Below is the code for class to select a file in a directory tree in PySymbian:

import os
class FileSelector:
def __init__(self,dir=".",ext='.jpg'):
self.dir = dir
self.ext = ext
self.files = {}
def iter(fileselector,dir,files):
for file in files:
b,e = os.path.splitext(file)
if e == fileselector.ext:
fileselector.files[u'%s' % b] = os.path.join(dir,file)
self.sortedkeys = self.files.keys()
def GetKeys(self):
return self.sortedkeys
def GetFile(self,index):
return self.files[self.sortedkeys[index]]

How to use this code

A simple example to select an image in a subdirectory:

import appuifw
import fileselector
def Main():
selector = FileSelector("e:\\images",".jpg")
index = appuifw.selection_list(selector.GetKeys())
if index is not None:
appuifw.note(u"File %s selected." % selector.GetFile(index), "info")
appuifw.note(u"No file selected.", "info")
