About

This is unit which contains the class to control the progressbar over the Windows 7+ taskbar button. The demo looks like this:

Taskbar button can be colored in several ways:

• none (inactive)
• green progress
• yellow progress (looks like paused state)
• red progress (looks like error state)
• marquee floating animation (progress value is ignored, it's constantly changing animation from min to max)
