Introduction

This example requires :

Be aware that:

This example will run a simple ProgressBar Monitor, with a function user callback. Its starts in indeterminate mode then switch back in determinate mode.

Color scheme came from a UI pre-set model (class) called Progress_ITDynamic, defined on lines 14 to 25.

The user callback defined on lines 27 to 47, and attached on progress bar at line 54, will run progress bar until its reached 60 then switch back to determinate mode to complete process. All 10%, we will echo result on monitor.

QF renderer rules are defined on lines 91 to 103.
