Detailed Description

The usual place to look for assets is Qt's AppDataLocation. This corresponds to XDG_DATA_DIRS on Linux. To ensure your installation and path are configured correctly, ensure your files are located in the directories contained in this variable:

QStandardPaths::standardLocations(QStandardPaths::AppDataLocation);

This can be overridden in Krita's configuration.

Unfortunately, we are mixing up two things in the appdatalocation:

• resources: brushes, presets and so on
• assets: color themes, icc profiles and other weird stuff

There are many debug lines that can be uncommented for more specific installation checks. In the future these should be converted to qloggingcategory to enable convenient enable/disable functionality.

Note: DO NOT USE THIS CLASS WHEN LOCATING RESOURCES LIKE BRUSHES OR GRADIENTS. Use KisResourceLocator instead.

addAssetDir()

void KoResourcePaths::addAssetDir ( const QString & type, const QString & dir, bool priority = true )

static

Adds absolute path at the beginning 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.

Parameters

type	Specifies a short descriptive string to access files of this type.
absdir	Points to directory where to look for this specific type. Nonexistent directories may be saved but pruned.
priority	if true, the directory is added before any other, otherwise after

Definition at line 345 of file KoResourcePaths.cpp.

{
    s_instance->addResourceDirInternal(type, dir, priority);
}

addAssetType()

void KoResourcePaths::addAssetType ( const QString & type, const char * basetype, const QString & relativeName, bool priority = true )

static

Adds suffixes for asset types.

You may add as many as you need, but it is advised that there is exactly one to make writing definite.

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 KoStandardPaths::addResourceType("app_pics", "data", "app/pics");

Parameters

type	Specifies a short descriptive string to access files of this type.
basetype	Specifies an already known type, or 0 if none
relativename	Specifies a directory relative to the basetype
priority	if true, the directory is added before any other, otherwise after

assetDirs()

QStringList KoResourcePaths::assetDirs ( const QString & type )

static

Parameters

type	The type of resource

Returns

The list of possible directories for the specified type. The function updates the cache if possible. If the resource type specified is unknown, it will return an empty list. Note, that the directories are assured to exist beside the save location, which may not exist, but is returned anyway.

findAllAssets()

QStringList KoResourcePaths::findAllAssets ( const QString & type, const QString & filter = QString(), SearchOptions options = NoSearchOptions )

static

Tries to find all resources with the specified type.

The function will look into all specified directories and return all filenames in these directories.

The "most local" files are returned before the "more global" files.

Parameters

type	The type of resource to locate directories for.
filter	Only accept filenames that fit to filter. The filter may consist of an optional directory and a QRegExp wildcard expression. E.g. "images\*.jpg". Use QString() if you do not want a filter.
options	if the flags passed include Recursive, subdirectories will also be search.

Returns

List of all the files whose filename matches the specified filter.

findAsset()

QString KoResourcePaths::findAsset ( const QString & type, const QString & fileName )

static

Tries to find a resource in the following order:

• All PREFIX/<relativename> paths (most recent first).
• All absolute paths (most recent first).

The filename should be a filename relative to the base dir for resources. So it's a way to get the path to libkdecore.la to findResource("lib", "libkdecore.la"). KStandardDirs will then look into the subdir lib of all elements of all prefixes ($KDEDIRS) for a file libkdecore.la and return the path to the first one it finds (e.g. /opt/kde/lib/libkdecore.la).

Example:

QString iconfilename = KStandardPaths::findResource("icon",QString("oxygen/22x22/apps/ktip.png"));

Parameters

type	The type of the wanted resource
filename	A relative filename of the resource.

Returns

A full path to the filename specified in the second argument, or QString() if not found.

{
    return cleanup(s_instance->findResourceInternal(type, fileName));
}

findDirs()

QStringList KoResourcePaths::findDirs ( const QString & type )

static

Tries to find all directories whose names consist of the specified type and a relative path. So findDirs("xdgdata-apps", "Settings") would return

• /home/joe/.local/share/applications/Settings/
• /usr/share/applications/Settings/

(from the most local to the most global)

Note that it appends / to the end of the directories, so you can use this right away as directory names.

Parameters

type	The type of the base directory.
reldir	Relative directory.

Returns

A list of matching directories, or an empty list if the resource specified is not found.

locate()

QString KoResourcePaths::locate ( const QString & type, const QString & filename )

static

This function is just for convenience. It simply calls KoResourcePaths::findResource((type, filename).

Parameters

type	The type of the wanted resource, see KStandardDirs
filename	A relative filename of the resource

Returns

A full path to the filename specified in the second argument, or QString() if not found

locateLocal()

QString KoResourcePaths::locateLocal ( const QString & type, const QString & filename, bool createDir = false )

static

This function is much like locate. However it returns a filename suitable for writing to. No check is made if the specified filename actually exists. Missing directories are created. If filename is only a directory, without a specific file, filename must have a trailing slash.

Parameters

type	The type of the wanted resource, see KStandardDirs
filename	A relative filename of the resource

Returns

A full path to the filename specified in the second argument, or QString() if not found

Definition at line 382 of file KoResourcePaths.cpp.

saveLocation()

QString KoResourcePaths::saveLocation ( const QString & type, const QString & suffix = QString(), bool create = true )

static

Finds a location to save files into for the given type in the user's home directory.

Parameters

type	The type of location to return.
suffix	A subdirectory name. Makes it easier for you to create subdirectories. You can't pass filenames here, you have to pass directory names only and add possible filename in that directory yourself. A directory name always has a trailing slash ('/').
create	If set, saveLocation() will create the directories needed (including those given by suffix).

Returns

A path where resources of the specified type should be saved, or QString() if the resource type is unknown.
