To this end it insulates the application from all information and applications always refer to a file with a resource type (e.g. icon) and a filename (e.g. khexdit.xpm). In an ideal world the application would make no assumption where this file is and leave it up to KStandardDirs::findResource("apps", "Home.desktop") to apply this knowledge to return /opt/kde/share/applnk/Home.desktop or ::locate("data", "kgame/background.jpg") to return /opt/kde/share/apps/kgame/background.jpg
The main idea behind KStandardDirs is that there are several toplevel prefixes below which the files lie. One of these prefixes is the one where the user installed kdelibs, one is where the application was installed, and one is $HOME/.kde, but there may be even more. Under these prefixes there are several well defined suffixes where specific resource types are to be found. For example, for the resource type "html" the suffixes could be share/doc/HTML and share/doc/kde/HTML. So the search algorithm basically appends to each prefix each registered suffix and tries to locate the file there. To make the thing even more complex, it's also possible to register absolute paths that KStandardDirs looks up after not finding anything in the former steps. They can be useful if the user wants to provide specific directories that aren't in his $HOME/.kde directory for, for example, icons.
Standard resources that kdelibs allocates are:
- apps - Applications menu (.desktop files).
- cache - Cached information (e.g. favicons, web-pages)
- cgi - CGIs to run from kdehelp.
- config - Configuration files.
- data - Where applications store data.
- exe - Executables in $prefix/bin. findExe() for a function that takes $PATH into account.
- html - HTML documentation.
- icon - Icons, see KIconLoader.
- lib - Libraries.
- locale - Translation files for KLocale.
- mime - Mime types.
- module - Module (dynamically loaded library).
- qtplugins - Qt plugins (dynamically loaded objects for Qt)
- services - Services.
- servicetypes - Service types.
- scripts - Application scripting additions.
- sound - Application sounds.
- templates - Templates
- wallpaper - Wallpapers.
- tmp - Temporary files (specific for both current host and current user)
- socket - UNIX Sockets (specific for both current host and current user)
KStandardDirs supports the following environment variables:
- KDEDIRS: This may set an additional number of directory prefixes to search for resources. The directories should be separated by ':'. The directories are searched in the order they are specified.
- KDEDIR: Used for backwards compatibility. As KDEDIRS but only a single directory may be specified. If KDEDIRS is set KDEDIR is ignored.
- KDEHOME: The directory where changes are saved to. This directory is used to search for resources first. If KDEHOME is not specified it defaults to "$HOME/.kde"
- KDEROOTHOME: Like KDEHOME, but used for the root user. If KDEROOTHOME is not set it defaults to the .kde directory in the home directory of root, usually "/root/.kde". Note that the setting of $HOME is ignored in this case.

Adds another search dir to front of the XDG_CONFIG_XXX list of prefixes. This prefix is only used for resources that start with "xdgconf-"

Adds another search dir to front of the XDG_DATA_XXX list of prefixes. This prefix is only used for resources that start with "xdgdata-"

Adds suffixes for types. You may add as many as you need, but it is advised that there is exactly one to make writing definite. All basic types ( kde_default) are added by addKDEDefaults(), but for those you can add more relative paths as well. The later a suffix is added, the higher its priority. Note, that the suffix should end with / but doesn't have to start with one (as prefixes should end with one). So adding a suffix for app_pics would look like KGlobal::dirs()->addResourceType("app_pics", "share/app/pics");

Adds absolute path at the end of the search path for particular types (for example in case of icons where the user specifies extra paths). You shouldn't need this function in 99% of all cases besides adding user-given paths.

Tries to find a resource in the following order:

|
Checks whether a resource is restricted as part of the KIOSK framework. When a resource is restricted it means that user- specific files in the resource are ignored. E.g. by restricting the "wallpaper" resource, only system-wide installed wallpapers will be found by this class. Wallpapers installed under the $KDEHOME directory will be ignored.

Returns a number that identifies this version of the resource. When a change is made to the resource this number will change.

|
Tries to find the directory the file is in. It works the same as findResource(), but it doesn't return the filename but the name of the directory. This way the application can access a couple of files that have been installed into the same directory without having to look for each file. findResourceDir("lib", "libkdecore.la") would return the path of the subdir libkdecore.la is found first in (e.g. /opt/kde/lib/)

This function adds the defaults that are used by the current KDE version. It's a series of addResourceTypes() and addPrefix() calls. You normally wouldn't call this function because it's called for you from KGlobal.
