Color Drag and Drop Demo

This page explains the Color Drag & Drop demonstration. This small demonstration of Motif and X Window application programming illustrates several skills. The mains ones that you are intended to notice are Drag and Drop, Mouse Handling and Color Manipulation.
The illustrations below show two separate applications that interact by allowing the user to Drag and Drop of Color information between the windows. The window titled 'draw' is a slightly modified version of an application from the book "The X Window System, Programming and Aplications with Xt/OSF Motif Edition" by Douglas Young.
The small colored window titled "xcolorswish" is a small demonstration program created by the Interfacers to demonstrate the coding required for Drag and Drop, Mouse Handling and Color Manipulation.
