/*
* This is an example program for use with the libsx library. This
* example shows how to implement a simple file requestor. The main
* window has two button widgets: a load button and a quit button. The load
* button will open a file requestor window where the user can select a
* file from a scrollable list. The program will block until the user
* has selected a file or cancelled the load at which point the appropriate
* action can be taken.
