如何在gtk.ScrolledWindow中的GtkTreeView中显示列标题？

Question

我有一个问题与Gtk.Treeviewindide a Gtk.ScrolledWindow.我有大量的数据,不适合我的普通窗口几何,所以我把我的Treeview放在一个ScrolledWindow,这似乎是正常的方式.这个解决方案的问题是,当我滚动时,我的列标题消失了.这种行为对我来说似乎有点好,因为它ScrolledWindow应该关心它里面的小部件.

那么,如何让我的树视图是滚动和第一行中总是显示栏标题？

我修改了basictreeview.py示例来表示我的问题:

#!/usr/bin/env python

# example basictreeview.py

import pygtk
pygtk.require('2.0')
import gtk

class BasicTreeViewExample:

    # close the window and quit
    def delete_event(self, widget, event, data=None):
        gtk.main_quit()
        return False

    def __init__(self):
        # Create a new window
        self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
        self.window.set_title("Basic TreeView Example")
        self.window.set_size_request(200, 200)
        self.window.connect("delete_event", self.delete_event)

        # create a TreeStore with one string column to use as the model
        self.liststore = gtk.ListStore(str)

        # we'll add some data now - 4 rows with 3 child rows each
        for i in range(10):
            self.liststore.append([str(i)])

        # create the TreeView using treestore
        self.treeview = gtk.TreeView(self.liststore)

        # create the TreeViewColumn to display the data
        self.tvcolumn = gtk.TreeViewColumn("Column-Name", gtk.CellRendererText(), text=0)

        # add tvcolumn to treeview
        self.treeview.append_column(self.tvcolumn)

        # make it searchable
        self.treeview.set_search_column(0)

        # Allow sorting on the column
        self.tvcolumn.set_sort_column_id(0)

        # Allow drag and drop reordering of rows
        self.treeview.set_reorderable(True)

        # Add Treeview to a ScrolledWindow
        self.scrolledwindow = gtk.ScrolledWindow(hadjustment=None, vadjustment=None)
        self.scrolledwindow.set_policy(gtk.POLICY_AUTOMATIC, gtk.POLICY_AUTOMATIC)
        self.scrolledwindow.add_with_viewport(self.treeview)

        self.window.add(self.scrolledwindow)

        self.window.show_all()

def main():
    gtk.main()

if __name__ == "__main__":
    tvexample = BasicTreeViewExample()
    main()

更改self.scrolledwindow.add_with_viewport到self.scrolledwindow.add,它会工作.从文档:

add_with_viewport()方法用于向滚动窗口添加没有本机滚动功能的窗口小部件(由子窗口指定).这是一个便利功能,相当于将子项添加到gtk.Viewport,然后将视口添加到滚动窗口.如果孩子有本机滚动(例如gtk.TextView,gtk.TreeView,gtk.Layout),请使用gtk.Container.add()而不是此方法.

gtk.TreeView"本地滚动"将列标题保持在顶部,但如果您将整个树视图窗口小部件放在gtk.Viewport第一个,则整个窗口小部件将滚动.
