The Widget column
Ext JS 5 introduced in the last version a lightweight class called widget and a new type of grid column called widget column. Widgets are similar to components. They mainly consist of an Ext.dom.Element
and associated listeners. Also, they are not derived from Ext.Component
. Components have a more complex life cycle.
Note

Ext.ProgressBarWidget

Ext.slider.Widget
orsliderwidget
) - Sparklines (
Ext.sparkline.*
