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)
 
        os.path.walk(self.dir,iter,self)
        self.sortedkeys = self.files.keys()
        self.sortedkeys.sort()
 
    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")
    else:
        appuifw.note(u"No file selected.", "info")
 
Main()
