NEWS in package ‘tcltk2’

Changes in version 1.2-3

For some reasons, version 1.2-1 on CRAN looks like version 1.2-0 on R-Forge. This version is an update.
tk2ico.XXX() function change (incompatible changes for some of them!) due to drop of winico.dll in favor of the full-Tcl 'ico' package. See ?tk2ico.set.

The new ttk theme introduced in 1.2-0 have introduced a bug preventing the tcltk2 package to load on Windows OS when 'cat' program is not available (this bug was not catch by the test machines which had Rtools, and thus, 'cat', installed). This bug appeared in the internal .isUbuntu() function. Fixed.
A couple of warnings for partial argument matching in tclTaskXXX() functions under R 2.15.0 are corrected.
Documentation and demos for the tablelist Tk widgets are not distributed any more in the tcltk2 package, to keep its size compatible with CRAN requirements (no more than 5mb). Those are available from http://www.nemethi.de/.

Clearlooks ttk theme added and made default theme under Linux. More modern look&feel for ttk widgets under Linux!
Radiance ttk theme created and added. This matches ambiance and radiance themes under Ubuntu 11.x. This is the default theme used in Ubuntu.
The tk widget tablelist is updated to version 5.5.
tk2listbox() is completelly reworked to provide (autohide) scrollbars, integration with the tk2theme() and easier filling of its content.
tk2label is now fully implemented.
Many methods for tk2widget and tk2cfglist objects are now provided.
tk2style(), tk2dataList() and tk2configList() provide info on style, config and data associated with a tk2widget.

When setting options(scipen = -5) or lower, is.tk() returned FALSE, even if Tk package was installed. Corrected.

Little correction in Winico.c that prevented it to compile correctly on all Windows architectures (thanks Prof. B. Ripley for the patch).

Winico.c modified to compile on Windows 64-bit (but still not OK?).
Added ttk themes plastik, keramik and keramik_alt. Ttk theme plastik is now used by default on other platforms than Windows.

New /win/src/Makevars to make it compatible with the double compilation for Windows 32bit and 64bit. Thanks Prof. Brian Ripley.
Correction of the example in ?tk2reg. Thanks Tony Plate.
.onload() now works inside SciViews.

Patch to .onload() and to source code of Winico0.6.c submitted by Prof. Brian Ripley to make tcltk2 working on 64-bit Windows. Thanks.

A bug in tk2mclistbox, clailing for missing -state argument when selecting an item in the box is corrected, thanks to a patch provided by Christiane Raemsch (and slightly modified).

Several Tcl packages are added, or upgraded: autoscroll 1.1 (added) ctext 3.2 (upgraded from 3.1) cursor 0.2 (upgraded from 0.1) datefiled 0.2 (added) Diagrams 0.2 (added) getstring 0.1 (added) history 0.1 (added) ico 0.1 (added, in partial replacement of Winico 0.6 ) ipentry 0.3 (added) khim 1.0 (added) ntext 0.81 (added) snit 1.0 (added, and required by widget) swaplist 0.2 (added) tablelist 4.10 (added) tooltip 1.4 (added and in replacement of the buggy balloon 1.2) widget 3.0 (added)
There are new tclAfterXxx() and tclTaskXxx() functions to schedule tasks to be executed later in R (using the Tcl 'after' function)

tile and Tktable Tcl packages are eliminated. tcltk2 now uses ttk widgets that come with Tk 8.5. You are supposed to install Tktable yourself (optional) if you need it. Note that recent R (version >= 2.9.0) install both Tcl/Tk 8.5 and Tktable 2.9 under Windows and Mac OS X. So, those two Tcl packages should be available without extra work on these OSes.
The little Windows utility execdde.exe is no longer distributed with the tcltk2 package. It is available from http://www.sciviews.org/SciViews-R.
With Tcl/Tk 8.5, system fonts are now correctly initialized. Thus, winSystemFonts() is not needed any more, and it is deleted from the package (it was only used internally at package loading).
The Tcl/Tk package 'Winico' is now provided in source form and its DLL is compiled (Windows only).

Most windows executables were removed. The rest is in /win and a configure.win / cleanup mechanism is used to install them under Windows only.
BinaryFiles is added to declare these binaries.
An error preventing system fonts to load in tk2fonts is corrected (thanks to B. Ripley).
When the package was installed on a path with spaces, the SystemFonts.exe program was not executed properly under Windows. Quoting the command for system() solved the problem (thanks to Pascal Hirsh).
Tile version of paned widget is disabled because it does not work any more with R 2.9.0 - Tcl/Tk 8.5.

Complete rewrite of the package using tile and a larger series of additional tk widgets.
