Tree Object in Run-time

A tree is a hierarchical display of data, similar to the system tree. However, unlike the system tree, trees in analysis displays do not provide navigation to other displays or web pages; instead, a tree displays data in a hierarchical manner, as the following figure shows.


Refer to the following sections for more information about the tree object:

Navigating the tree object

You can navigate a tree from the run-time environment using a mouse or keyboard. The following figure shows how to navigate a tree with a mouse.


You can select multiple items in the tree by clicking the mouse while holding down the Shift key (Shift-clicking) or the Ctrl key (Control-clicking). Shift-clicking selects multiple consecutive items. Control-clicking selects multiple non-consecutive items.

To navigate a tree using the keyboard, refer to the following table for the keystrokes supported.

Drag and Drop support

Data items can be dragged from a tree object and dropped onto a grid within a Proficy Portal display. See Dragging and Dropping data in Run-time for more information.

Tree Grids

A grid within a Tree object is much more limited than a Grid object. During run-time, the user can use the Tree Grid as follows:

The tree grid's configuration is not modifiable in run-time.
