Detailed Description

Iconloader for KDE.

TDEIconLoader 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.

TDEIcon::Desktop: Icons in the iconview of konqueror, kdesktop and similar apps.
TDEIcon::Toolbar: Icons in toolbars.
TDEIcon::MainToolbar: Icons in the main toolbars.
TDEIcon::Small: Various small (typical 16x16) places: titlebars, listviews and menu entries.
TDEIcon::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

◆ TDEIconLoader()

TDEIconLoader::TDEIconLoader	(	const TQString &	appname = `TQString::null`,
		TDEStandardDirs *	dirs = `0`
	)

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 TDEStandardDirs object to use. If null the global one is used

Usually, you use the default iconloader, which can be accessed via TDEGlobal::iconLoader(), so you hardly ever have to create an iconloader object yourself. That one is the current TDEInstance's (typically TDEApplication's) iconloader.

See also: TDEGlobal::iconLoader(); TDEInstance::iconLoader()

Definition at line 134 of file kiconloader.cpp.

◆ ~TDEIconLoader()

TDEIconLoader::~TDEIconLoader ( )

Cleanup.

Definition at line 267 of file kiconloader.cpp.

Member Function Documentation

◆ addAppDir()

void TDEIconLoader::addAppDir ( const TQString & appname )

Adds appname to the list of application specific directories.

Parameters

appname The application name.

Definition at line 299 of file kiconloader.cpp.

◆ addExtraDesktopThemes()

void TDEIconLoader::addExtraDesktopThemes ( )

Adds all the default themes from other desktops at the end of the list of icon themes.

Since: 3.1

Definition at line 351 of file kiconloader.cpp.

◆ alphaBlending()

bool TDEIconLoader::alphaBlending ( TDEIcon::Group group ) const

Checks whether the user wants to blend the icons with the background using the alpha channel information for a given group.

Parameters

group the group to check

Returns: true if alpha blending is desired

Deprecated:

Definition at line 1130 of file kiconloader.cpp.

◆ currentSize()

int TDEIconLoader::currentSize ( TDEIcon::Group group ) const

Returns the current size of the group.

Parameters

group the group to check.

Returns: the current size for an icon group.

Definition at line 1012 of file kiconloader.cpp.

◆ enableDelayedIconSetLoading()

void TDEIconLoader::enableDelayedIconSetLoading ( bool enable )

Enables on-demand icon loading for QIconSets using TQIconFactory.

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 TDEIconLoader objects). Every TDEInstance 's iconloader has this feature enabled.

Parameters

enable true to enable delayed icon loading, false to disable

See also: isDelayedIconSetLoadingEnabled(); QIconFactory

Since: 3.1

Definition at line 289 of file kiconloader.cpp.

◆ extraDesktopThemesAdded()

Loads an animated icon as a series of still frames.

If you want to load a .mng animation as TQMovie instead, please use loadMovie() instead.

Parameters

name	The name of the icon.
group	The icon group. See loadIcon().

		bool	canReturnNull = `false`
	)		const

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 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 TDEIcon::StdSizes.
state	The icon state: `DefaultState`, `ActiveState` or `DisabledState`. Depending on the user's preferences, the iconloader may apply a visual effect to hint about its state.
path_store	If not null, the path of the icon is stored here.
canReturnNull	Can return a null pixmap? If false, the "unknown" pixmap is returned when no appropriate icon has been found.

Returns: the TQPixmap. Can be null when not found, depending on canReturnNull.
