Honeycombs

Honeycombs is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

The task is to produce a matrix of 20 hexagon shaped widgets in a honeycomb arrangement. The matrix should be arranged in such a manner that there are five columns of four hexagons. The hexagons in columns one, three and five are aligned horizontally, whereas the hexagons in columns two and four occupy a lower position within the arrangement. Each hexagon should be the same colour, and should display a unique randomly selected single capital letter on the front. The application should now wait for the user to select a hexagon, either by using a pointing device, or by pressing a key that carries a corresponding letter on a hexagon. The selected hexagon should now change colour on the display. A message should be now be output saying "The user chose letter E" (or whatever letter the user actually chose). The cycle repeats until the user has chosen five of the letters. Note that each letter can only be selected once and previously selected hexagons retain their colour after selection. The program terminates when all five letters have been chosen.
