Python Tkinter网格复选框 [英] Python Tkinter Grid Checkbox

问题描述

我想知道是否有一种简单的方法可以使用Tkinter创建复选框网格。我试图制作一个包含10行和10列（所以100个复选框）的网格，以便每行只能选择两个复选框。

I was wondering if there is an easy way to create a grid of checkboxes using Tkinter. I am trying to make a grid of 10 rows and columns (so 100 checkboxes) so that only two checkboxes can be selected per row.

编辑：我正在使用python 2.7 with spyder

I'm using python 2.7 with spyder

到目前为止，我有：

from Tkinter import*

master = Tk()
master.title("Select Groups")

rows=10
columns=10


for x in range(rows):
    for y in range(columns):
        Label(master, text= "Group %s"%(y+1)).grid(row=0,column=y+1)
        Label(master, text= "Test %s"%(x+1)).grid(row=x+1,column=0)
        Checkbutton(master).grid(row=x+1, column=y+1)

mainloop()

我正在尝试使用state ='Disabled'将选中两个复选框的行显示为灰色。

I'm trying to use state='Disabled' to grey out a row once two checkboxes have been selected.

推荐答案

以下是使用您提供的10x10网格的示例。它应该为您提供有关如何实现此功能的基本思想。

Here's an example using your provided 10x10 grid. It should give you the basic idea of how to implement this.

只需确保对每个 Checkbutton （框）以及每个 IntVar （例子中的 boxVars ）。

Just make sure you keep a reference to every Checkbutton (boxes in the example) as well as every IntVar (boxVars in the example).

原因如下：

-检查按钮需要调用 config（状态=已禁用/正常）。

- IntVars 是需要确定每个 Checkbutton 的值。

-IntVars are needed to determine the value of each Checkbutton.

除了这些关键元素外，基本上只是一些2D数组处理。

Aside from those crucial elements its basically just some 2D array processing.

这是我的示例代码（现在基于您提供的代码）。

Here's my example code (now based off of your provided code).

from Tkinter import *

master = Tk()
master.title("Select Groups")

rows=10
columns=10

boxes = []
boxVars = []

# Create all IntVars, set to 0

for i in range(rows):
    boxVars.append([])
    for j in range(columns):
        boxVars[i].append(IntVar())
        boxVars[i][j].set(0)

def checkRow(i):
    global boxVars, boxes
    row = boxVars[i]
    deselected = []

    # Loop through row that was changed, check which items were not selected 
    # (so that we know which indeces to disable in the event that 2 have been selected)

    for j in range(len(row)):
        if row[j].get() == 0:
            deselected.append(j)

    # Check if enough buttons have been selected. If so, disable the deselected indeces,
    # Otherwise set all of them to active (in case we have previously disabled them).

    if len(deselected) == (len(row) - 2):
        for j in deselected:
            boxes[i][j].config(state = DISABLED)
    else:
        for item in boxes[i]:
            item.config(state = NORMAL)

def getSelected():
    selected = {}
    for i in range(len(boxVars)):
        temp = []
        for j in range(len(boxVars[i])):
            if boxVars[i][j].get() == 1:
                temp.append(j + 1)
        if len(temp) > 1:
            selected[i + 1] = temp
    print selected


for x in range(rows):
    boxes.append([])
    for y in range(columns):
        Label(master, text= "Group %s"%(y+1)).grid(row=0,column=y+1)
        Label(master, text= "Test %s"%(x+1)).grid(row=x+1,column=0)
        boxes[x].append(Checkbutton(master, variable = boxVars[x][y], command = lambda x = x: checkRow(x)))
        boxes[x][y].grid(row=x+1, column=y+1)

b = Button(master, text = "Get", command = getSelected, width = 10)
b.grid(row = 12, column = 11)
mainloop()
