------------------------
GLOBAL CHANGES
- modified sources to use the Char and String interfaces from the
new standard basis.

SendEvent requests (currently only encodeSendSelectionNotify).
[11/20/92]
- modified lib/protocol/xdisplay.sml to retry connection upto 5 times.

This is necessary to avoid premature deallocation of those color
cells, once color finalization is implemented.
- changed "Drawing.autoflush" to "Drawing.feedback"
- Implemented a new, more abstract, color model. Each screen has a color
server that maps abstract color specifications (color_spec_t) to
an abstract representation of colors (color_t). The pixel type is no
longer visible to the user level.
- Added number of buffered messages count to mapped state of draw-master.

- Fixed race condition by adding buffering to the top-level
window server.

lists instead of a list.

datatypes lie in allowed ranges for the X protocol. Added related
exceptions BadRGB, BadDrawParameter, BadPenParameter, BadWindowGeometry
and BadPixmapParameter.
- NoColorCell exception added to EXeneBase (and Color), for attempts to
allocate a new color cell when the color map is full.
- Immutable tiles are now used where pixmaps used to be allowed.
GRAPHICS UTILITIES

(lib/graph_util).
[10/03/92]
- Added routines for drawing/filling rounded rectangles.
[09/03/92]

[02/12/93]
- The AlreadyRealized exception from Widget is now exposed (widget.sml).
[02/12/93]

widget.sml, frame.sml, viewport-sig.sml, viewport.sml
[02/12/93]
- Exceptions BadWidth and MultipleChoices exposed in text-list.sml
[02/11/93]
- Unused exception BadWidth removed from color-rect.sml
[02/11/93]
- setWMHints function added to Shell
- type generators added for types defined by type abbreviation:
wm_args_t, hints_t (shell.sml), bounds_t (widget.sml),
list_item_t (text-list.sml), set_item_t (widget-set.sml),
whereFn_t (simple-menu.sml)

TextList using WidgetSet
(5 November 1992)
- The widget library assumes util-lib library loaded
- Added mkTransientShell and removed setWMHints from Shell
- Added wstate_t type to Widget; replaces button_state_t
- Added sameRoot function to Widget
- Made widgets abstract, with equality function.
- Removed window attributes for widgets. The wrapCreate function
was changed accordingly. Also, removed setBackground function
from Widget; use new background widget instead
- Added several utility functions to Widget: okaySize, compatibleDim,
compatibleSize
- Added ignoreMouse, ignoreKey functions for widgets
- Toggles now take an initial state; in addition, a toggle now
fires its action routine if its state is changed under program control
- Sliders now take an initial state; in addition, there are now functions for
setting the state, plus querying the state and scale
- The function mkSBLayout has been moved to its own structure ScrollLayout
- TextList replaces the ListWidget structure. The user can now
specify an initial state for the items.
- mkColorRect has been added to implement simple colored rectangular regions.
- A background_t widget has been added to implement backgrounds for widgets
- Where possible, composite widgets no longer need a root
argument (structures Frame, ScrollPort, Shape)
- The Box structure now produces a box_layout_t, rather than a widget_t.
(There is the usual widgetOf function.) In addition, one can now
insert, delete, map, and unmap "boxes" in the top level of the box
hierarchy
- A Pile structure has been added. This implements a pile_t type, which
maintains a collection of widgets, only one of which is visible at
a time. Widgets can be inserted and deleted from piles.
(2 November 1992)
- modified str-edit.sml to allow character values in the range
[0xa0-0xff].
- Color type introduced to allow multiple representations; currently
supports RGB and pixel. [NOTE: this has been moved to the library
level]
- New widgets : Divider, MenuButton, ViewPort, ScrollPort
- Label views, text button views and list items
reimplemented to use common text glyph.

