我在 Glade 制作的 gtk-builder 文件中定义了一个窗口。它包含一个, 和一个2 sgtk.Window的孩子：gtk.TreeViewgtk.TreeViewColumn

<?xml version="1.0" encoding="UTF-8"?>
<interface>
    <requires lib="gtk+" version="2.20"/>
    <!-- interface-naming-policy project-wide -->
    <object class="GtkWindow" id="bookmarks_window">
        <property name="can_focus">False</property>
        <property name="events">GDK_KEY_PRESS_MASK | GDK_STRUCTURE_MASK</property>
        <property name="title" translatable="yes">Bookmarks</property>
        <property name="modal">True</property>
        <property name="default_width">350</property>
        <property name="default_height">200</property>
        <property name="destroy_with_parent">True</property>
        <property name="type_hint">menu</property>
        <property name="skip_taskbar_hint">True</property>
        <child>
          <object class="GtkScrolledWindow" id="bookmarks_scroll">
            <property name="visible">True</property>

              <object class="GtkTreeView" id="bookmarks_tree">
                <property name="visible">True</property>
                <property name="can_focus">True</property>
                <property name="events">GDK_BUTTON_PRESS_MASK | GDK_KEY_PRESS_MASK | GDK_STRUCTURE_MASK</property>
                <property name="headers_visible">False</property>
                <property name="headers_clickable">False</property>
                <property name="rules_hint">True</property>
                <property name="fixed_height_mode">True</property>
                <property name="show_expanders">False</property>
                <property name="enable_grid_lines">vertical</property>
                <child>
                  <object class="GtkTreeViewColumn" id="line_column">
                    <property name="sizing">fixed</property>
                    <property name="title" translatable="yes">Line</property>
                  </object>
                </child>
                <child>
                  <object class="GtkTreeViewColumn" id="text_column">
                    <property name="sizing">fixed</property>
                    <property name="title" translatable="yes">Text</property>
                  </object>
                </child>
              </object>
            </child>
          </object>
        </child>
    </object>
</interface>

我正在创建窗口：

def show_window(parent_window):
    builder = gtk.Builder()
    builder.add_from_file("mywindow.ui")

    window = builder.get_object('bookmarks_window')
    window.set_transient_for(parent_window)

    tree = builder.get_object('bookmarks_tree')
    tree.set_search_column(1)

    store = gtk.TreeStore(int, str)
    for i in xrange(1, 6):
        store.append((i, "Line {}".format(i)))
    tree.set_model(store)

    line_renderer = gtk.CellRendererText()
    line_column = builder.get_object('line_column')
    line_column.pack_start(line_renderer)
    line_column.set_attributes(line_renderer, text=0)

    text_renderer = gtk.CellRendererText()
    text_column = builder.get_object('text_column')
    text_column.pack_start(text_renderer)
    text_column.set_attributes(text_renderer, text=1)

    window.show_all()

这将只显示“文本”列：

+---------------+
| Line 1        |
| Line 2        |
| Line 3        |
| Line 4        |
| Line 5        |
+---------------+

如果我将gtk.TreeViewColumn接口文件中 s 的顺序更改为：

<child>
  <object class="GtkTreeViewColumn" id="line_column">...</object>
</child>
<child>
  <object class="GtkTreeViewColumn" id="text_column">...</object>
</child>

到：

<child>
  <object class="GtkTreeViewColumn" id="text_column">...</object>
</child>
<child>
  <object class="GtkTreeViewColumn" id="line_column">...</object>
</child>

只有“行”列会显示：

+---------------+
| 1             |
| 2             |
| 3             |
| 4             |
| 5             |
+---------------+

但我希望它看起来像：

+---+-----------+
| 1 | Line 1    |
| 2 | Line 2    |
| 3 | Line 3    |
| 4 | Line 4    |
| 5 | Line 5    |
+---+-----------+

更改接口文件中 s 的顺序gtk.TreeViewColumn正在更改显示的列，这对我来说没有意义。它总是隐藏第一列。有谁知道我错过或忽略了什么？任何帮助，将不胜感激。

您将列大小模式设置为“固定”（我假设您出于性能原因需要此），但不要设置fixed-width属性。将其设置为两列上的任何值，它们就会出现。
