The jcolrgb Colour Selection Panel

Introduction

The jcolrgb application is just a wrapper around the j:prompt_colour_rgb procedure in the jprompts.tcl library. It's intended to make it easy to ask the user to select a colour from shell scripts.

This document describes jcolrgb version 1998.09.30.

Copyright and contact information is available in the jstools documentation.

Invocation and Usage

jcolrgb [-prompt prompt] [-title title]

Invoking jcolrgb causes a panel to appear that lets the user select a colour by RGB value using three sliders. A patch of the current colour is displayed. When the user clicks OK, the current colour is written to standard output. A label displaying prompt will be at the top of the panel, and it's window­manager title will be title.

Both prompt and title are localisable.

For more details, see the documentation for j:prompt_colour_rgb in the jprompts.tcl library.
