Ext Widgets
Wt's Ext widgets are a layer around the ExtJS JavaScript
library. The Ext controls can now be used in Wt in the same way
as native Wt widgets, but they have a different look.
Since ExtJS was originally included in Wt, its native widgets
have expanded to include most of the functionality that was
provided by these ExtJS widgets, without any of the drawbacks
from ExtJS. The ExtJS widgets are considered deprecated. If you
are missing functionality (or esthetics) with the native
widgets, please consider filing an
issue.
Download Ext and obtain a proper license from ExtJs. ExtJs is
not included in the Wt download.
