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 Accessibile locations (Points) supplied by the
current EditPart. The "current EditPart" is defined as the EditPart with primary
selection.
