Tech Tip: Remember to Update Old Widgets

PRODUCT: 4D | VERSION: 18 | PLATFORM: Mac & Win

Published On: November 17, 2020

When upgrading databases to newer versions in 4D, keep in mind of older 4D widgets that may be used in the database. Widgets from older versions of 4D may use commands that are now obsolete or unsrupported. If errors occur from 4D widgets after performing a database upgrade, drag a new version of the widget from the object library in the current 4D version to replace the older widget. The new widgets are updated to be compatible with current versions.

Note: Reminder that the object library will contain widgets from the older version if an older version of 4D Widgets.4dbase is placed in the Components folder next to the database structrure.

Hi Chris, If you would like to share your date widgets, please do on 4D forums (https://discuss.4d.com). Many 4D developers, including 4D Engineers, are monitoring the forums.

Would 4D be curious to see the date entry widget / date picker and other widgets I've developed (in a component) that are compatible with Form objects? (i.e. datasource: Object, and it operates on an attribute of that object). It enables the instant ability to respond based on what is input in the widget. Lots of good things.
