java - Keep DROP_DOWN ToolItem highlighted while menu is shown -

-

i have toolitem swt.drop_down, , selectionlistener popup menu few menuitem.

the toolitem highlighted when mouseover, , on click submenu appears. however, toolitem no longer highlighted. there way keep highlighted until select 1 of menu items (or click somewhere else close)?

enter image description here

swt uses native widgets of platform runs on. hence, highlighting behavior entirely platforms implementation.

i fear there no way highlight tool button while drop-down menu shown.
