472 :     and a function to alter the background of a widget.
473 :    
474 :     - Toggle and button protocol has changed. Command and toggle buttons
475 :     register a change on button up, not on button down. If button up
476 :     occurs off the widget, no change is registered. Event streams for
477 :     general buttons now terminate with either button up or exit, the latter
478 :     indicating the mouse has left the widget. Buttons and toggles also now
479 :     provide active/inactive state.

482 :     eXene-0.3 (released 12/03/91)
483 :     -----------------------------
484 :    
485 :     GLOBAL CHANGES:
486 :     - eXene is now based on CML-0.9.4; this very required minor changes to
487 :     eXene (now using 0.9.6).
488 :    
489 :     - ported to SML/NJ 0.71. Most changes were a result of the Array structure
490 :     not being open by default, and by Array.sub no longer being an infix operator.
491 :     Changed the representation of pen_t values to use immutable vectors.
492 :    
493 :     LIBRARY CHANGES
494 :     - fixed typechecking problem in protocol/xdisplay.sml that was exposed
495 :     by SML/NJ 0.70.
496 :    
497 :     - replaced draw_dst_t datatype with abstract drawable_t type. This is
498 :     part of the support for rubber-banding.
499 :    
500 :     - fixed xio.sml bug caused by a faulty understanding of the sequencing
501 :     semantics of the protocol.
502 :    
503 :     - fixed bugs in gc-server.sml and draw-master.sml reported by Huimin Lin
504 :     (huimin@@cogs.susx.ac.uk).
505 :    
506 :     - fixed bug in HashUtil.mapList
507 :    
508 :     - changed remove function for hash tables to return the removed item. This
509 :     affected the hash tables defined in util/{hash-util.sml,hash-xid.sml},
510 :     window/hash-window.sml and user/eXene-base.sml.
511 :    
512 :     - added window-tree locking mechanism to the window registry.
513 :    
514 :     - modified asynchronous blt operations to use a promise-style implementation.
515 :    
516 :     - added updatePen operation for functional updates of pens.
517 :    
518 :     - added createOverlay to support rubber-banding.
519 :    
520 :     - new Spline module providing functions to compute Bezier cubic sections,
521 :     and open and closed B-splines.
522 :    
523 :     - added copyBlt and copyBltEvt.
524 :    
525 :     - fixed bug in decoding font info in xreply.sml (wrong offset)
526 :    
527 :     WIDGET CHANGES
528 :     - fixed possible deadlock arising from parent not always servicing a child's
529 :     CO event. This affected box.sml and field-edit.sml.
530 :    
531 :     - added new text list widget. The widget provides a vertical or horizontal
532 :     display of text items, and events associated with the user choosing items.
533 :    
534 :     - the ButtonView structure now provides a new view mkTextBtn, which
535 :     generalizes mkLabelBtn (rectangular buttons with string labels) by
536 :     allowing the programmer to specify the border width and text alignment
537 :     within the button.
538 :    
539 :     - fixed bug in Frame widget that was causing deadlock.
540 :    
541 :     - the SimpleMenu module has seen various bug fixes and style
542 :     changes, as well as the addition of a low-level menu routine
543 :     for providing pop-up menus within widgets.
544 :    
545 :     - there is now a working vtty widget (thanks to Thomas Yan for finishing
546 :     our code)
547 :    
548 :     - the Canvas widget now provides a drawable, so that the library drawing
549 :     routines can be used.

562 :     Also, the PV_Exposures field for pens has been eliminated.
563 :    
564 :     - destroyWindow is now handled by the draw-master, which avoids a race
565 :     with any pending drawing requests on the window. This was a problem
566 :     with popup windows.
567 :    
568 :     - added Geometry.inside; test if a rectangle is inside another
569 :
