All icon themes currently delivered with qooxdoo are generated from some original open-source icon themes. The basic steps to include an existing icon theme (e.g. from KDE or Gnome) into qooxdoo (which follows the Freedesktop Icon Naming Specification) are:

• Converting original names (e.g. KDE → Freedesktop, Gnome → Freedesktop, …)
• Generating a whitelist
• Copying common icons which are mentioned in the whitelist to a qooxdoo icon folder.

The relevant tools and resources are available inside framework/tool/icon, where you should find the following scripts:

• [a] freedesktop-to-qooxdoo.sh: Use the user-supplied whitelist to copy the icons themes of freedesktop/use to qooxdoo/use.
• [b] generate-whitelist.sh: Create a whitelist of the common icons inside freedesktop/use. This whitelist is used by [a].
• [c] kde-to-freedesktop.sh: Convert KDE icon themes using the mapping defined by data/kde_freedesktop.dat. Generally this only copies some of the available images. (Many icons in KDE have no match in the current freedesktop specification).
• [d] normalize-kde-themes.sh: Normalize KDE themes in kde/use. This corrects some names of icons using symlinks.
• [e] prepare-kde-themes.sh: Check the icons which exist in kde/use against the mapping in data/kde_freedesktop.dat.
• [f] scaleable-to-png.sh: Convert SVG images to the various supported icon sizes by rendering them.

Please be sure to execute all scripts after you have changed your current working directory:

cd framework/tool/icon

The typical process to add a new theme (in this example a KDE theme) to qooxdoo is:

• Copy KDE theme(s) to kde/use and/or copy Freedesktop themes to freedesktop/use. Put SVG themes into freedesktop/scalable instead.
• Execute [d]
• Execute [e] and check the output for missing images.
• Execute [c] to convert KDE themes
• Convert SVG freedesktop themes using [f]
• Finally use [b] to update the whitelist. Important note: Please make sure that the whitelist does not remove previously existing icons by issuing the following command: svn diff data/qooxdoo_whitelist.dat. Otherwise, you would need migration support.
• Execute [a] to create a icon theme copy for qooxdoo.
• Sync the icons of qooxdoo/use to framework/source/resource/icon and update the README there.
