See this tutorial for details on how to develop a tabular view for your ONOS Application.

View Header

At the top of every tabular view is a header providing the table title on the left, and a set of control buttons on the right.

Control Buttons

The control buttons provide additional functionality for the table view. Most tables include a Refresh-enabled toggle button. Other buttons may also be provided, depending on the view.

Refresh ButtonRefresh: Tables with this button auto-refresh every two seconds. Click this button to toggle auto-refresh off and on again.

Table Body

The body of the table is scrollable. Your browser's Find/Search capabilities can be used to quickly find something in the table; use Cmd-F (Mac) or Ctrl-F (Windows).

"Loading..." Animation

If the server takes more than a few hundred milliseconds to respond, a "loading..." animation will appear, indicating that the client is waiting for a response from the server:

Table Columns

The data in the table is sortable; click on a column header to sort rows by values in that column. A small triangle indicating the sort direction will be displayed after the column name:

Table Rows

Each row in the table represents a single item. When an item is added or updated, the row will briefly flash yellow, as shown below:

Selectable Rows

Tables may implement selectable rows: clicking on a row highlights it and displays a details panel with more information about the selected item. Clicking on a different row selects a new item and updates the details panel appropriately. Clicking on the selected row again (or pressing the Esc key) deselects the item:

Empty Tables

If there are no items to display, an "empty" table will be shown:
