LED Counter: A general purpose counter

LED Counter is a general purpose counter implemented as a Gnome Applet. It displays the counted number on an old fashion 7 segment or a 5x7 dots display. It can count mail messages or simple display the value written to stdout of any command, making it possible to count almost everything (e.g. to count currently logged in user: 'who|wc'). Displays and digits can be added and removed at any time.


The Counter uses two new GTK+ classes which are part of the distribution. The first class implements a single digit, either 7-segment or 5x7 dots and the second one implements a multi digit display. Since this is my first attempt to create a new GTK+ class it may not be perfect.


  • Counts unread/all mail messages
  • Displays the integer value written to stdout of a command.
  • Any number of counters with each up to 10 digits.
  • Update time, number of digits, colors, ... can be set by user.
  • Works in both orientations (restart required)
  • Fixed number of digits and autoranging
  • Shows overflow of counter
  • Allows to preset counter
  • Displays negative numbers

The most recent release of LED Counter is version 0.7.0.

To compile this you'll need to have gnome installed.


After pressing the command button under the display the applet stops working.
This is probably because you forgot to send the programm into the background. The counter will continue, when you quit the command. Put a & behind the command to execute.
Why does changing the number of counters has no effect?
Currently you will have to restart the applet to alter the number of counters.


  • Allow color selection for each display.
  • Run mail counting as thread.
  • Change orientation at runtime
