A Pane (Tab) Group is an interface element that is exposed at the top-level of the interface and allows for stacking panes within the same area. A pane group provides an easy-to-use selection mechanism for pulling items lower in the stack to the front.

A pane group exists only as a container for one or more Pane (Tab), and includes a set of common controls for working with them. A pane group can be docked (“anchored”) within a Dock Area or be made to float (“undocked”) in a dock-able frame.

Below is a list of interface elements that a Pane Group can exist within:

• Dock Area - an interface element that serves as a container consisting of columns and/or rows that allow multiple pane groups to be docked next to one another

Below is a list of interface elements that exist within a pane group:

• pane_group_tab_bar - an interface element that serves as a container for the tabs that are attached to panes, the Active Pane Options Button, and the Pane Group Scroll Buttons
• pane_options_button - a button that when pressed causes the Pane (Tab) Option Menu for the top-most active pane in the pane group to be displayed
• Pane (Tab) - a container for various interface elements that are closely associated with a particular label and are grouped together to provide information and/or interaction, given a particular context
