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.

An example GtkSearchEntry

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§

Creates a SearchEntry.

Returns

a new SearchEntry

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.

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

Returns

The key capture widget.

Available on crate feature 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.

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

Available on crate feature 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

Whether to activate the default widget when Enter is pressed.

Whether to activate the default widget when Enter is pressed.

The text that will be displayed in the SearchEntry when it is empty and unfocused.

The text that will be displayed in the SearchEntry when it is empty and unfocused.

Emitted when the entry is activated.

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

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.

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.

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

Emitted when the user initiated a search on the entry.

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.

Available on crate feature v4_8 only.
