调试了很久，只能显示如此程度

中间的代码框和右侧的HTML显示框显示有问题

注释掉 rest_editor_view.py 中的

self.code_widget.code.keyPressEvent_action = self.keyPressEvent_action

可以显示如图的界面

try:

    self.code_widget.code.keyPressEvent_action = self.keyPressEvent_action

except:

    ....

or

if self.code_widget:

    self.code_widget.code.keyPressEvent_action = self.keyPressEvent_action

中间的代码框还是图上显示的那样，只有一行，不正常

你可以根据错误信息提示，在出错的地方加上判断。

都像第一个一样加了，不报错，但还是无法编辑只有一行

root@rosickey:/home/rosickey/Rsted/enthought/rst# python app.py
The rest editor only supports qt4 as toolkit. Toolkit changed to qt4.
/usr/lib/python2.6/dist-packages/enthought/etsconfig/etsconfig.py:343: UserWarning: Environment variable "HOME" not set, setting home directory to /tmp
  (environment_variable, parent_directory))

提示这个错误的话，应该是需要指定qt4为后台界面库吧。在app.py中添加：

import os

os.envion['ETS_TOOLKIT'] = 'qt4'

恩，已经添加了。

显示还是一行，无法编辑

root@rosickey:/home/rosickey/Rsted/enthought/rst# python app.py
/usr/lib/python2.6/dist-packages/enthought/etsconfig/etsconfig.py:370: UserWarning: Environment variable "HOME" not set, setting home directory to /tmp
  (environment_variable, parent_directory))
code widget Non

那个编辑器应该是用CodeEditor生成的，你可以先单独写一个测试程序看看它能否正常工作。

修改了rest_editor_view.py的458行

加了个height值，源码框是变大了，但是能编辑的地方还是一行...

        return View(Group(Group(Item('object.model.rest',
                                     style='custom',
                                     height = 600,

我想因为这个rest实际使用的编辑器应该是一个单行的文本框。所以你可以试试其他的editor。例如把editor=rest_editor删除试试看，或者单独写一个程序测试那个CodeEditor。或者看看traits的例子中的CodeEditor能否正常工作。或者从例子中找出一个能够进行多行编辑的编辑器。

谢谢了，果然这样。

删掉editor=rest_editor就可以了

        return View(Group(Group(Item('object.model.rest',
                                     style='custom',
                                     ),

...

为什么删除了就是多行了

不指定editor，就用Str对应的缺省的custom编辑器，这个编辑器就是多行的。这也就是说CodeEditor在Qt4下无法正常工作。也许要升级一下TraitsUI

恩，这样就少了一些行号，颜色之类的

  中文路径有有乱码

File "/home/rosickey/Rsted/enthought/rst/file_tree.py", line 51, in _get_children
    names = [str(f) for f in os.listdir(self.path)]
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

改成

        for f in os.listdir(self.path):
            if isinstance(f,unicode):
                names.append(str(f.encode("gb2312")))
            else:
                names.append(str(f.decode('utf-8').encode('gb2312')))
 会出现下边的错

  File "/usr/lib/python2.6/dist-packages/enthought/traits/has_traits.py", line 1279, in decorator
    self.__dict__[ name ] = result = function( self )
  File "/home/rosickey/Rsted/enthought/rst/file_tree.py", line 61, in _get_children
    path = os.path.join(self.path, fn)
  File "/usr/lib/python2.6/posixpath.py", line 70, in join
    path += '/' + b
UnicodeDecodeError: 'ascii' codec can't decode byte 0xbd in position 1: ordinal not in range(128)

这个地方字符编码怎么改呢

哲思，刚才修改的没显示。

self.path也是str

selfpathtthththth /home/rosickey/下载 <type 'str'>
selfpathtthththth /home/rosickey/EnthoughtBase <type 'str'>
selfpathtthththth /home/rosickey/mouse <type 'str'>
selfpathtthththth /home/rosickey/视频 <type 'str'>

显示了每个f的type何内容

        for f in os.listdir(self.path):
            print  'typessssssssssssssss',type(f)
            print f

结果type都已经是str了。下边有一句

names.sort(key=str.lower)排序

有中文就会报错type不对，但是之前的f类型已经是str了的

print 输出中文也正常。

～～～～～～～～～～～～～～

试着直接names = [(f) for f in os.listdir(self.path)]这样了，

注释掉了排序 names.sort(key=str.lower)

刚打开界面还是中文路径乱码，手动选择路径之后就正常了，不知到怎么个意思

点击乱码中文的节点，显示

中文目录果然乱码。我的编辑功能功能倒是很正常。（ubuntu10.10 & python2.6）

楼主现在还在用这个编辑器吗，可以交流一下？

在用，（ubuntu10.10 & python2.6） me too。。。
