The "item.ss" test (use load/cd) creates a frame to select
among several types of control-testing frames:
* Big - Tests basic controls; try everything
* Medium - Tests sliders & gauges; keep a new Big or
Medium frame open while getting a new Medium
frame to use the "Enable Previous Frame" test
* Menu - contains its own test instructions
* Button, Checkbox, etc. - Test everything, watching for
messages in the console
For Big & Medium, verify that hide & disbale work (via the checkboxes
on the right). Hiding or disabling a panel should hde or disable all
its contained controls. Disbaling a frame (a "Previous" frame) should
also disbale all of the contained controls. When "Null label" is
used, there should *not* be extra space left where a label might have
gone.
---------------------------------------------------------------------------
The "draw.ss" test (use load/cd) tests drawing commands. There
is a checkbox for testing drawing into an intermediate offscreen
bitmap as well. The drawing area should have the following
features:
At the top, "Pen 0 x 0" in a consistent font (i.e., re-painting
should not change the font)
"Pen 1 x 1" in a possibly different font
"Pen 2 x 2" in a bold font (bold version of 1x1 font)
the drawings under 0x0 and 1x1 should look the same:
TopLeft: h-line should be left-aligned with box below it,
but extend 1 extra pixel. v-line similarly should be
top-aligned and 1 pixel longer. The lines should not
touch the box - there should be 2 pixels of space.
Top: Lines for the rotated L's should join in a sharp corner
Second from Top: like top-left, but lines should touch the box
Four shape lines: First and second should be exactly the same
shape, with the first hollow and the second filled.
Third shape and 2x2 shapes are ill-defined.
Octagons: two hollow octagons exactly the same shape.
Line: actually two lines, but they should form a single
unbroken line
Images: MrEd logo (b & w)
BB logo (color)
Down-left arrow (b & w)
Down-left arrow - B & W, *not* red
Down-left arrow - red with white background
BB logo, possibly reddened
Down-left arrow - red with *white* background
---------------------------------------------------------------------------
The "imred.ss" test is used to check for memory leaks in a loop
invoking the mred system. Call the `go' procedure with a list
of symbol flags:
'force not included:
Use the current eventspaces; expects mred:run-exit-callbacks
to terminate everything properly
'force included:
Use a new eventspace; don't run mred:run-exit-callbacks and
call wx:kill-eventspace instead.
'console included:
Open a MrEd console
'thread included:
Spawn a sleeping-and-looping thread during each invocation.
Also tests semaphore-callback (because it has to)
'eventspace included:
Create a new sub-eventspace during each invocation with
a wx:frame% shown
---------------------------------------------------------------------------
The "mem.ss" test should be loaded at startup:
mred -nu -f tests/mem.ss
It will create a lot of frames and instance of other objects,
reporting memory information along the way. At the end,
before the last memory dump, objects that are still allocated
are displayed like this:
(frame (1 . 5))
This means that the frame allocated by thread #1 at cycle 5
(counting down from some number) hasn't been garbage-collected.
If there's a few of these lines (less than 10), that's ok.
A large number of lines indicates a GC problem.
---------------------------------------------------------------------------
The "setup.ss" test is a randomized test of the MrEd classes that tests
MrEd's stability. Load/cd setup.ss, and then run
(init)
This attempts to create instances of classes using random
intialization arguments. (init) can be run any number of times. Then
run
(call-all-random)
This calls every method of every class (skipping some "dangerous" ones
that modify the file system) with a random instance and with random
arguments.

Version 51: ??, 1997
X Windows: window manager close-frame request is ignored
when a modal dialog is in control
Added security so that wx:snip% methods cannot be overridden
to crash MrEd
Fixed wx:canvas% scrolling on all platforms; the style flags
wx:const-hscroll and wx:const-vscroll must be used at
canvas-creation to set up for scrolling. Removed the
enable-scrolling method from wx:canvas%. Renamed the method
get-scroll-page-units to get-scroll-units. Added methods
get-scroll-pos, get-scroll-range, and get-scroll-page.
The wx:canvas% wx:const-backingstore and wx:const-retained
style flags have been removed.
Removed wx:key-event%'s position method and added get-x,
get-y, set-x, and set-y
Changed default pen in DC to width 0 instead of 1
Added get-max-view method to wx:media-admin%
Revised wx:media-buffer%'s cursor system for better
cooperation with embedded buffers; instead of handling
the cursor in on-default-event, added a method adjust-cursor
to buffers and snips, and replaced admin's set-cursor with
update-cursor
Added refresh-delayed? predicate to wx:media-buffer%, useful
for deciding whether a buffer (or one of its enclosing
buffers) is in an edit-sequence
Added a --pre flag for evaluating an expression in a
MzScheme-only namespace at startup. This flag is intended
for use with image dumps (see the MzScheme manual)
Removed wx:copy-file; MzScheme now has copy-file
Fixed wx:media-stream-in%'s get-string (it was adding an
extra nul character)
Removed error dialogs when wx:media-buffer%'s load-file or
save-file fails
Windows: fixed canvas mouse events; button-down event grabs
the mouse until the next button-up event
Windows: fixed initial setting of DC text mode: transparent
instead of opaque
X Windows: fixed wx:frame's iconize and iconized? methods,
ignoring the X idea of not de-iconifying windows that were
iconified by the user
Removed wx:exit
Version 50: August 26, 1997

destination area; old [documented] functionality
is available via max-x and max-y

