Implemented Interfaces

GtkIconFactory implements GtkBuildable.

Includes

#include <gtk/gtk.h>

Description

An icon factory manages a collection of GtkIconSet; a GtkIconSet manages a set of variants of a particular icon (i.e. a GtkIconSet contains variants for different sizes and widget states). Icons in an icon factory are named by a stock ID, which is a simple string identifying the icon. Each GtkStyle has a list of GtkIconFactory derived from the current theme; those icon factories are consulted first when searching for an icon. If the theme doesn’t set a particular icon, GTK+ looks for the icon in a list of default icon factories, maintained by gtk_icon_factory_add_default() and gtk_icon_factory_remove_default(). Applications with icons should add a default icon factory with their icons, which will allow themes to override the icons for the application.

To display an icon, always use gtk_style_lookup_icon_set() on the widget that will display the icon, or the convenience function gtk_widget_render_icon(). These functions take the theme into account when looking up the icon to use for a given stock ID.

GtkIconFactory as GtkBuildable

GtkIconFactory supports a custom <sources> element, which can contain multiple <source> elements. The following attributes are allowed:

  • stock-id

    The stock id of the source, a string. This attribute is mandatory

  • filename

    The filename of the source, a string. This attribute is optional

  • icon-name

    The icon name for the source, a string. This attribute is optional.

  • size

    Size of the icon, a GtkIconSize enum value. This attribute is optional.

  • direction

    Direction of the source, a GtkTextDirection enum value. This attribute is optional.

  • state

    State of the source, a GtkStateType enum value. This attribute is optional.

Functions

gtk_icon_source_copy ()

GtkIconSource *
gtk_icon_source_copy (const GtkIconSource *source);

gtk_icon_source_copy has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Creates a copy of source ; mostly useful for language bindings.

Parameters

source

a GtkIconSource

 

Returns

a new GtkIconSource


gtk_icon_source_free ()

void
gtk_icon_source_free (GtkIconSource *source);

gtk_icon_source_free has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Frees a dynamically-allocated icon source, along with its filename, size, and pixbuf fields if those are not NULL.

Parameters

source

a GtkIconSource

 

gtk_icon_factory_add ()

void
gtk_icon_factory_add (GtkIconFactory *factory,
                      const gchar *stock_id,
                      GtkIconSet *icon_set);

gtk_icon_factory_add has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Adds the given icon_set to the icon factory, under the name stock_id . stock_id should be namespaced for your application, e.g. “myapp-whatever-icon”. Normally applications create a GtkIconFactory, then add it to the list of default factories with gtk_icon_factory_add_default(). Then they pass the stock_id to widgets such as GtkImage to display the icon. Themes can provide an icon with the same name (such as "myapp-whatever-icon") to override your application’s default icons. If an icon already existed in factory for stock_id , it is unreferenced and replaced with the new icon_set .

Parameters

factory

a GtkIconFactory

 

stock_id

icon name

 

icon_set

icon set

 

gtk_icon_factory_add_default ()

void
gtk_icon_factory_add_default (GtkIconFactory *factory);

gtk_icon_factory_add_default has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Adds an icon factory to the list of icon factories searched by gtk_style_lookup_icon_set(). This means that, for example, gtk_image_new_from_stock() will be able to find icons in factory . There will normally be an icon factory added for each library or application that comes with icons. The default icon factories can be overridden by themes.

Parameters

factory

a GtkIconFactory

 

gtk_icon_factory_lookup ()

GtkIconSet *
gtk_icon_factory_lookup (GtkIconFactory *factory,
                         const gchar *stock_id);

gtk_icon_factory_lookup has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Looks up stock_id in the icon factory, returning an icon set if found, otherwise NULL. For display to the user, you should use gtk_style_lookup_icon_set() on the GtkStyle for the widget that will display the icon, instead of using this function directly, so that themes are taken into account.

Parameters

factory

a GtkIconFactory

 

stock_id

an icon name

 

Returns

icon set of stock_id .

[transfer none]


gtk_icon_factory_lookup_default ()

GtkIconSet *
gtk_icon_factory_lookup_default (const gchar *stock_id);

gtk_icon_factory_lookup_default has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Looks for an icon in the list of default icon factories. For display to the user, you should use gtk_style_lookup_icon_set() on the GtkStyle for the widget that will display the icon, instead of using this function directly, so that themes are taken into account.

Parameters

stock_id

an icon name

 

Returns

a GtkIconSet, or NULL.

