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.
- Tk::Labelframe
- An alternative to Tk::LabFrame.
- Tk::Panedwindow
- An alternative to Tk::Adjuster.
- Tk::Spinbox
- An alternative to the CPAN module Tk::NumEntry.
