Examples of org.eclipse.ui.internal.layout.TrimCommonUIHandle

org.eclipse.ui.internal.layout.TrimCommonUIHandle
This control provides common UI functionality for trim elements. Its lifecycle is managed by the TrimLayout which automatically adds a UI handle to all added trim elements. It uses an instance of a CoolBar to provide the platform-specific drag affordance.
It provides the following features:
Drag affordance and handling:
1. Drag affordance is provided in the paintControl method
2. Drag handling is provided to allow rearrangement within a trim side or to other sides, depending on the values returned by IWindowTrim.getValidSides
Context Menu:
1. A "Dock on" menu item is provided to allow changing the side, depending on the values returned by IWindowTrim.getValidSides
2. A "Close" menu item is provided to allow the User to close (hide) the trim element, based on the value returned by IWindowTrim.isCloseable