[transfer none]


gtk_icon_factory_new ()

GtkIconFactory *
gtk_icon_factory_new (void);

gtk_icon_factory_new has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Creates a new GtkIconFactory. An icon factory manages a collection of GtkIconSets; a GtkIconSet manages a set of variants of a particular icon (i.e. a GtkIconSet contains variants for different sizes and widget states). Icons in an icon factory are named by a stock ID, which is a simple string identifying the icon. Each GtkStyle has a list of GtkIconFactorys derived from the current theme; those icon factories are consulted first when searching for an icon. If the theme doesn’t set a particular icon, GTK+ looks for the icon in a list of default icon factories, maintained by gtk_icon_factory_add_default() and gtk_icon_factory_remove_default(). Applications with icons should add a default icon factory with their icons, which will allow themes to override the icons for the application.

Returns

a new GtkIconFactory


gtk_icon_factory_remove_default ()

void
gtk_icon_factory_remove_default (GtkIconFactory *factory);

gtk_icon_factory_remove_default has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Removes an icon factory from the list of default icon factories. Not normally used; you might use it for a library that can be unloaded or shut down.

Parameters

factory

a GtkIconFactory previously added with gtk_icon_factory_add_default()

 

gtk_icon_set_add_source ()

void
gtk_icon_set_add_source (GtkIconSet *icon_set,
                         const GtkIconSource *source);

gtk_icon_set_add_source has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Icon sets have a list of GtkIconSource, which they use as base icons for rendering icons in different states and sizes. Icons are scaled, made to look insensitive, etc. in gtk_icon_set_render_icon(), but GtkIconSet needs base images to work with. The base images and when to use them are described by a GtkIconSource.

This function copies source , so you can reuse the same source immediately without affecting the icon set.

An example of when you’d use this function: a web browser’s "Back to Previous Page" icon might point in a different direction in Hebrew and in English; it might look different when insensitive; and it might change size depending on toolbar mode (small/large icons). So a single icon set would contain all those variants of the icon, and you might add a separate source for each one.

You should nearly always add a “default” icon source with all fields wildcarded, which will be used as a fallback if no more specific source matches. GtkIconSet always prefers more specific icon sources to more generic icon sources. The order in which you add the sources to the icon set does not matter.

gtk_icon_set_new_from_pixbuf() creates a new icon set with a default icon source based on the given pixbuf.

Parameters

icon_set

a GtkIconSet

 

source

a GtkIconSource

 

gtk_icon_set_copy ()

GtkIconSet *
gtk_icon_set_copy (GtkIconSet *icon_set);

gtk_icon_set_copy has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Copies icon_set by value.

Parameters

icon_set

a GtkIconSet

 

Returns

a new GtkIconSet identical to the first.


gtk_icon_set_new ()

GtkIconSet *
gtk_icon_set_new (void);

gtk_icon_set_new has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Creates a new GtkIconSet. A GtkIconSet represents a single icon in various sizes and widget states. It can provide a GdkPixbuf for a given size and state on request, and automatically caches some of the rendered GdkPixbuf objects.

Normally you would use gtk_widget_render_icon_pixbuf() instead of using GtkIconSet directly. The one case where you’d use GtkIconSet is to create application-specific icon sets to place in a GtkIconFactory.

Returns

a new GtkIconSet


gtk_icon_set_new_from_pixbuf ()

GtkIconSet *
gtk_icon_set_new_from_pixbuf (GdkPixbuf *pixbuf);

gtk_icon_set_new_from_pixbuf has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Creates a new GtkIconSet with pixbuf as the default/fallback source image. If you don’t add any additional GtkIconSource to the icon set, all variants of the icon will be created from pixbuf , using scaling, pixelation, etc. as required to adjust the icon size or make the icon look insensitive/prelighted.

Parameters

pixbuf

a GdkPixbuf

 

Returns

a new GtkIconSet


gtk_icon_set_ref ()

GtkIconSet *
gtk_icon_set_ref (GtkIconSet *icon_set);

gtk_icon_set_ref has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Increments the reference count on icon_set .

Parameters

icon_set

a GtkIconSet.

 

Returns

icon_set .


gtk_icon_set_render_icon ()

                          GtkStyle *style,
                          GtkTextDirection direction,
                          GtkStateType state,
                          GtkIconSize size,
                          GtkWidget *widget,
                          const gchar *detail);

gtk_icon_set_render_icon has been deprecated since version 3.0 and should not be used in newly-written code.

