/***************** Simple Scroll Panel Example ************************
 *This example uses three scroll panes. It is built on the Simple
 * Panel Example, so it has a 3 row, 1 column, Grid Layout for the frame.
 * Flow Layout is used within each of the rows by default, this is why
 * there is no code defining these.
