Struct gtk4::SearchBar [−][src]
pub struct SearchBar(_);Expand description
SearchBar is a container made to have a search entry.
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().
Creating a search bar
The following example shows you how to create a more complex search entry.
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.
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
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

Tries to cast to an object of type T. This handles upcasting, downcasting

runtime, while downcast and upcast will do many checks at compile-time already. Read more