Use gtk_icon_set_render_icon_pixbuf() instead

Renders an icon using gtk_style_render_icon(). In most cases, gtk_widget_render_icon() is better, since it automatically provides most of the arguments from the current widget settings. This function never returns NULL; if the icon can’t be rendered (perhaps because an image file fails to load), a default "missing image" icon will be returned instead.

Parameters

icon_set

a GtkIconSet

 

style

a GtkStyle associated with widget , or NULL.

[allow-none]

direction

text direction

 

state

widget state

 

size

icon size (GtkIconSize). A size of (GtkIconSize)-1 means render at the size of the source and don’t scale.

[type int]

widget

widget that will display the icon, or NULL. The only use that is typically made of this is to determine the appropriate GdkScreen.

[allow-none]

detail

detail to pass to the theme engine, or NULL. Note that passing a detail of anything but NULL will disable caching.

[allow-none]

Returns

a GdkPixbuf to be displayed.

                      gint *height);

Obtains the pixel size of a semantic icon size size : GTK_ICON_SIZE_MENU, GTK_ICON_SIZE_BUTTON, etc. This function isn’t normally needed, gtk_icon_theme_load_icon() is the usual way to get an icon for rendering, then just look at the size of the rendered pixbuf. The rendered pixbuf may not even correspond to the width/height returned by gtk_icon_size_lookup(), because themes are free to render the pixbuf however they like, including changing the usual size.

Parameters

size

an icon size (GtkIconSize).

[type int]

width

location to store icon width.

[out][allow-none]

height

gtk_icon_size_lookup_for_settings has been deprecated since version 3.10 and should not be used in newly-written code.

Use gtk_icon_size_lookup() instead.

Obtains the pixel size of a semantic icon size, possibly modified by user preferences for a particular GtkSettings. Normally size would be GTK_ICON_SIZE_MENU, GTK_ICON_SIZE_BUTTON, etc. This function isn’t normally needed, gtk_widget_render_icon_pixbuf() is the usual way to get an icon for rendering, then just look at the size of the rendered pixbuf. The rendered pixbuf may not even correspond to the width/height returned by gtk_icon_size_lookup(), because themes are free to render the pixbuf however they like, including changing the usual size.

Parameters

settings

a GtkSettings object, used to determine which set of user preferences to used.

 

size

an icon size (GtkIconSize).

[type int]

gtk_icon_source_get_state has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Obtains the widget state this icon source applies to. The return value is only useful/meaningful if the widget state is not wildcarded.

Parameters

source

a GtkIconSource

 

Returns

widget state this source matches


gtk_icon_source_get_state_wildcarded ()

gboolean
gtk_icon_source_get_state_wildcarded (const GtkIconSource *source);

gtk_icon_source_get_state_wildcarded has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Gets the value set by gtk_icon_source_set_state_wildcarded().

Parameters

source

a GtkIconSource

 

Returns

TRUE if this icon source is a base for any widget state variant


gtk_icon_source_new ()

GtkIconSource *
gtk_icon_source_new (void);

gtk_icon_source_new has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Creates a new GtkIconSource. A GtkIconSource contains a GdkPixbuf (or image filename) that serves as the base image for one or more of the icons in a GtkIconSet, along with a specification for which icons in the icon set will be based on that pixbuf or image file. An icon set contains a set of icons that represent “the same” logical concept in different states, different global text directions, and different sizes.

So for example a web browser’s “Back to Previous Page” icon might point in a different direction in Hebrew and in English; it might look different when insensitive; and it might change size depending on toolbar mode (small/large icons). So a single icon set would contain all those variants of the icon. GtkIconSet contains a list of GtkIconSource from which it can derive specific icon variants in the set.

In the simplest case, GtkIconSet contains one source pixbuf from which it derives all variants. The convenience function gtk_icon_set_new_from_pixbuf() handles this case; if you only have one source pixbuf, just use that function.

If you want to use a different base pixbuf for different icon variants, you create multiple icon sources, mark which variants they’ll be used to create, and add them to the icon set with gtk_icon_set_add_source().

By default, the icon source has all parameters wildcarded. That is, the icon source will be used as the base icon for any desired text direction, widget state, or icon size.

Returns

a new GtkIconSource


gtk_icon_source_set_direction ()

void
gtk_icon_source_set_direction (GtkIconSource *source,
                               GtkTextDirection direction);

gtk_icon_source_set_direction has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Sets the text direction this icon source is intended to be used with.

Setting the text direction on an icon source makes no difference if the text direction is wildcarded. Therefore, you should usually call gtk_icon_source_set_direction_wildcarded() to un-wildcard it in addition to calling this function.

