Struct gtk4::SearchBar[][src]

pub struct SearchBar(_);
Expand description

SearchBar is a container made to have a search entry.

An example GtkSearchBar

It can also contain additional widgets, such as drop-down menus, or buttons. The search bar would appear when a search is started through typing on the keyboard, or the application’s search mode is toggled on.

For keyboard presses to start a search, the search bar must be told of a widget to capture key events from through set_key_capture_widget(). This widget will typically be the top-level window, or a parent container of the search bar. Common shortcuts such as Ctrl+F should be handled as an application action, or through the menu items.

You will also need to tell the search bar about which entry you are using as your search entry using connect_entry().

The following example shows you how to create a more complex search entry.

A simple example

CSS nodes

searchbar
╰── revealer
    ╰── box
         ├── [child]
         ╰── [button.close]

SearchBar has a main CSS node with name searchbar. It has a child node with name revealer that contains a node with name box. The box node contains both the CSS node of the child widget as well as an optional button node which gets the .close style class applied.

Accessibility

SearchBar uses the AccessibleRole::Search role.

Implementations

Creates a SearchBar.

You will need to tell it about which widget is going to be your text entry using connect_entry().

Returns

a new SearchBar

Creates a new builder-pattern struct instance to construct SearchBar objects.

This method returns an instance of SearchBarBuilder which can be used to create SearchBar objects.

pub fn connect_entry(&self, entry: &impl IsA<Editable>)

Connects the `GtkEditable widget passed as the one to be used in this search bar.

The entry should be a descendant of the search bar. Calling this function manually is only required if the entry isn’t the direct child of the search bar (as in our main example).

entry

a Editable

Gets the child widget of self.

Returns

the child widget of self

Gets the widget that self is capturing key events from.

Returns

The key capture widget.

Returns whether the search mode is on or off.

Returns

whether search mode is toggled on

Returns whether the close button is shown.

Returns

whether the close button is shown

Sets the child widget of self.

child

the child widget

Sets widget as the widget that self will capture key events from.

If key events are handled by the search bar, the bar will be shown, and the entry populated with the entered text.

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

Switches the search mode on or off.

search_mode

the new state of the search mode

Shows or hides the close button.

Applications that already have a “search” toggle button should not show a close button in their search bar, as it duplicates the role of the toggle button.

visible

whether the close button will be shown or not
