Struct gtk4::SearchEntry

#[repr(transparent)]
pub struct SearchEntry { /* private fields */ }

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 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, 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.

Signals

activate

Emitted when the entry is activated.

The keybindings for this signal are all forms of the Enter key.

Action

next-match

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.

Action

previous-match

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.

Action

search-changed

Emitted with a delay. The length of the delay can be changed with the search-delay property.

search-started

Emitted when the user initiated a search on the entry.

stop-search

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.

Action

Widget

destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

direction-changed

Emitted when the text direction of a widget changes.

hide

Emitted when @widget is hidden.

keynav-failed

Emitted if keyboard navigation fails.

See WidgetExt::keynav_failed() for details.

map

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of unmap.

mnemonic-activate

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling is false, or just makes @widget grab focus if @group_cycling is true.

move-focus

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.

Action

query-tooltip

Emitted when the widgets tooltip is about to be shown.

This happens when the has-tooltip property is true and the hover timeout has expired with the cursor hovering “above” @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. If this is the case true should be returned, false otherwise. Note that if @keyboard_mode is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore destined function calls.

realize

Emitted when @widget is associated with a gdk::Surface.

This means that WidgetExt::realize() has been called or the widget has been mapped (that is, it is going to be drawn).

show

Emitted when @widget is shown.

state-flags-changed

Emitted when the widget state changes.

See WidgetExt::state_flags().

unmap

Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

unrealize

Emitted when the gdk::Surface associated with @widget is destroyed.

This means that WidgetExt::unrealize() has been called or the widget has been unmapped (that is, it is going to be hidden).

Editable

changed

Emitted at the end of a single user-visible operation on the contents.

E.g., a paste operation that replaces the contents of the selection will cause only one signal emission (even though it is implemented by first deleting the selection, then inserting the new content, and may cause multiple ::notify::text signals to be emitted).

delete-text

Emitted when text is deleted from the widget by the user.

The default handler for this signal will normally be responsible for deleting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the range of deleted text, or prevent it from being deleted entirely.

The @start_pos and @end_pos parameters are interpreted as for EditableExt::delete_text().

insert-text

Emitted when text is inserted into the widget by the user.

The default handler for this signal will normally be responsible for inserting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the inserted text, or prevent it from being inserted entirely.

Implementations

impl SearchEntry

pub fn new() -> SearchEntry

Creates a SearchEntry.

Returns

a new SearchEntry

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.

pub fn key_capture_widget(&self) -> Option<Widget>

Gets the widget that @self is capturing key events from.

Returns

The key capture widget.

pub fn search_delay(&self) -> u32

Available on crate feature v4_8 only.

Get the delay to be used between the last keypress and the search-changed signal being emitted.

Returns

a delay in milliseconds.

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
