Struct gtk4::SearchEntry
source · #[repr(transparent)]pub struct SearchEntry { /* private fields */ }Expand description
SearchEntry is an entry widget that has been tailored for use
as a search entry.
The main API for interacting with a SearchEntry as entry
is the Editable interface.
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.
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, SearchEntry
emits the signal::SearchEntry::search-changed signal which
can be used instead of the signal::Editable::changed signal.
The signal::SearchEntry::previous-match,
signal::SearchEntry::next-match and
signal::SearchEntry::stop-search signals can be used to
implement moving between search results and ending the search.
Often, SearchEntry will be fed events by means of being
placed inside a SearchBar. If that is not the case,
you can use set_key_capture_widget() to
let it capture key input from another widget.
SearchEntry provides only minimal API and should be used with
the Editable API.
CSS Nodes
entry.search
╰── text
SearchEntry has a single CSS node with name entry that carries
a .search style class, and the text node is a child of that.
Accessibility
SearchEntry uses the AccessibleRole::SearchBox role.

Implementations§
source§impl SearchEntry
impl SearchEntry
sourcepub fn new() -> SearchEntry
pub fn new() -> SearchEntry
sourcepub fn builder() -> SearchEntryBuilder
pub fn builder() -> SearchEntryBuilder
Creates a new builder-pattern struct instance to construct SearchEntry objects.
This method returns an instance of SearchEntryBuilder which can be used to create SearchEntry objects.
sourcepub fn key_capture_widget(&self) -> Option<Widget>
pub fn key_capture_widget(&self) -> Option<Widget>
sourcepub fn search_delay(&self) -> u32
Available on crate feature v4_8 only.
pub fn search_delay(&self) -> u32
v4_8 only.Get the delay to be used between the last keypress and the
signal::SearchEntry::search-changed signal being emitted.
Returns
a delay in milliseconds.
sourcepub fn set_key_capture_widget(&self, widget: Option<&impl IsA<Widget>>)
pub fn set_key_capture_widget(&self, widget: Option<&impl IsA<Widget>>)
Sets @widget as the widget that @self 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 SearchBar, it is preferable
to call SearchBar::set_key_capture_widget() instead,
which will reveal the entry in addition to triggering the
search entry.
Note that despite the name of this function, the events
are only ‘captured’ in the bubble phase, which means that
editable child widgets of @widget will receive text input
before it gets captured. If that is not desired, you can
capture and forward the events yourself with
EventControllerKey::forward().
widget
a Widget
sourcepub fn set_search_delay(&self, delay: u32)
Available on crate feature v4_8 only.
pub fn set_search_delay(&self, delay: u32)
v4_8 only.Set the delay to be used between the last keypress and the
signal::SearchEntry::search-changed signal being emitted.
delay
a delay in milliseconds
sourcepub fn activates_default(&self) -> bool
pub fn activates_default(&self) -> bool
Whether to activate the default widget when Enter is pressed.
sourcepub fn set_activates_default(&self, activates_default: bool)
pub fn set_activates_default(&self, activates_default: bool)
Whether to activate the default widget when Enter is pressed.
sourcepub fn placeholder_text(&self) -> Option<GString>
pub fn placeholder_text(&self) -> Option<GString>
The text that will be displayed in the SearchEntry
when it is empty and unfocused.
sourcepub fn set_placeholder_text(&self, placeholder_text: Option<&str>)
pub fn set_placeholder_text(&self, placeholder_text: Option<&str>)
The text that will be displayed in the SearchEntry
when it is empty and unfocused.
sourcepub fn connect_activate<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
pub fn connect_activate<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
Emitted when the entry is activated.
The keybindings for this signal are all forms of the Enter key.
pub fn emit_activate(&self)
sourcepub fn connect_next_match<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
pub fn connect_next_match<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
Emitted when the user initiates a move to the next match for the current search string.
This is a keybinding signal.
Applications should connect to it, to implement moving between matches.
The default bindings for this signal is Ctrl-g.
pub fn emit_next_match(&self)
sourcepub fn connect_previous_match<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_previous_match<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted when the user initiates a move to the previous match for the current search string.
This is a keybinding signal.
Applications should connect to it, to implement moving between matches.
The default bindings for this signal is Ctrl-Shift-g.
pub fn emit_previous_match(&self)
sourcepub fn connect_search_changed<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_search_changed<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted with a delay. The length of the delay can be
changed with the property::SearchEntry::search-delay
property.
sourcepub fn connect_search_started<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_search_started<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted when the user initiated a search on the entry.
sourcepub fn connect_stop_search<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_stop_search<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted when the user stops a search via keyboard input.
This is a keybinding signal.
Applications should connect to it, to implement hiding the search entry in this case.
The default bindings for this signal is Escape.
pub fn emit_stop_search(&self)
pub fn connect_activates_default_notify<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
pub fn connect_placeholder_text_notify<F: Fn(&Self) + 'static>(
&self,
f: F

&self,
f: F
) -> SignalHandlerId
