Interface AccessibleHandleProvider
public interface AccessibleHandleProvider
This class provides keyboard accessibility support for the
Handles
of the primary-selected EditPart
. Handles are grabbable
regions on the screen. Typically the user will grab a handle by pressing and
holding the mouse button. This function must also be available via the
keyboard for accessibility reasons. Even mouse Users will appreciate the
fine-grained control offered by the keyboard for operations like "nudging".
The SelectionTool is the primary client for Handles. When it is active, the PERIOD keystroke will cycle through the list of Accessible locations (Points) supplied by the current EditPart. The "current EditPart" is defined as the EditPart with primary selection.
