4. Example:

A. Create an app main portal Program

#-*-Coding: UTF-8-*-# handler # Name: module shell # purpose: main entry function of the application # Author: ankier # created: 28-10-2012 # copyright: (c) ankier 2012 # licence: <your licence> # kernel import wxfrom mainframe import mainframeimport sys ##@ detail shellapp core class shellapp (wx.

B. Use of the mainframe file selection dialog box