Parameters

source

a GtkIconSource

 

direction

text direction this source applies to

 

gtk_icon_source_set_direction_wildcarded ()

void
gtk_icon_source_set_direction_wildcarded
                               (GtkIconSource *source,
                                gboolean setting);

gtk_icon_source_set_direction_wildcarded has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

If the text direction is wildcarded, this source can be used as the base image for an icon in any GtkTextDirection. If the text direction is not wildcarded, then the text direction the icon source applies to should be set with gtk_icon_source_set_direction(), and the icon source will only be used with that text direction.

GtkIconSet prefers non-wildcarded sources (exact matches) over wildcarded sources, and will use an exact match when possible.

Parameters

source

a GtkIconSource

 

setting

TRUE to wildcard the text direction

 

gtk_icon_source_set_filename ()

void
gtk_icon_source_set_filename (GtkIconSource *source,
                              const gchar *filename);

gtk_icon_source_set_filename has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Sets the name of an image file to use as a base image when creating icon variants for GtkIconSet. The filename must be absolute.

Parameters

source

a GtkIconSource

 

filename

image file to use.

[type filename]

gtk_icon_source_set_pixbuf ()

void
gtk_icon_source_set_pixbuf (GtkIconSource *source,
                            GdkPixbuf *pixbuf);

gtk_icon_source_set_pixbuf has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Sets a pixbuf to use as a base image when creating icon variants for GtkIconSet.

Parameters

source

a GtkIconSource

 

pixbuf

pixbuf to use as a source

 

gtk_icon_source_set_icon_name ()

void
gtk_icon_source_set_icon_name (GtkIconSource *source,
                               const gchar *icon_name);

gtk_icon_source_set_icon_name has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Sets the name of an icon to look up in the current icon theme to use as a base image when creating icon variants for GtkIconSet.

Parameters

source

a GtkIconSource

 

icon_name

name of icon to use.

[allow-none]

gtk_icon_source_set_size ()

void
gtk_icon_source_set_size (GtkIconSource *source,
                          GtkIconSize size);

gtk_icon_source_set_size has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Sets the icon size this icon source is intended to be used with.

Setting the icon size on an icon source makes no difference if the size is wildcarded. Therefore, you should usually call gtk_icon_source_set_size_wildcarded() to un-wildcard it in addition to calling this function.

Parameters

source

a GtkIconSource

 

size

icon size (GtkIconSize) this source applies to.

[type int]

gtk_icon_source_set_size_wildcarded ()

void
gtk_icon_source_set_size_wildcarded (GtkIconSource *source,
                                     gboolean setting);

gtk_icon_source_set_size_wildcarded has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

If the icon size is wildcarded, this source can be used as the base image for an icon of any size. If the size is not wildcarded, then the size the source applies to should be set with gtk_icon_source_set_size() and the icon source will only be used with that specific size.

GtkIconSet prefers non-wildcarded sources (exact matches) over wildcarded sources, and will use an exact match when possible.

GtkIconSet will normally scale wildcarded source images to produce an appropriate icon at a given size, but will not change the size of source images that match exactly.

Parameters

source

a GtkIconSource

 

setting

TRUE to wildcard the widget state

 

gtk_icon_source_set_state ()

void
gtk_icon_source_set_state (GtkIconSource *source,
                           GtkStateType state);

gtk_icon_source_set_state has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

Sets the widget state this icon source is intended to be used with.

Setting the widget state on an icon source makes no difference if the state is wildcarded. Therefore, you should usually call gtk_icon_source_set_state_wildcarded() to un-wildcard it in addition to calling this function.

Parameters

source

a GtkIconSource

 

state

widget state this source applies to

 

gtk_icon_source_set_state_wildcarded ()

void
gtk_icon_source_set_state_wildcarded (GtkIconSource *source,
                                      gboolean setting);

gtk_icon_source_set_state_wildcarded has been deprecated since version 3.10 and should not be used in newly-written code.

Use GtkIconTheme instead.

If the widget state is wildcarded, this source can be used as the base image for an icon in any GtkStateType. If the widget state is not wildcarded, then the state the source applies to should be set with gtk_icon_source_set_state() and the icon source will only be used with that specific state.

GtkIconSet prefers non-wildcarded sources (exact matches) over wildcarded sources, and will use an exact match when possible.

GtkIconSet will normally transform wildcarded source images to produce an appropriate icon for a given state, for example lightening an image on prelight, but will not modify source images that match exactly.

Parameters

source

a GtkIconSource

 

setting

TRUE to wildcard the widget state
