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.
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, GtkSearchEntry emits the “search-changed” signal which can be used instead of the “changed” signal.
The “previous-match”, “next-match” and “stop-search” signals can be used to implement moving between search results and ending the search.
Often, GtkSearchEntry will be fed events by means of being
placed inside a GtkSearchBar. If that is not the case,
you can use gtk_search_entry_set_key_capture_widget()
to let it
capture key input from another widget.
GtkWidget *
gtk_search_entry_new (void
);
Creates a GtkSearchEntry, with a find icon when the search field is empty, and a clear icon when it isn't.
void gtk_search_entry_set_key_capture_widget (GtkSearchEntry *entry
,GtkWidget *widget
);
Sets widget
as the widget that entry
will capture key events from.
Key events are consumed by the search entry to start or continue a search.
If the entry is part of a GtkSearchBar, it is preferable
to call gtk_search_bar_set_key_capture_widget()
instead, which
will reveal the entry in addition to triggering the search entry.
GtkWidget *
gtk_search_entry_get_key_capture_widget
(GtkSearchEntry *entry
);
Gets the widget that entry
is capturing key events from.
“activates-default”
property“activates-default” gboolean
Whether to activate the default widget (such as the default button in a dialog) when Enter is pressed.
Flags: Read / Write
Default value: FALSE
“placeholder-text”
property“placeholder-text” gchar *
Show text in the entry when it’s empty and unfocused.
Flags: Read / Write
Default value: NULL
“activate”
signalvoid user_function (GtkSearchEntry *searchentry, gpointer user_data)
Flags: Action
“next-match”
signalvoid user_function (GtkSearchEntry *entry, gpointer user_data)
The ::next-match signal is a keybinding signal which gets emitted when the user initiates a move to the next match for the current search string.
Applications should connect to it, to implement moving between matches.
The default bindings for this signal is Ctrl-g.

“previous-match”
signalvoid user_function (GtkSearchEntry *entry, gpointer user_data)
The ::previous-match signal is a keybinding signal which gets emitted when the user initiates a move to the previous match for the current search string.
Applications should connect to it, to implement moving between matches.
The default bindings for this signal is Ctrl-Shift-g.

Flags: Action
“search-changed”
signalvoid user_function (GtkSearchEntry *entry, gpointer user_data)
The “search-changed” signal is emitted with a short delay of 150 milliseconds after the last change to the entry text.

the entry on which the signal was emitted |
|
user_data |
user data set when the signal handler was connected. |
Flags: Run Last
“search-started”
signalvoid user_function (GtkSearchEntry *entry, gpointer user_data)
The ::search-started signal gets emitted when the user initiated a search on the entry.

the entry on which the signal was emitted |
|
user_data |
user data set when the signal handler was connected. |
Flags: Run Last
“stop-search”
signalvoid user_function (GtkSearchEntry *entry, gpointer user_data)
The ::stop-search signal is a keybinding signal which gets emitted when the user stops a search via keyboard input.
Applications should connect to it, to implement hiding the search entry in this case.
The default bindings for this signal is Escape.
