| 69 | * @Short_description: Looking up icons by name |
| 70 | * @Title: CtkIconTheme |
| 71 | * |
| 72 | * #CtkIconTheme provides a facility for looking up icons by name |
| 73 | * and size. The main reason for using a name rather than simply |
| 74 | * providing a filename is to allow different icons to be used |
| 75 | * depending on what “icon theme” is selected |
| 76 | * by the user. The operation of icon themes on Linux and Unix |
| 77 | * follows the [Icon Theme Specification](http://www.freedesktop.org/Standards/icon-theme-spec) |
| 78 | * There is a fallback icon theme, named `hicolor`, where applications |
| 79 | * should install their icons, but additional icon themes can be installed |
| 80 | * as operating system vendors and users choose. |
| 81 | * |
| 82 | * Named icons are similar to the deprecated [Stock Items][ctkstock], |
| 83 | * and the distinction between the two may be a bit confusing. |
| 84 | * A few things to keep in mind: |
| 85 | * |
| 86 | * - Stock images usually are used in conjunction with |
| 87 | * [Stock Items][ctkstock], such as %CTK_STOCK_OK or |
| 88 | * %CTK_STOCK_OPEN. Named icons are easier to set up and therefore |
| 89 | * are more useful for new icons that an application wants to |
| 90 | * add, such as application icons or window icons. |
| 91 | * |
| 92 | * - Stock images can only be loaded at the symbolic sizes defined |
| 93 | * by the #CtkIconSize enumeration, or by custom sizes defined |
| 94 | * by ctk_icon_size_register(), while named icons are more flexible |
| 95 | * and any pixel size can be specified. |
| 96 | * |
| 97 | * - Because stock images are closely tied to stock items, and thus |
| 98 | * to actions in the user interface, stock images may come in |
| 99 | * multiple variants for different widget states or writing |
| 100 | * directions. |
| 101 | * |
| 102 | * A good rule of thumb is that if there is a stock image for what |
| 103 | * you want to use, use it, otherwise use a named icon. It turns |
| 104 | * out that internally stock images are generally defined in |
| 105 | * terms of one or more named icons. (An example of the |
| 106 | * more than one case is icons that depend on writing direction; |
| 107 | * %CTK_STOCK_GO_FORWARD uses the two themed icons |
| 108 | * “ctk-stock-go-forward-ltr” and “ctk-stock-go-forward-rtl”.) |
| 109 | * |
| 110 | * In many cases, named themes are used indirectly, via #CtkImage |
| 111 | * or stock items, rather than directly, but looking up icons |
| 112 | * directly is also simple. The #CtkIconTheme object acts |
| 113 | * as a database of all the icons in the current theme. You |
| 114 | * can create new #CtkIconTheme objects, but it’s much more |
| 115 | * efficient to use the standard icon theme for the #CdkScreen |
| 116 | * so that the icon information is shared with other people |
| 117 | * looking up icons. |

| 125 | * "my-icon-name", // icon name |
