[TYPO3-core] RFC #14785: add feature: Add HOOKS to class.t3lib_iconworks.php for developing alternative backend-skins!

[Stephan N Kellermayr]

this is an SVN patch request.

type: feature

bugtracker references:
http://bugs.typo3.org/view.php?id=14785

branches:
trunk/current branch


problem:
at the moment there is no possibility to extend the class 
't3lib_iconworks', which is very bad for redesigning the backend, 
because you stuck on the implemented functions which handles the sprites 
and icons.

there are so many possibilities to handle those icons, and to stay 
flexible in visualization, there should also be the possibility to 
implement other ways of icon-handling or extend the functionallity of 
the current sprite-concept.

why this is needed?
example1: if you want to generate different names for the base-icons, 
depending on different db-columns than the defaults.
example2: if you want to add (sub)classes to overlays or base-icons, 
useful if you want to use a sprite-matrix!
...

solution:
because XCLASS is not a good idea at this point, please add the 
following patch to t3lib_iconWorks, which provides three hooks for the 
critical functions.
(patch attached: t3lib/class.t3lib_iconworks.php.0014785.diff)


notes:
i will soon release an extension, which is basically a skincreator for 
t3xskin, but also gives you the possibility to create 
sprites/spritematrix for own extensions, complete with tutorials, 
photoshop-templates and colormanager, and automatic integration into TYPO3.
in this example you will see, how this functions could work, to give 
users a fulfilling TYPO3-experience!
no worries, i will stay as close as possible at the naming-convention 
which are currently used and i will NOT confuse the whole thing again.
...and yes, i will still use only ONE single overlay and use a 
spritematrix instead ;-)


best regards,
Stephan N Kellermayr
