/* Entry/Type to Search
|
|
*
|
|
* GtkSearchEntry provides an entry that is ready for search.
|
|
*
|
|
* Search entries have their "search-changed" signal delayed and
|
|
* should be used when the search operation is slow, such as big
|
|
* datasets to search, or online searches.
|
|
*
|
|
* GtkSearchBar allows have a hidden search entry that 'springs
|
|
* into action' upon keyboard input.
