Bryan Oakley
By default, a row is of height zero and a column is of width zero. So, rows and columns that don't have anything in them will be invisible and take up no space.
默认情况下，行的高度为零，列的宽度为零。因此，其中没有任何内容的行和列将不可见且不占用空间。
