Hidden Gems: “A Custom View with Mouse Events, Part 2”

Posted on in Categories Hidden Gems, Tutorial

The purpose of the Hidden Gems Screencast is to give developers who use Cincom Smalltalk some valuable insight into the useful abilities of the products that may not be obvious. 

Last month, we built a “DateAxisApp” to show how to build custom views that respond to mouse events like the mouse scroll wheel.
This month’s Hidden Gems will enhance that application to show how to take that beginning idea and build it into something more pragmatic that we will continue to take forward.

If you have comments or ideas for future Hidden Gems, please send feedback and suggestions to
