python - 使用 CellRendererToggle 创建 Gtk3 TreeView ，并使用 Python 从列表中创建名称

Question

我尝试使用列表中的标题名称创建一个 Gtk.TreeView 。因为我想稍后用它来显示来自不同数据库的条目。

问题:当我单击一个单元格并尝试激活它时，该行中的所有单元格都会被激活。更奇怪的是，只有当我将光标移到它们上面(而不是单击)时，它们看起来才被激活。

这段代码有什么问题？

class CellRendererToggleWindow(Gtk.Window):

    def __init__(self):
        Gtk.Window.__init__(self, title="CellRendererToggle Example")
        self.set_default_size(400, 200)
        self.mainbox = Gtk.Box(orientation=Gtk.Orientation.HORIZONTAL, spacing = 10)
        self.add(self.mainbox)

        self.myliststore = Gtk.ListStore(bool,bool,str)
        self.treeview = Gtk.TreeView(self.myliststore)

        for n, header_text in enumerate(["Aktive", "Warning", "Text"]):
            if header_text in ["Aktive", "Warning"]:
                cell = Gtk.CellRendererToggle()
                cell.connect("toggled", self.on_sync_treeview_button_toggled, n, header_text )
                column = Gtk.TreeViewColumn(header_text, cell)
            else:
                cell = Gtk.CellRendererText()
                cell.set_property('editable', True)
                column = Gtk.TreeViewColumn(header_text, cell, text=n)
            column.set_sort_column_id(n)
            self.treeview.append_column(column)
        self.myliststore.append([True, True, "Super6!"])
        self.myliststore.append([True, True, "Super7!"])
        self.myliststore.append([True, True, "Super8!"])
        self.mainbox.pack_start(self.treeview, True, True, 0)

    def on_sync_treeview_button_toggled(self, widget, path, column, data):
        widget.set_active( [True,False][widget.get_active()] )


win = CellRendererToggleWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()

TreeViewColumn 需要一个“active”属性以及在商店中的位置:

column.add_attribute(cell, "active", n)

而且我还必须更改底层存储而不是小部件:

self.myliststore[path][column] = not self.myliststore[path][column]

感谢这个例子: https://github.com/Programmica/python-gtk3-tutorial/blob/master/_examples/cellrenderertoggle.py

现在它正在工作:
