双击检索树视图数据

Question

我正在尝试通过双击（row-activated 信号）检索 treeview 数据。我现在已经通过 changed 信号做到了这一点：

self.view.get_selection().connect("changed", self.row_activated)
def row_activated(self, selection):
    (model, iter) = selection.get_selected()
    print(model[iter][:])
    return True

但我无法使用 row-activated:

self.view.connect("row-activated", self.row_activated)
def row_activated(self):
    (model, iter) = self.view.get_selected()
    print(model[iter][:])
    return True

但是，这是错误的：

TypeError: row_activated() takes 1 positional argument but 4 were given

Answer 1

回答我自己的问题很奇怪，但我设法解决了它：

self.view.connect("row-activated", self.row_activated)
def row_activated(self, widget, row, col):
    model = widget.get_model()
    print(model[row][:])
    return True
