Overview

Proxy for org.eclipse.swt.widgets.TabItem

Functions differently from other widget proxies.

Glimmer instantiates an SWT Composite alongside the SWT TabItem and returns it for ‘#swt_widget` to allow adding widgets into it.

In order to get the SWT TabItem object, one must call ‘#swt_tab_item`.

Behind the scenes, this creates a tab item widget proxy separately from a composite that is set as the control of the tab item and ‘#swt_widget`.

In order to retrieve the tab item widget proxy, one must call ‘#widget_proxy`
