The Tcl 7.6 and Tk 4.2 releases
|
| 493 |
|
|
|
| 494 |
|
|
This page contains information about Tcl 7.6 and Tk4.2,
|
| 495 |
|
|
which are the most recent
|
| 496 |
|
|
releases of the Tcl scripting language and the Tk toolk
|
| 497 |
|
|
it. The first beta versions of these
|
| 498 |
|
|
releases were released on August 30, 1996. These releas
|
| 499 |
|
|
es contain only minor changes,
|
| 500 |
|
|
so we hope to have only a single beta release and to
|
| 501 |
|
|
go final in early October, 1996.
|
| 502 |
|
|
|
| 503 |
|
|
|
| 504 |
|
|
What's new
|
| 505 |
|
|
|
| 506 |
|
|
The most important changes in the releases are summariz
|
| 507 |
|
|
ed below. See the README
|
| 508 |
|
|
and changes files in the distributions for more complet
|
| 509 |
|
|
e information on what has
|
| 510 |
|
|
changed, including both feature changes and bug fixes.
|
| 511 |
|
|
|
| 512 |
|
|
There are new options to the file command for
|
| 513 |
|
|
copying files (file copy),
|
| 514 |
|
|
deleting files and directories (file delete),
|
| 515 |
|
|
creating directories (file
|
| 516 |
|
|
mkdir), and renaming files (file rename).
|
| 517 |
|
|
The implementation of exec has been improved great
|
| 518 |
|
|
ly for Windows 95 and
|
| 519 |
|
|
Windows NT.
|
| 520 |
|
|
There is a new memory allocator for the Macintosh
|
| 521 |
|
|
version, which should be
|
| 522 |
|
|
more efficient than the old one.
|
| 523 |
|
|
Tk's grid geometry manager has been completely
|
| 524 |
|
|
rewritten. The layout
|
| 525 |
|
|
algorithm produces much better layouts than before
|
| 526 |
|
|
, especially where rows or
|
| 527 |
|
|
columns were stretchable.
|
| 528 |
|
|
There are new commands for creating common dialog
|
| 529 |
|
|
boxes:
|
| 530 |
|
|
tk_chooseColor, tk_getOpenFile, tk_getSaveFile and
|
| 531 |
|
|
tk_messageBox. These use native dialog boxes if
|
| 532 |
|
|
they are available.
|
| 533 |
|
|
There is a new virtual event mechanism for handlin
|
| 534 |
|
|
g events in a more portable
|
| 535 |
|
|
way. See the new command event. It also allows
|
| 536 |
|
|
events (both physical and
|
| 537 |
|
|
virtual) to be generated dynamically.
|
| 538 |
|
|
|
| 539 |
|
|
Tcl 7.6 and Tk 4.2 are backwards-compatible with Tcl
|
| 540 |
|
|
7.5 and Tk 4.1 except for
|
| 541 |
|
|
changes in the C APIs for custom channel drivers. Scrip
|
| 542 |
|
|
ts written for earlier releases
|
| 543 |
|
|
should work on these new releases as well.
|
| 544 |

Obtaining The Releases
|
| 546 |
|
|
|
| 547 |
|
|
Binary Releases
|
| 548 |
|
|
|
| 549 |
|
|
Pre-compiled releases are available for the following
|
| 550 |
|
|
platforms:
|
| 551 |
|
|
|
| 552 |
|
|
Windows 3.1, Windows 95, and Windows NT: Fetch
|
| 553 |
|
|
ftp://ftp.sunlabs.com/pub/tcl/win42b1.exe, then
|
| 554 |
|
|
execute it. The file is a
|
| 555 |
|
|
self-extracting executable. It will install the
|
| 556 |
|
|
Tcl and Tk libraries, the wish and
|
| 557 |
|
|
tclsh programs, and documentation.
|
| 558 |
|
|
Macintosh (both 68K and PowerPC): Fetch
|
| 559 |
|
|
ftp://ftp.sunlabs.com/pub/tcl/mactk4.2b1.sea.hqx.
|
| 560 |
|
|
The file is in binhex format,
|
| 561 |
|
|
which is understood by Fetch, StuffIt, and many
|
| 562 |
|
|
other Mac utilities. The
|
| 563 |
|
|
unpacked file is a self-installing executable:
|
| 564 |
|
|
double-click on it and it will create a
|
| 565 |
|
|
folder containing all that you need to run Tcl
|
| 566 |
|
|
and Tk.
|
| 567 |
|
|
UNIX (Solaris 2.* and SunOS, other systems
|
| 568 |
