|

|
|
* @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.
