subclass of <a class="link" href="GtkEntry.html" title="GtkEntry"><span class="type">GtkEntry</span></a> that has been tailored for use as a search entry.</p> <p>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.</p> <p>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.</p> <p>To make filtering appear more reactive, it is a good idea to not react to every change in the entry text immediately, but only after a short delay. To support this, <a class="link" href="GtkSearchEntry.html" title="GtkSearchEntry"><span class="type">GtkSearchEntry</span></a> emits the <a class="link" href="GtkSearchEntry.html#GtkSearchEntry-search-changed" title="The “search-changed” signal"><span class="type">“search-changed”</span></a> signal which can be used instead of the <a class="link" href="GtkEditable.html#GtkEditable-changed" title="The “changed” signal"><span class="type">“changed”</span></a> signal.</p> <p>The <a class="link" href="GtkSearchEntry.html#GtkSearchEntry-previous-match" title="The “previous-match” signal"><span class="type">“previous-match”</span></a>, <a class="link" href="GtkSearchEntry.html#GtkSearchEntry-next-match" title="The “next-match” signal"><span class="type">“next-match”</span></a> and <a class="link" href="GtkSearchEntry.html#GtkSearchEntry-stop-search" title="The “stop-search” signal"><span class="type">“stop-search”</span></a> signals can be used to implement moving between search results and ending the search.</p> <p>Often, GtkSearchEntry will be fed events by means of being placed inside a <a class="link" href="GtkSearchBar.html" title="GtkSearchBar"><span class="type">GtkSearchBar</span></a>.
