| 51 | * @Short_description: Manipulating stock icons |
| 52 | * @Title: Themeable Stock Images |
| 53 | * |
| 54 | * An icon factory manages a collection of #CtkIconSet; a #CtkIconSet manages a |
| 55 | * set of variants of a particular icon (i.e. a #CtkIconSet contains variants for |
| 56 | * different sizes and widget states). Icons in an icon factory are named by a |
| 57 | * stock ID, which is a simple string identifying the icon. Each #CtkStyle has a |
| 58 | * list of #CtkIconFactory derived from the current theme; those icon factories |
| 59 | * are consulted first when searching for an icon. If the theme doesn’t set a |
| 60 | * particular icon, CTK+ looks for the icon in a list of default icon factories, |
| 61 | * maintained by ctk_icon_factory_add_default() and |
| 62 | * ctk_icon_factory_remove_default(). Applications with icons should add a default |
| 63 | * icon factory with their icons, which will allow themes to override the icons |
| 64 | * for the application. |
| 65 | * |
| 66 | * To display an icon, always use ctk_style_lookup_icon_set() on the widget that |
| 67 | * will display the icon, or the convenience function |
| 68 | * ctk_widget_render_icon(). These functions take the theme into account when |
| 69 | * looking up the icon to use for a given stock ID. |
| 70 | * |
| 71 | * # CtkIconFactory as CtkBuildable # {#CtkIconFactory-BUILDER-UI} |
| 72 | * |
| 73 | * CtkIconFactory supports a custom <sources> element, which can contain |
| 74 | * multiple <source> elements. The following attributes are allowed: |
| 75 | * |
| 76 | * - stock-id |
| 77 | * |
| 78 | * The stock id of the source, a string. This attribute is |
| 79 | * mandatory |
| 80 | * |
| 81 | * - filename |
| 82 | * |
| 83 | * The filename of the source, a string. This attribute is |
| 84 | * optional |
| 85 | * |
| 86 | * - icon-name |
| 87 | * |
| 88 | * The icon name for the source, a string. This attribute is |
| 89 | * optional. |
| 90 | * |
| 91 | * - size |
| 92 | * |
| 93 | * Size of the icon, a #CtkIconSize enum value. This attribute is |
| 94 | * optional. |
| 95 | * |
| 96 | * - direction |
| 97 | * |
| 98 | * Direction of the source, a #CtkTextDirection enum value. This |
| 99 | * attribute is optional. |
| 100 | * |
| 101 | * - state |
| 102 | * |
| 103 | * State of the source, a #CtkStateType enum value. This |
| 104 | * attribute is optional. |
| 105 | * |

| 254 | * Creates a new #CtkIconFactory. An icon factory manages a collection |
| 255 | * of #CtkIconSets; a #CtkIconSet manages a set of variants of a |
| 256 | * particular icon (i.e. a #CtkIconSet contains variants for different |
| 257 | * sizes and widget states). Icons in an icon factory are named by a |
| 258 | * stock ID, which is a simple string identifying the icon. Each |
| 259 | * #CtkStyle has a list of #CtkIconFactorys derived from the current |
| 260 | * theme; those icon factories are consulted first when searching for |
| 261 | * an icon. If the theme doesn’t set a particular icon, CTK+ looks for |
| 262 | * the icon in a list of default icon factories, maintained by |
| 263 | * ctk_icon_factory_add_default() and |
| 264 | * ctk_icon_factory_remove_default(). Applications with icons should |
| 265 | * add a default icon factory with their icons, which will allow |
| 266 | * themes to override the icons for the application. |
| 267 | * |
| 268 | * Returns: a new #CtkIconFactory |

| 1632 | * scaled, made to look insensitive, etc. in |

| 1635 | * a #CtkIconSource. |
| 1636 | * |
| 1637 | * This function copies @source, so you can reuse the same source immediately |
| 1638 | * without affecting the icon set. |
| 1639 | * |
| 1640 | * An example of when you’d use this function: a web browser’s "Back |
| 1641 | * to Previous Page" icon might point in a different direction in |
| 1642 | * Hebrew and in English; it might look different when insensitive; |
| 1643 | * and it might change size depending on toolbar mode (small/large |
| 1644 | * icons). So a single icon set would contain all those variants of |
| 1645 | * the icon, and you might add a separate source for each one. |
| 1646 | * |
| 1647 | * You should nearly always add a “default” icon source with all |
| 1648 | * fields wildcarded, which will be used as a fallback if no more |
| 1649 | * specific source matches. #CtkIconSet always prefers more specific |
| 1650 | * icon sources to more generic icon sources. The order in which you |

| 1755 | * ctk_icon_source_new: |
| 1756 | * |
| 1757 | * Creates a new #CtkIconSource. A #CtkIconSource contains a #GdkPixbuf (or |
| 1758 | * image filename) that serves as the base image for one or more of the |
| 1759 | * icons in a #CtkIconSet, along with a specification for which icons in the |
| 1760 | * icon set will be based on that pixbuf or image file. An icon set contains |
| 1761 | * a set of icons that represent “the same” logical concept in different states, |
| 1762 | * different global text directions, and different sizes. |
| 1763 | * |
| 1764 | * So for example a web browser’s “Back to Previous Page” icon might |
| 1765 | * point in a different direction in Hebrew and in English; it might |
| 1766 | * look different when insensitive; and it might change size depending |
| 1767 | * on toolbar mode (small/large icons). So a single icon set would |
| 1768 | * contain all those variants of the icon. #CtkIconSet contains a list |
| 1769 | * of #CtkIconSource from which it can derive specific icon variants in |
| 1770 | * the set. |
| 1771 | * |
| 1772 | * In the simplest case, #CtkIconSet contains one source pixbuf from |
| 1773 | * which it derives all variants. The convenience function |
| 1774 | * ctk_icon_set_new_from_pixbuf() handles this case; if you only have |
| 1775 | * one source pixbuf, just use that function. |
| 1776 | * |
| 1777 | * If you want to use a different base pixbuf for different icon |
| 1778 | * variants, you create multiple icon sources, mark which variants |
| 1779 | * they’ll be used to create, and add them to the icon set with |
| 1780 | * ctk_icon_set_add_source(). |
| 1781 | * |
| 1782 | * By default, the icon source has all parameters wildcarded. That is, |
| 1783 | * the icon source will be used as the base icon for any desired text |
| 1784 | * direction, widget state, or icon size. |
| 1785 | * |
| 1786 | * Returns: a new #CtkIconSource |