Fixed and normalized PostScript drawing
Removed wx:dc% methods: device-to-logical-x, etc.
Windows wx:display-size changed to return the size of the
screen not including the task bar
Windows: finally fixed scale for [non-PostScript] printing
Added wx:[un]register-collecting-blit
X Windows: Fixed use of colormap by loaded bitmap images
Added an optional argument to wx:media-buffer's print method
to supporting fitting to the destination page
X Windows: Saving as xbm works for bitmaps of any depth
MzScheme pathname expansion performed by all wx: toolbox
procedures that take a pathname
X Windows Xt: removed excessive borders on wx:canvas% objects
X Windows Xt: removed 2 pixel offset for a single auto-sized
child in a wx:frame% or wx:dialog-box%
Windows: Fixed scrollbars on editor buffers; they're always
shown now, but the editor never gets confused about the size
Fixed on-size, pre-on-char, and pre-on-event for wx:item%
subclasses
Fixed confusing argument type and number error messages
for overloaded methods of primitive classes
Version 49: May 31, 1997
Object system changes: see mzscheme/HISTORY for details
Fixed Mac event-handling and many other Mac things
Fixed garbage collection of hidden frames under Windows (!)
Panels, canvases, and controls that are both hidden and
inaccessible are now garbage-collected
Disabled controls are reliably grayed-out, including items
within a disabled panel
Instances of wx:pen%, wx:brush%, or wx:pen% that are
selected into a drawing context cannot be mutated
Immutability of objects obtained via wx:the-XXX-list is
enforced
Controls for Windows, Xt are created with the "System" family
rather than the "Default" family (using resources)
Single wx:bitmap% object can be used by multiple controls
and/or pens and/or brushes
Fixed Motif image-label radio button
wx:find-directory replaced with wx:find-path
All wx:dc% instances have a default font for drawing
wx:const-copy blit never uses the pen/background color;
new blit mode wx:const-colour uses current pen

keyboards where NumLock is Mod3)
Fixed wx:timer% bug that caused autosaving to not work
Fixed eventspace bugs
Fixed .bmp reading when smaller-than-max colormap is provided
Fixed interlaced .gif reading for Windows and MacOS
Xt: fixed default height of wx:text% items
Xt: In a wx:mouse-event% instance, type wx:const-type-XXX-down
implies get-XXX-down => #t (formerly #f)
Removed wx:group-box% class; use a panel with a border, instead
Removed wx:tool-bar% class
wx:choice% get-columns and set-columns no longer supported
Added wx:gauge% methods: get-value and get-range
wx:media-pasteboard% bug fixes and improvements: raise, lower,
set-before, and set-after methods now work
wx:list-box% set-client-data and get-client-data work with
any Scheme data type
Windows and X Windows: Break key changed back to shift-ctl-c
instead of ctl-c (to avoid conflicts with Emacs-std keyboard
mappings)
Version 48: Skipped to avoid confusion with Scheme48
Version 47: January 11, 1997
WARNING: multiple inhertance is going away in 48
Added overwrite-styles? arg to wx:media-buffer%'s read-from-file,
and added get-/set-load-overwrites-styles methods
Modified wx:media-buffer%'s set-caret-owner to provide more
levels of focus control

likely to be in 46.
Xt and Mac: "&" stripped from control labels (matches Windows/Motif), sortof
Version 44: September 9, 1996

Old standard system no longer compatible
Project system improved
Many bugs fixed in the new standard system
Version 0.32: December 4, 1995
New standard system:
* The console I/O is completely different. It works more
like an Emacs shell. Use M-p and M-n to access previously
entered expressions. (read) will now read from the console.
* All mred:std-<x> variables have been eliminated. For each
mred:<x>%, there is now a procedure mred:make-<x>% that takes a
superclass and returns a new class.
* The frame and buffer hierarchies have changed a little.
* From a mred:edit% object, you can get to its canvas or frame.
* The menubar/menu system is completely revised. You don't have to
deal with menu ids much anymore. Menus and menu items can now be
dynamically added and removed.
* Keymap chaining works differently.
* The new Scheme project system is roughly in place. This will let you
develop Scheme programs by organizing Scheme files within a project.
Projects help manage loading program files into the
evaluator and uses Shriram's Zodiac/Aries packages to
provide debugging facilities. This will be improved in the near
future.
The old standard system is available in the "oldsys" directory.

Many bugs fixed in the new standard system
Version 0.32: December 4, 1995
New standard system:
* The console I/O is completely different. It works more
like an Emacs shell. Use M-p and M-n to access previously
entered expressions. (read) will now read from the console.
* All mred:std-<x> variables have been eliminated. For each
mred:<x>%, there is now a procedure mred:make-<x>% that takes a
superclass and returns a new class.
* The frame and buffer hierarchies have changed a little.
* From a mred:edit% object, you can get to its canvas or frame.
* The menubar/menu system is completely revised. You don't have to
deal with menu ids much anymore. Menus and menu items can now be
dynamically added and removed.
* Keymap chaining works differently.
* The new Scheme project system is roughly in place. This will let you
develop Scheme programs by organizing Scheme files within a project.
Projects help manage loading program files into the
evaluator and uses Shriram's Zodiac/Aries packages to
provide debugging facilities. This will be improved in the near
future.
The old standard system is available in the "oldsys" directory.
