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

       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

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

	       my(@selected) = $listbox->curselection


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


       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.

       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
	   An alternative to Tk::LabFrame.
