使用pyuno我打开一个LibreOffice calc文档,我定义了一系列单元格,我想对它进行排序。这是代码:

import os
import uno

# open a calc document
# (it is assumed that LibreOffice is launched with the command line:
# soffice -accept="socket,host=localhost,port=2002;urp")
local = uno.getComponentContext()
resolver = local.ServiceManager.createInstanceWithContext("com.sun.star.bridge.UnoUrlResolver", local)
context = resolver.resolve("uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext")
desktop = context.ServiceManager.createInstanceWithContext("com.sun.star.frame.Desktop", context)
url = uno.systemPathToFileUrl(os.path.abspath("c:/aaa/essai.xls"))
doc = desktop.loadComponentFromURL(url,"_blank", 0, ())

# range to be sorted
range = doc.Sheets.getByIndex(0).getCellRangeByPosition(0,0,4,4)
# use the first column for the sort key 
colDescr = uno.createUnoStruct(
  'com.sun.star.table.TableSortField')
colDescr.Field = 0 
# sort descriptor
sortDescr = range.createSortDescriptor()
for x in sortDescr: 
  if x.Name == 'SortFields':
    x.Value = (colDescr,)
    break
else:
  raise KeyError('SortFields')
# sort ...
range.sort(sortDescr)

此代码已正确解释但不执行任何操作(行未在calc文档中排序) 我错了吗?我认为sortDescr具有正确的类型(PropertyValue元组),但我不确定。 我使用Windows 7,LibreOffice 4.3.4.1,Python 3.3 谢谢你的回答。

答案 0 :(得分:1)

更改行: x.Value =(colDescr,)

通过: x.Value = uno.Any('[] com.sun.star.table.TableSortField',(aCriterios,))
