如何将“隐藏数据”分配给Gtk.TreeView行，以便使用Gtk.TreeView.connect（“row-activated”）捕获它们？

您可以只向列表库添加数据，而无需在树视图中显示数据。 以下代码片段显示了必要的更改：

...
def onRowChange(widget, row, col):
    # This function is executed when a user click on a row
    model = widget.get_model()
    iter_ = model.get_iter(row)
    person = model.get_value(iter_, 2)
    print(person.country)


class GridWindow(Gtk.Window):

    def __init__(self):
        Gtk.Window.__init__(self, title="TreeView MWE")
        self.connect("destroy", Gtk.main_quit)

        # Setting up the self.grid in which the elements are to be positionned
        self.grid = Gtk.Grid()
        self.grid.set_column_homogeneous(True)
        self.grid.set_row_homogeneous(True)
        self.add(self.grid)

        # Preparing the list store
        listStore=Gtk.ListStore(str, str, object)
        for aPerson in personsList:
            listStore.append([aPerson.firstName, aPerson.lastName, aPerson])
...

请尝试以下示例。一些原始代码被注释掉，下面是用 #*** 突出显示的替换代码。

单击一行时，控制台应显示一个包含三个字段（名字、姓氏和国家/地区）的列表。
