* SECTION:gtksearchentry
* @Short_description: An entry which shows a search icon
* @Title: GtkSearchEntry
*
* #GtkSearchEntry is a subclass of #GtkEntry that has
* been tailored for use as a search entry.
*
* It will show an inactive symbolic "find" icon when the
* search entry is empty, and a symbolic "clear" icon when
* there is text. Clicking on the "clear" icon will empty
* the search entry.
*
* Note that the search/clear icon is shown using a secondary
* icon, and thus does not work if you are using the secondary
* icon position for some other purpose.
*
* Since: 3.6
