Sets our main struct and passes it to the parent class
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.
Creates a copy of source; mostly useful for language bindings.
Frees a dynamically-allocated icon source, along with its filename, size, and pixbuf fields if those are not NULL.
Obtains the text direction this icon source applies to. The return value is only useful/meaningful if the text direction is not wildcarded.
Gets the value set by gtk_icon_source_set_direction_wildcarded().
Retrieves the source filename, or NULL if none is set. The filename is not a copy, and should not be modified or expected to persist beyond the lifetime of the icon source.
Retrieves the source icon name, or NULL if none is set. The icon_name is not a copy, and should not be modified or expected to persist beyond the lifetime of the icon source.
Retrieves the source pixbuf, or NULL if none is set. In addition, if a filename source is in use, this function in some cases will return the pixbuf from loaded from the filename. This is, for example, true for the GtkIconSource passed to the GtkStyle::render_icon() virtual function. The reference count on the pixbuf is not incremented.
Obtains the icon size this source applies to. The return value is only useful/meaningful if the icon size is not wildcarded.
Gets the value set by gtk_icon_source_set_size_wildcarded().
Obtains the widget state this icon source applies to. The return value is only useful/meaningful if the widget state is not wildcarded.
Gets the value set by gtk_icon_source_set_state_wildcarded().
the main Gtk struct as a void*
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.
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.
Sets the name of an image file to use as a base image when creating icon variants for GtkIconSet. The filename must be absolute.
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.
Sets a pixbuf to use as a base image when creating icon variants for GtkIconSet.
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.
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.
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.
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.
the main Gtk struct
Description Browse the available stock icons in the list of stock IDs found here. You can also use the gtk-demo application for this purpose. 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.
