Visualization extensions use the same set of technologies as standard Qlik Sense visualizations, and if developed properly, the handling of them is identical to standard visualizations.
Themes are used to style your Qlik Sense apps and you can create your own custom themes based on your company standards.
Custom objects are visualization objects you build to extend the visualization capabilities of Qlik Sense using standard web technologies. A custom visualization object can be seen as a plugin mechanism that allows developers to combine the power of the Qlik Sense APIs with the capabilities of the web.
There are two types of custom objects:
- Widgets: simple app objects created using only HTML and CSS.
In the hub you find the widgets and visualization extensions available to you in the assets panel under Custom objects.
