About

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

Win32TaskbarProgressDemo.png

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)
