Python - 带有复选框的 Gtk.TreeView

Question

我需要将项目存储在一个 Gtk TreeView 中，当与这个 TreeView 交互时，用户可以在列表中选择一个或多个项目。

因为我是 GTK 的新手，所以我设法填充树视图并显示一个复选框，如下面的代码所示。但是当我尝试选择时，什么也没有发生，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)

Answer 1

1. 如果你想选择整行并且发生了一些事情：

   #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
   

2. 如果你想在你点击切换按钮时发生一些事情：

   #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
