Interface IsCollapsible

All Known Implementing Classes:
ButtonCellBase, TextButtonCell

public interface IsCollapsible
Indicates that a UI component can be collapsed next to another UI component, thus sharing a common border. This allows UI components to appear flush against each other without extra thick borders.

Before collapse:

   ---------    ----------    ---------
  | ButtonA |  |  ButtonB |  | ButtonC |
   ---------    ----------    ---------
 

After collapse:

   -----------------------------
  | ButtonA | ButtonB | ButtonC |
   -----------------------------
 

In the above example, ButtonA has right-side collapsed, ButtonB has both left and right-side collapsed, and ButtonC has left-side collapsed.
