使用复选框创建树视图 [英] Creating a Treeview with Checkboxes

问题描述

我正在尝试基于以下使用示例(如何在 Python 中创建带有复选框的树视图).

I am trying to build an application based on the following usage example (How to create a tree view with checkboxes in Python).

此示例使用 Tix 库构建带有复选框的 Treeview.However, when I run this example, whenever a Checkbox is checked, the text label of that box disappears.

This example builds a Treeview with checkboxes using the Tix library. However, when I run this example, whenever a Checkbox is checked, the text label of that box disappears.

有人能帮我避免上面提到的行为吗?

Could someone help me to avoid the behaviour mentioned just above?

import Tix

class View(object):
    def __init__(self, root):
        self.root = root
        self.makeCheckList()

    def makeCheckList(self):
        self.cl = Tix.CheckList(self.root, browsecmd=self.selectItem)
        self.cl.pack()
        self.cl.hlist.add("CL1", text="checklist1")
        self.cl.hlist.add("CL1.Item1", text="subitem1")
        self.cl.hlist.add("CL2", text="checklist2")
        self.cl.hlist.add("CL2.Item1", text="subitem1")
        self.cl.setstatus("CL2", "on")
        self.cl.setstatus("CL2.Item1", "on")
        self.cl.setstatus("CL1", "off")
        self.cl.setstatus("CL1.Item1", "off")
        self.cl.autosetmode()

    def selectItem(self, item):
        print item, self.cl.getstatus(item)

def main():
    root = Tix.Tk()
    view = View(root)
    root.update()
    root.mainloop()

if __name__ == '__main__':
    main()

推荐答案

问题是选择的默认前景色与背景色相同.问题通过在self.cl初始化后添加如下代码行解决:

The problem is that the default foreground color on selection is the same as the background color. The problem is resolved by adding the following line of code after the initialization of self.cl:

self.cl.hlist.config(selectforeground="black")
