The XCON toolkit has been created and used for a number of applications for Fermilab and IHEP accelerator control. It provides an easy way to create a sophisticated graphical user interface for control applications, in particular ones requiring complex synoptic diagrams. The toolkit is based on Motif and contains a diverse set of control widgets in addition to a powerful graphical editor and the capability to include GIF images as a screen background. Equipment access is implemented as a library layer which allows this package to be adapted other control systems. The XCON toolkit description and a few examples of its use are presented in this report.
