|

*
|
|
|
|
|
* #GtkIconTheme provides a facility for looking up icons by name
|
|
|
|
|
* and size. The main reason for using a name rather than simply
|
|
|
|
|
* providing a filename is to allow different icons to be used
|
2014-02-04 23:10:11 +00:00
|
|
|
|
* depending on what “icon theme” is selected
|
2011-04-14 21:07:29 +00:00
|
|
|
|
* by the user. The operation of icon themes on Linux and Unix
|
2014-02-04 23:53:51 +00:00
|
|
|
|
* follows the [Icon Theme Specification](http://www.freedesktop.org/Standards/icon-theme-spec)
|
2014-06-22 20:46:11 +00:00
|
|
|
|
* There is a fallback icon theme, named `hicolor`, where applications
|
|
|
|
|
* should install their icons, but additional icon themes can be installed
|
|
|
|
|
* as operating system vendors and users choose.
|
2011-04-14 21:07:29 +00:00
|
|
|
|
*
|
|
|
|
|
* In many cases, named themes are used indirectly, via #GtkImage
|
2016-10-22 15:25:57 +00:00
|
|
|
|
* rather than directly, but looking up icons
|
2011-04-14 21:07:29 +00:00
|
|
|
|
* directly is also simple. The #GtkIconTheme object acts
|
|
|
|
|
* as a database of all the icons in the current theme. You
|
2014-02-07 18:01:26 +00:00
|
|
|
|
* can create new #GtkIconTheme objects, but it’s much more
|
2017-10-31 07:25:10 +00:00
|
|
|
|
* efficient to use the standard icon theme for the #GdkDisplay
|
2011-04-14 21:07:29 +00:00
|
|
|
|
* so that the icon information is shared with other people
|
2014-06-22 20:46:11 +00:00
|
|
|
|
* looking up icons.
