Question

我需要将项目存储在Gtk TreeView中，当与此TreeView交互时，用户可以选择列表中的一个或多个项目。

因为我是GTK的新手，所以我设法填充了树视图并显示了一个复选框，如下面的代码所示。但是当我尝试选择时，没有任何反应，我不知道如何做到这一点。

这是我的代码：

# the column is created
renderer_products = gtk.CellRendererText()
column_products = gtk.TreeViewColumn("Products", renderer_products, text=0)
# and it is appended to the treeview
view.append_column(column_products)

# the column checkbox is created
renderer_checkbox = gtk.CellRendererToggle()
column_checkbox = gtk.TreeViewColumn("Selected", renderer_checkbox, text=0)
# and it is appended to the treeview
view.append_column(column_checkbox)

如果您想选择整行并发生一些事情：

#double click or not double click use
Gtk.TreeView.set_activate_on_single_click (bool)
#connect the treeview
treeview.connect ("row-activated", on_row_activate)
#inside the callback
def on_row_activate (treeview, path, column):
    model = treeview.get_model ()
    iter  = treeview.get_iter (path)
    yourdata = model[iter][model_index]
    #do whatever with yourdata

如果您想在单击切换时想要发生某事：

#connect the renderer
renderer_checkbox.connect ("toggled", on_selected_toggled)
#inside the callback
def on_selected_toggled (renderer, path):
    #modify the model or get the value or whatever
