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

Tk::Listbox

now returns an array reference in scalar context. This means you have to write

​        my(@selected) = $listbox−>curselection

​        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

−activestyle

itemconfigure

and
