NAME
       Tk::804delta - what is new for perl/Tk 804

DESCRIPTION
       This document describes differences between the Tk800 series and the
       Tk804 series.

Incompatible Changes
       In Tk804.028, there are some additional incompatible changes:

       Return values of some Tk::Wm methods (e.g. aspect, wmGrid,
       iconposition, resizable ...) were changed from returning tclish lists
       (e.g. "1 2 3 4") to perlish lists (1,2,3,4).

       Tk::Wm::wmTracing needs argument for setting on/off, without argument
       just return the current value.

       All Tk804 releases have the following incompatible changes:

       Tk804 will only work with perl 5.8.0 and above. For older perl versions
       look for Tk800.025.

       curselection of Tk::Listbox now returns an array reference in scalar
       context. This means you have to write

               my(@selected) = $listbox->curselection

       or

               my(@selected) = @{ $listbox->curselection }

       now.

       The fontActual method now returns the pixel value instead of the point
       value for -size. Pixel values are expressed as negative numbers.

       Some enhancements from the "dash" patches are lost for now (i.e. -tile,
       -troughtile ...).

       The -state option is not available anymore for Tk::Text tags.  Use
       -elide instead.

Enhancements
       Tk804 is Unicode-aware.

       It is possible to build Tk with Xft support on X11. This is strongly
       recommened if you are planning to make use of Unicode rendering
       capabilities of Tk. It also gives anti-aliased fonts for regular text
       (if you have TrueType or Type1 fonts and they are in your fontconfig
       config file).

       The new method chooseDirectory is available as a standard directory
       selector.

       Tk::PNG and Tk::JPEG are bundled now with the perl/Tk distribution,
       providing support for the image formats png and jpeg.

       Improvements to Tk::Listbox: new option -activestyle, new methods
       itemconfigure and itemcget, new virtual event <<ListboxSelect>>.

       More tests.

New Widgets
       Tk::Labelframe
           An alternative to Tk::LabFrame.

       Tk::Panedwindow
           An alternative to Tk::Adjuster.

       Tk::Spinbox
           An alternative to the CPAN module Tk::NumEntry.
