Detailed Description
Iconloader for KDE.
- Note
- For most icon loading use cases perfer using QIcon::fromTheme
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 can have some centrally-configured effects applied to its icons. 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
◆ KIconLoader()
|
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. extraSearchPaths additional search paths, either absolute or relative to GenericDataLocation
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 application's iconloader.
Definition at line 341 of file kiconloader.cpp.
◆ ~KIconLoader()
|
overridedefault |
Cleanup.
Member Function Documentation
◆ addAppDir()
Adds appname
to the list of application specific directories with themeBaseDir
as its base directory.
Assume the icons are in /home/user/app/icons/hicolor/48x48/my_app.png, the base directory would be /home/user/app/icons; KIconLoader automatically searches themeBaseDir
+ "/hicolor" This directory must contain a dir structure as defined by the XDG icons specification
- Parameters
-
appname The application name. themeBaseDir The base directory of the application's theme (eg. "/home/user/app/icons")
Definition at line 427 of file kiconloader.cpp.
