如何在Glade预先创建的列表框中设置listStore模型? [英] How do I set a listStore model on pre-created listbox from Glade?

问题描述

显然，在 GTKListBox中包含项目的正确"方式或Treeview 在构造函数中使用listStore模型进行构造.如果我想使用已经在其中创建列表框并由builder.get_object("appsDocumentListBox")引用的列表框的Glade GUI项目怎么办?

Apparently the "proper" way to have items in a GTKListBox or Treeview is constructing with a listStore model, in the constructor. What if I want to use Glade GUI project, in which a list box is already created, and referenced by builder.get_object("appsDocumentListBox")?

我可以在Gtk.builder创建窗口之后设置模型，还是有更好的方法呢?

Can I set the model after Gtk.builder created the window, or is there a better way to do this?

我还想知道与使用row = Gtk.ListBoxRow()手动添加，添加内容并设置ListBox.add(row)相比，使用ListStore可以提高性能吗? (在Glade-builder Python窗口中有效)

I'm also wondering what the performance improvement is of using the ListStore vs manually adding with row = Gtk.ListBoxRow(), adding contents and setting ListBox.add(row)? (which does work from a Glade-builder Python window)

与Treeview不同，显然Listbox不会在构造函数之后设置模型?

Unlike Treeview, apparently Listbox won't set a model after constructor?

>>> l = Gtk.ListBox()
>>> l.set_model
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'ListBox' object has no attribute 'set_model'

推荐答案

您正在混淆两件事.您可以创建一个GtkListBox并向其中添加GtkListBoxRow.这里不需要额外的模型.

You are mixing two things up. You can create a GtkListBox and add GtkListBoxRows to it. There is no need for an extra model here.

还有GtkListStore和GtkTreeStore.他们两个都使用GtkTreeView. ListStore具有平坦的层次结构，并且TreeStore可以嵌套. GtkTreeView具有set_model函数，因此您可以在创建模型后对其进行设置.您也可以直接在Glade中创建相应的模型.

There are also GtkListStore and GtkTreeStore. Both of them use a GtkTreeView. The ListStore has a flat hierarchy and the TreeStore can be nested. The GtkTreeView has a set_model function so you can set a model after you created it. You can also create the corresponding model directly in Glade.

如果您要添加复杂的窗口小部件，则GtkListBox更适合.对于应该被排序或分层结构的大量数据，我宁愿使用GtkTreeView和相应的模型.

If you have complicated widgets that you want to add, the GtkListBox is better suited. For a lot of data which is supposed to be sorted or hierarchically structured, I would rather use a GtkTreeView with a corresponding model.
