ThlLEDArray displays a configurable array of LEDs/buttons. The component appearance can be adjusted in many ways. f.e.: LED width/height, LED shape, LED Color, number of rows/columns, BorderWidth, BevelWidth, BackgroundColor, BackgroundBitmap etc.

Some possible scenarios for using it:

display status information for items like running operations, open/closed doors etc. Since the number of colors/states for each LED is freely configurable each LED can represent as many states as you need.
use it as a progress bar
use it to simply display a running light to reflect the activity of some operation. You could even show scrolling text with it.
the entire array can write itself into a bitmap and read from a bitmap. This can be used for persistence or to archive status snapshots etc.
the array can also be used as a multistate toggle-button array
in the case of 1x1 pixel LEDs and zero spacing the array collapses to a bitmap-like color field that can be used to display contour diagrams. Have a look at the screenshots in the help file and the demo application.

The component comes with demo project, prebuild demo exe, Html help and detailed installation instructions. Currently supported Borland products are Delphi 5/6/7/2005 and C++Builder 5/6.
