******************
|
|
* MrEd 100 *
|
|
******************
|
|
|
|
The entity known as "MrEd" in previous versions has been split
|
|
up. MrEd 53 comprised two parts:
|
|
|
|
* a low-level toolbox (containing names prefixed with wx:) that was
|
|
too primitive for real programming (no geometry management); and
|
|
|
|
* an application framework (containing names prefixed with mred:)
|
|
that provided useful window classes (with geometry management) but
|
|
much, much more, making it too heavyweight for simple GUI programs.
|
|
|
|
In MrEd 100, we split up the core toolbox and the application
|
|
framework. The new toolbox includes the most useful stuff from the
|
|
old mred: domain, such as the windowing classes with geometry
|
|
management. These mred: classes replace clumsy wx: classes. Useless
|
|
and redundant methods have been eliminated. The overall effect is that
|
|
the MrEd 100 toolbox is both smaller and better than the core toolbox
|
|
in MrEd 53.
|
|
|
|
The old mred: classes that implement the application framework has been
|
|
moved into a separate, optional library. It is no longer necessary to
|
|
understand units, collections, and the framework for bootstrapping large
|
|
programs to get a simple MrEd application going.
|
|
|
|
Unlike MrEd 53, MrEd 100 is just an extension of MzScheme with a
|
|
graphical toolbox. No extra files are needed to start the MrEd
|
|
executable. Command-line handling for MrEd 100 is the same as for
|
|
MzScheme --- the only difference is that MrEd executes
|
|
'(graphical-read-eval-print-loop)' on startup instead of
|
|
'(read-eval-print-loop)'.
|
|
|
|
MrEd's `graphical-read-eval-print-loop' implements a *very* primitive
|
|
GUI REPL, not the relatively useful REPL that came with the old MrEd
|
|
toolbox/framework combo. DrScheme now provides the only development
|
|
environment for MrEd. But unlike previous releases, DrScheme 100
|
|
provides a REPL that matches MrEd's language exactly.
|
|
|
|
Everything works in MrEd 100. Previous versions of MrEd made all of
|
|
the low-level toolbox (wxWindows) available, regardless of how well
|
|
certain parts worked (or how consistently across platforms). Over many
|
|
releases, we fixed a lot of things that didn't work, but it was still
|
|
hard to say which parts of the toolbox were reliable, even in MrEd
|
|
53. For 100, we've turned the tables: everything that is truly useful
|
|
works (to the best of our testing), and the other junk has been thrown
|
|
away.

