Python-具有CheckBox的Gtk.TreeView

Question

我需要將項目存儲在Gtk TreeView中，並且與此TreeView進行交互時，用戶可以在列表中選擇一個或多個項目。

因為我是GTK的新手，所以設法填充了樹形視圖並顯示了一個復選框，如下面的代碼所示。 但是，當我嘗試選擇時，什么也沒有發生，而且我不知道如何實現這一點。

這是我的代碼：

# 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. 如果您要選擇整行並發生某些情況：

    #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. 如果您想要在單擊切換開關時發生某些事情，請執行以下操作：

    #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
