Python - Gtk.TreeView与复选框

Question

我需要在Gtk TreeView中存储一些项目，当用户与这个TreeView互动时，可以选择列表中的一个或多个项目。

因为我刚接触GTK，所以我成功地填充了TreeView，并显示了一个复选框，代码如下所示。但当我尝试选择时，什么也没有发生，我不知道该怎么做才能实现这个功能。

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让某些事情发生：

   #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. 如果你想在点击切换按钮时让某些事情发生：

   #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