======================================================================
|
|
0. Highlights of the New MrEd Toolbox
|
|
======================================================================
|
|
|
|
We didn't try to develop an improved windowing model, but instead
|
|
tried to clean up the existing model. The following are a few
|
|
highlights of the revision:
|
|
|
|
* The wx/mred split has been eliminated. The wx methods for
|
|
manually managing the geometry of windows have been eliminated; the
|
|
only way to set control positions explicitly is to derive a new
|
|
panel class.
|
|
|
|
The class hierarchy has been rerranged. For example, dialog%
|
|
is no longer a subclass of panel%, which is itself no longer
|
|
a subclass of canvas%.
|
|
|
|
* Interfaces are widely used in the toolbox. The old toolbox had
|
|
"classes" like wx:window% that could not be instantiated. The
|
|
new toolbox has a window<%> interface ("<%>" is the conventional
|
|
suffix for interfaces), and all buit-in classes can be
|
|
instantiated.
|
|
|
|
* Instead of null, #f is used for the `no appropriate value' value,
|
|
such as the parent argument for a frame that doesn't have a
|
|
parent window, or the result for get-label when the menu doesn't
|
|
have a label.
|
|
|
|
* There are hardly any wx:const-... values. Instead, methods that
|
|
used to take a single (numerical) wx:const- flag now take a symbol,
|
|
and methods that used to take bitwise-ior'd wx:const- integers now
|
|
take a list of symbols. For example, wx:const-horizontal was
|
|
replaced by 'horizontal, and wx:const-bitmap-type-gif was replaced
|
|
with 'gif.
|
|
|
|
* The menu system was turned upside-down, giving it a structure more
|
|
like rest of the toolbox. For example, instead of creating a menu
|
|
bar and then calling a frame's set-menu-bar method, the new way to
|
|
create a menu bar is to provide the frame as an initialization
|
|
argument when creating a menu bar. Menus are created by supplying
|
|
the parent menu bar as an initialization argument (or a parent menu
|
|
to create a submenu). Menu items are created by instantiating
|
|
menu-item% or checkable-menu-item% with a menu argument. There are
|
|
no menu ids anywhere; when a menu item is selected, the callback
|
|
associated with the menu item is executed (just like when a button
|
|
is clicked).
|
|
|
|
* Initialization arguments for creating windows have been re-ordered.
|
|
In general, the order is something like the following:
|
|
|
|
label [sub-labels] callback parent [init-value] style
|
|
^- e.g., items in a radio box
|
|
|
|
where style is now a list of symbols.
|
|
|
|
* The "media" names have changed. Roughly, we replaced "media" with
|
|
"editor", or drop it when "editor" isn't useful. Here's the name
|
|
mapping for some commonly used classes:
|
|
|
|
media-canvas% => editor-canvas%
|
|
media-buffer% => editor<%>
|
|
media-edit% => text%
|
|
media-pasteboard% => pasteboard%
|
|
snip% => snip%
|
|
media-snip% => editor-snip%
|
|
text-snip% => string-snip% (to avoid confusion)
|
|
|
|
Methods of text% (formerly media-edit%) check that position, line,
|
|
and paragraph arguments are non-negative. In methods where -1
|
|
(really any negative value) had a special meaning, a symbol is now
|
|
used. For example, the old call
|
|
(send (make-object media-edit%) insert "Hello" 0 -1)
|
|
translates to a use of 'same instead of -1:
|
|
(send (make-object text%) insert "Hello" 0 'same)
|
|
|
|
Many of the old on-XXX methods for editors used to return a Boolean
|
|
value to indicate whether the action should proceed (e.g.,
|
|
on-insert in media-edit%). This did not work well with composing
|
|
class extensions. In MrEd 100, there is a parallel set of can-XXX?
|
|
methods (e.g., can-insert? in text%) that first determine whether
|
|
the opration should proceed; if so, on-XXX is called (its result is
|
|
ignored), the operation is performed, and after-XXX is called.
|
|
|
|
Aside from the renaming and checking, little has changed in the
|
|
editor toolbox, but it is a little better integrated with
|
|
system-wide keyboard focus methods. For example, a frame% has a
|
|
get-focus-window method, which returns the frame's subwindow with
|
|
the current focus, but it also has a get-focus-object method, which
|
|
will return an editor<%> object if an editor-canvas has the
|
|
keyboard focus.
|
|
|
|
* The text-field% control (formerly wx:text% and wx:multi-text%) now
|
|
works well on all platforms because it is implemented using the
|
|
editor classes. (The equivalent of a wxmulti-text% is specified via
|
|
a style flag when creating a text-field%.)
|
|
|
|
* The command-event% class was changed to control-event%. It has very
|
|
few methods, since the old information can be extracted from the
|
|
control.
|
|
|
|
* Some methods have been renamed to be either more (accurately)
|
|
descriptive or more consistent with other method names.
|
|
|
|
* The device context system has been changed to provide a larger set
|
|
of methods that paint consistently on all platforms. Some drawing
|
|
modes eliminated, ... [still hashing out this part]
|
|
|
|
The blit method works directly on bitmaps.
|
|
|
|
The canvas% class no longer supplies drawing methods. Instead,
|
|
get-dc to get a drawing context (which always has a more complete
|
|
set of methods, anyway).
|
|
|
|
* American spelling is used everywhere: colour -> color, centre
|
|
-> center.
|
|
|
|
The next section shows the new interface/class hierarchy for windows a
|
|
few other parts of the toolbox, and the section after that lists all
|
|
the methods of the new interfaces and classes. Section 3 lists the new
|
|
complete set of MrEd procedures, showing the arguments for selected
|
|
new procedures. Section 4 provides a mapping from the old wx:const-XXX
|
|
constants to the new symbols. Finally, Section 5 lists some of the
|
|
small and relatively subtle changes in 100 (like the HISTORY notes
|
|
that accompany an average MrEd release).

5. Subtle changes
|
|
======================================================================
|
|
|
|
Added queue-callback: (queue-callback proc [hi-priority?])
|
|
|
|
key-event%'s key-code method was removed
|
|
|
|
key-event%'s get-key-code returns a character or a symbol
|
|
instead of a number
|
|
|
|
window<%>'s set-cursor no longer returns the cursor; added get-cursor,
|
|
instead
|
|
|
|
editor-snip%'s resize method no longer calls the embedded buffer's
|
|
set-max-size and set-min-size; now it calls on-display-size
|
|
|
|
{get-set}-{...} PS configuration bundled into an object, an instance of
|
|
ps-setup%; added current-ps-setup parameter.
|
|
|
|
media-buffer%'s do-edit changed to editor<%>'s do-edit-operation,
|
|

TODO: Miscellaneous Cleanup
|
|
-----------------------------
|
|
|
|
DC cleanup. Change dc set-background to take a color instead of a
|
|
brush. Choose a small set of logical drawing modes to implement
|
|
consistently, and perhaps make the drawing mode a property of a
|
|
pen/brush instead of the DC.
|
|
|
|
Implement keyboard-based movement in frames/dialogs
|
|
(implemented in Scheme using on-pre-char).
|
|
|
|
Move editor margin settings into ps-setup%?
