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 the 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.
- KIcon::Desktop: Icons in the iconview of konqueror, kdesktop and similar apps.
- KIcon::Toolbar: Icons in toolbars.
- KIcon::MainToolbar: Icons in the main toolbars.
- KIcon::Small: Various small (typical 16x16) places: titlebars, listviews and menu entries.
- KIcon::Panel: Icons in kicker's panel
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".

Loads an icon.
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

|
Enables on-demand icon loading for QIconSets using QIconFactory. Icons loaded via loadIconSet() will be loaded as soon as they need to be displayed, not earlier. Note that enabling or disabling this only affects loadIconSet() calls after this setting is changed. The default is disabled, as the iconloader object must not be destroyed before all those iconsets are destroyed. (Some broken applications use temporary KIconLoader objects). Every KInstance 's iconloader has this feature enabled.

Checks whether delayed loading for QIconSet is enabled.
