Due to a ransomware attack, the wiki was reverted to a July 2022 version. . We apologize for the lack of a more recent valid backup.
WIP - More details to come soon.
Overview
Applications may provide what we call a "Topology Overlay" – a component that provides new behaviors to the GUI Topology View.
todo: image of topology view
An overlay can:
- augment or override the contents of the Summary Panel
- augment or override the contents of the Details Panel for a selected item
- cause links to be highlighted and/or labeled
- cause devices/hosts to be badged with numeric or iconic information
- provide toolbar buttons to allow the user to invoke new functions
This tutorial walks you through the steps of developing such a component.
Application Set Up
Setting up the application is exactly the same as for the Custom View tutorial, with one minor difference: the choice of archetype in step (2) should be uiover instead of ui:
Currently, the uiover archetype has not been implemented, so the following command will not work until this has been fixed.
(2) Overlay the UI additional components
