<pre>

Subject: [Announce] Tix version 4.1b2 is available

</pre>

   I am pleased to announce the availability of Tix version 4.1b2, the

   first beta release. This version of Tix supports the Unix and

   Microsoft Windows platforms. <p>

   The Tix library has by far the greatest collection of widgets for

   programming with Tcl/Tk. Highlights include: Hierarchical Listbox,

   Directory List/Tree View, SpreadSheet, Tabular Listbox, ComboBox,

   Motif style FileSelectBox, MS Windows style FileSelectBox,

   PanedWindow, NoteBook, Spin Control widget .... and many more. With

   these new widgets, your Tcl/Tk applications will look great and

   interact with your users in intuitive ways. <p>

   For more info about Tix, visit the Tix home page at <a

   href="http://www.xpi.com/tix/"> http://www.xpi.com/tix/ </a>. <p>

   This version of Tix is released under licensing terms similar to

   those of Tcl/Tk. Please read the file license.terms carefully

   before proceeding. <p>

<h3>What's New Since Tix 4.1a3 (the last release)</h3>

<h4>10/13/96</h4>

  <b>New feature:</b> Now XPM image works on Windows. <p>

<h4>10/18/96</h4>

  <b>New feature:</b> New options -editnotifycmd and -editdonecmd for

  the Grid widget to support editing of the entries. <p>

  <b>New feature:</b> New widget <b>TixFloatEntry</b> to support

  editing of DItems. <p>

<h4>10/27/96</h4>

  <b>Feature Change:</b> The following changes are made to the

  configuration and installation of Tix:

  <ul>

    <li> <b>Naming convention of binaries</b>: The binaries for the

         Tk 4.0 target are called tixwish and libtix.a. For Tk 4.1 and

         later, the executable is be called tixwish[Tix version].[Tk version]

         and the library is called libtix[Tix version].[Tk

         version].[lib extension]. For example, tixwish4.1.4.1 and

         libtix4.1.4.2.so. On platforms that do not allow the dot

         character in the names of shared libraries, the dot character

         will be omitted. E.g., libtix4142.so.

    <li> <b>Shared vs static linking</b>: The static binary will be

         created only if the -enable-[tkversion]-shared flag is

         disabled. If you want to create both shared and static

         binaries, configure and compile Tix twice.

    <li> ET support is replaced by SAM (stand-alone module)

         support.

    <li> The following options are removed from configure:

         <ul>

           <li> -enable-tk40_et

           <li> -enable-tk41_et

           <li> -enable-tk41_shared

         </ul>

    <li> The new options are added to configure:

         <ul>

           <li> -enable-tk40-sam

           <li> -enable-tk41-sam

           <li> -enable-tk42-sam

           <li> -enable-tk41-shared

           <li> -enable-tk42-shared

         </ul>

  </ul>

<h4>11/1/96</h4>

  <b>New feature:</b> XPM code has been rewritten. The code is now cleanly

  separated into three modules: generic, windows specific and Unix specific.

  <p>

<h4>11/17/96</h4>

  <b>New feature:</b> Tix classes can be defined before their

  superclasses are defined. However, a class <b>cannot</b> be

  instantiated before all of its superclasses are defined. This

  feature makes it possible to load the Tix scripts into the SAM in

  any order, without having to worry about loading the superclasses

  before the subclasses. <p>

  <b>New feature:</b> Tix is initialized by calling the command

  <b>__tixInit</b>, not by sourcing <b>Init.tcl</b>. <p>

<h4>11/29/96</h4>

  <b>Bug Fixed:</b> tixTmpLine now correctly works on multiple X

  displays. <p>

<h4>11/30/96</h4>

  <b>Feature Change</b>: DisplayStyle now uses a hash table to store

  the items associated with it (previously a link list was used). This

  speeds up the delete operations when a lot (1000 or more) of items

  are associated with the same style. <b>Possible Incompatibility:</b>

  widgets that use DItems must be recompiled. <p>

  <b>Bug Fixed:</b> Tix no longer tempers with the way Tk handles

  errors, unless the environment variable TIX_DEBUG_INTERACTIVE is

  set. If this variable is set, all error messages will be printed to

  the standard output. This may be convenient for debugging

  purposes. Use this feature with discretion, and during program

  development only. <p>

<h4>12/2/96</h4>

  <b>Bug Fixed:</b>Dotted anchor lines (HList, TList, Grid) and

  rubber-band lines (PanedWindow, ResizeHandle) are implemented on Windows.<p>

  <b>New feature:</b> Tcl 7.6 support is complete for the Windows

  platform. makefile.vc and makefile.bc have been modified such that

  the Tcl version can be chosen at compile time by, e.g., "<b>make

  TCL_VER=7.5 -f makefile.bc</b>". <p>

<h4>12/2/96</h4>

  <b>Bug Fixed:</b> Display items are correctly clipped. E.g., if a

  text item is wider than the width of a column in an HList, the item

  will be clipped.<p>

<h4>12/20/96</h4>

  <b>New feature:</b> New sample file demos/samples/EditGrid.tcl that

  demonstrates the use of an editable grid widget. <p>

<h4>12/21/96</h4>

  <b>Bug Fixed:</b> Tix works with multiple interpreters under tk4.1

  and 4.2 (see test/general/minterp.tcl). However, minterp.tcl still

  core dumps under Itcl 2.1. It is not clear to me whether this is a

  problem of Tix or Itcl. <p>

  <b>Bug Fixed:</b> Now when an interpreter is deleted, all Tix class

  informations associated with this interpreter are freed. (No memory

  leak is recorded by purify when running Tix against the complete

  test suite.) <p>
