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->curselectionor
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>>.
