Question

我在用Glade创建的gtk-builder文件中定义了一个窗口。它包含gtk.Window，其中包含gtk.TreeView个子gtk.TreeViewColumn个<?xml version="1.0" encoding="UTF-8"?> <interface> <requires lib="gtk+" version="2.20"/>  <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> <property name="can_focus">True</property> <property name="hscrollbar_policy">never</property> <property name="vscrollbar_policy">automatic</property> <child> <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>：

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()

我正在创建窗口：

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

这只会显示“文字”栏：

gtk.TreeViewColumn

如果我改变了接口文件中<child> <object class="GtkTreeViewColumn" id="line_column">...</object> </child> <child> <object class="GtkTreeViewColumn" id="text_column">...</object> </child>的顺序：

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

为：

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

仅显示“Line”列：

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

但我希望它看起来像：

gtk.TreeViewColumn

更改接口文件中{{1}}的顺序正在改变显示的列，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视了什么？任何帮助将不胜感激。

Answer 1

您将列大小调整模式设置为“fixed”（我假设您出于性能原因需要这个），但不设置fixed-width属性。将它设置为两列上的任何值，它们将出现。

第一个TreeViewColumn没有渲染
