The Reload widget

Available since version: 2014
Author: Christian Mayer


With the reload widget, the visu is added a switch, which allows to reload the full visu in the browser.


For a general understanding of how the configuration files are structured and what elements and attributes are it is recommended to read this section first: visu-config-details.

The behaviour and appearance of the Reload widget can be influenced by using certain attributes and elements. The following tables show the allowed attributes and elements and their possible values. The screenshots show, how both can be edited in the editor.

Attributes underlined by ..... are mandatory, all the others are optional and be omitted.

It is possible to manually edit the visu_config.xml and add an entry for the Reload widget.