and mkFlex added.
- Character insertion and deletion added to TextWidget
- The Widget module now provides filter functions for the input streams,
and a function to alter the background of a widget.
- Toggle and button protocol has changed. Command and toggle buttons
register a change on button up, not on button down. If button up
occurs off the widget, no change is registered. Event streams for
general buttons now terminate with either button up or exit, the latter
indicating the mouse has left the widget. Buttons and toggles also now
provide active/inactive state.
eXene-0.3 (released 12/03/91)
-----------------------------
GLOBAL CHANGES:
- eXene is now based on CML-0.9.4; this very required minor changes to
eXene (now using 0.9.6).
- ported to SML/NJ 0.71. Most changes were a result of the Array structure
not being open by default, and by Array.sub no longer being an infix operator.
Changed the representation of pen_t values to use immutable vectors.
LIBRARY CHANGES
- fixed typechecking problem in protocol/xdisplay.sml that was exposed
by SML/NJ 0.70.
- replaced draw_dst_t datatype with abstract drawable_t type. This is
part of the support for rubber-banding.
- fixed xio.sml bug caused by a faulty understanding of the sequencing
semantics of the protocol.
- fixed bugs in gc-server.sml and draw-master.sml reported by Huimin Lin
(huimin@@cogs.susx.ac.uk).
- fixed bug in HashUtil.mapList
- changed remove function for hash tables to return the removed item. This
affected the hash tables defined in util/{hash-util.sml,hash-xid.sml},
window/hash-window.sml and user/eXene-base.sml.
- added window-tree locking mechanism to the window registry.
- modified asynchronous blt operations to use a promise-style implementation.
- added updatePen operation for functional updates of pens.
- added createOverlay to support rubber-banding.
- new Spline module providing functions to compute Bezier cubic sections,
and open and closed B-splines.
- added copyBlt and copyBltEvt.
- fixed bug in decoding font info in xreply.sml (wrong offset)
WIDGET CHANGES
- fixed possible deadlock arising from parent not always servicing a child's
CO event. This affected box.sml and field-edit.sml.
- added new text list widget. The widget provides a vertical or horizontal
display of text items, and events associated with the user choosing items.
- the ButtonView structure now provides a new view mkTextBtn, which
generalizes mkLabelBtn (rectangular buttons with string labels) by
allowing the programmer to specify the border width and text alignment
within the button.
- fixed bug in Frame widget that was causing deadlock.
- the SimpleMenu module has seen various bug fixes and style
changes, as well as the addition of a low-level menu routine
for providing pop-up menus within widgets.
- there is now a working vtty widget (thanks to Thomas Yan for finishing
our code)
- the Canvas widget now provides a drawable, so that the library drawing
routines can be used.
eXene-0.2 (released 4/27/91)
-----------------------------
LIBRARY CHANGES
- added absolute screen coordinates to mouse event messages
- added tileBlt operation to Drawing
- fixed GraphicsExpose/NoExpose problem. Drawing.bitblt and Drawing.tileBlt
will raise the exception Exposures, if part of the source is unavailable.
Also, the PV_Exposures field for pens has been eliminated.
- destroyWindow is now handled by the draw-master, which avoids a race
with any pending drawing requests on the window. This was a problem
with popup windows.
- added Geometry.inside; test if a rectangle is inside another
- fixed bug in encodePolyRects, etc.
- changed DrawMaster to group adjacent drawing requests that use the same pen.
- fixed the shutdown deadlock that was causing the "eXene-shutdown timeout"
message.
WIDGET CHANGES
- fixed deadlock in widgets/router.sml
- added tileBlt operation to Canvas widget
- the menu widget is fixed
- there is now a text widget
- there is a text-field edit widget
- the bounds_t type has been redefined; see the manual for details.
- the box/glue layouts have been re-implemented. Also, the layout semantics
have changed; see the manual for details.
- the type of Widget.wrapCreate has changed; point_t and size_t arguments were
bundled into a rect_t argument.
- additional button views have been added.
- the shell widget now provides application access to window manager
hints. In addition, the shell automatically registers size hints
with the window manager.
EXAMPLES
- the examples have been updated to use some of the new library features
- a simple example of the menu widget has been added
- a calculator has been implemented using the widget set.
eXene-0.1 (released 3/19/91)
-----------------------------
This was the first release
