13.5.7 Redisplay of image buttons, and change to accessors

The accessors capi:button-image , capi:button-disabled-image , capi:button-armed-image , capi:button-selected-image and capi:button-selected-armed-image have been changed. When called after the button has been displayed, these accessors now return the value that was set initially. This change also means that buttons with images can reliably be destroyed and then displayed again.

In LispWorks 5.1 and earlier versions these accessors return the loaded image (that is the result of calling gp:load-image ) and buttons with images cannot reliably be displayed again after being destroyed.
