Detailed Description
Iconloader for KDE.
KIconLoader will load the current icon theme and all its base themes. Icons will be searched in any of these themes. Additionally, it caches icons and applies effects according to the user's preferences.
In KDE, it is encouraged to load icons by "Group". An icon group is a location on the screen where icons are being used. Standard groups are: Desktop, Toolbar, MainToolbar, Small and Panel. Each group has some centrally configured properties bound to it, including the icon size and effects. This makes it possible to offer a consistent icon look in all KDE applications.
The standard groups are defined below.
- KIconLoader::Desktop: Icons in the iconview of konqueror, kdesktop and similar apps.
- KIconLoader::Toolbar: Icons in toolbars.
- KIconLoader::MainToolbar: Icons in the main toolbars.
- KIconLoader::Small: Various small (typical 16x16) places: titlebars, listviews and menu entries.
- KIconLoader::Panel: Icons in kicker's panel
The icons are stored on disk in an icon theme or in a standalone directory. The icon theme directories contain multiple sizes and/or depths for the same icon. The iconloader will load the correct one based on the icon group and the current theme. Icon themes are stored globally in share/icons, or, application specific in share/apps/$appdir/icons.
The standalone directories contain just one version of an icon. The directories that are searched are: $appdir/pics and $appdir/toolbar. Icons in these directories can be loaded by using the special group "User".

Constructor & Destructor Documentation
|
explicit |
Constructs an iconloader.
- Parameters:
-
appname Add the data directories of this application to the icon search path for the "User" group. The default argument adds the directories of the current application. dirs the KStandardDirs object to use. If null the global one is used
Usually, you use the default iconloader, which can be accessed via KIconLoader::global(), so you hardly ever have to create an iconloader object yourself. That one is the current KComponentData's (typically KApplication's) iconloader.

Member Function Documentation
void KIconLoader::addAppDir | ( | const QString & | appname | ) |
Adds appname
to the list of application specific directories.
- Parameters:
-
appname The application name.
Definition at line 561 of file kiconloader.cpp.

It will try very hard to find an icon which is suitable. If no exact match is found, a close match is searched. If neither an exact nor a close match is found, a null pixmap or the "unknown" pixmap is returned, depending on the value of the canReturnNull
parameter.
- Parameters:
-
name The name of the icon, without extension. group The icon group. This will specify the size of and effects to be applied to the icon. size If nonzero, this overrides the size specified by group
. See KIconLoader::StdSizes.state The icon state: DefaultState
,ActiveState
orDisabledState

is unaltered even if the "unknown" pixmap was returned.canReturnNull Can return a null pixmap? If false, the "unknown" pixmap is returned when no appropriate icon has been found. Note: a null pixmap can still be returned in the event of invalid parameters, such as empty names, negative sizes, and etc.
- Returns:
- the QPixmap. Can be null when not found, depending on
canReturnNull

Loading itself is done by calling loadIcon .
- Parameters:
-
name The name of the icon, without extension. group The icon group. This will specify the size of and effects to be applied to the icon. size If nonzero, this overrides the size specified by group
. See KIconLoader::StdSizes.canReturnNull Can return a null iconset? If false, iconset containing the "unknown" pixmap is returned when no appropriate icon has been found.
