GI.Gtk.Objects.SearchBar

SearchBar is a container made to have a search entry (possibly with additional connex widgets, such as drop-down menus, or buttons) built-in. 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 searchBarSetKeyCaptureWidget. 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 searchBarConnectEntry. The following example shows you how to create a more complex search entry.

CSS nodes

plain code

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

GtkSearchBar 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.

class (GObject o, IsDescendantOf SearchBar o) => IsSearchBar o

Type class for types which can be safely cast to SearchBar, for instance with toSearchBar.

Instances

Defined in GI.Gtk.Objects.SearchBar

toSearchBar :: (MonadIO m, IsSearchBar o) => o -> m SearchBar

Cast to SearchBar, for types for which this is known to be safe. For general casts, use castTo.

noSearchBar :: Maybe SearchBar

Methods

Overloaded methods

connectEntry

searchBarConnectEntry

Arguments

:: (HasCallStack, MonadIO m, IsSearchBar a, IsEditable b)

=> a

bar: a SearchBar

-> b

entry: a Editable

-> m ()

Connects the Entry widget passed as the one to be used in this search bar. The entry should be a descendant of the search bar. This is only required if the entry isn’t the direct child of the search bar (as in our main example).

getKeyCaptureWidget

searchBarGetKeyCaptureWidget

Arguments

:: (HasCallStack, MonadIO m, IsSearchBar a)

=> a

bar: a SearchBar

-> m Widget

Returns: The key capture widget.

Gets the widget that bar is capturing key events from.

getSearchMode

searchBarGetSearchMode

Arguments

:: (HasCallStack, MonadIO m, IsSearchBar a)

=> a

bar: a SearchBar

-> m Bool

Returns: whether search mode is toggled on

Returns whether the search mode is on or off.

getShowCloseButton

searchBarGetShowCloseButton

Arguments

:: (HasCallStack, MonadIO m, IsSearchBar a)

=> a

bar: a SearchBar

-> m Bool

Returns: whether the close button is shown

Returns whether the close button is shown.

new

searchBarNew

Arguments

:: (HasCallStack, MonadIO m)

=> m SearchBar

Returns: a new SearchBar

Creates a SearchBar. You will need to tell it about which widget is going to be your text entry using searchBarConnectEntry.

setKeyCaptureWidget

searchBarSetKeyCaptureWidget

Arguments

:: (HasCallStack, MonadIO m, IsSearchBar a, IsWidget b)

=> a

bar: a SearchBar

-> Maybe b

widget: a Widget

-> m ()

Sets widget as the widget that bar 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.

setSearchMode

searchBarSetSearchMode

Arguments

:: (HasCallStack, MonadIO m, IsSearchBar a)

=> a

bar: a SearchBar

-> Bool

searchMode: the new state of the search mode

-> m ()

Switches the search mode on or off.

setShowCloseButton

searchBarSetShowCloseButton

Arguments

:: (HasCallStack, MonadIO m, IsSearchBar a)

=> a

bar: a SearchBar

-> Bool

visible: whether the close button will be shown or not

-> m ()

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.

Properties

searchModeEnabled

Whether the search mode is on and the search bar shown.

See searchBarSetSearchMode for details.

constructSearchBarSearchModeEnabled :: IsSearchBar o => Bool -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “search-mode-enabled” property. This is rarely needed directly, but it is used by new.

getSearchBarSearchModeEnabled :: (MonadIO m, IsSearchBar o) => o -> m Bool

Get the value of the “search-mode-enabled” property. When overloading is enabled, this is equivalent to

get searchBar #searchModeEnabled

setSearchBarSearchModeEnabled :: (MonadIO m, IsSearchBar o) => o -> Bool -> m ()

Set the value of the “search-mode-enabled” property. When overloading is enabled, this is equivalent to

set searchBar [ #searchModeEnabled := value ]

showCloseButton

Whether to show the close button in the search bar.

constructSearchBarShowCloseButton :: IsSearchBar o => Bool -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “show-close-button” property. This is rarely needed directly, but it is used by new.

getSearchBarShowCloseButton :: (MonadIO m, IsSearchBar o) => o -> m Bool

Get the value of the “show-close-button” property. When overloading is enabled, this is equivalent to

get searchBar #showCloseButton

setSearchBarShowCloseButton :: (MonadIO m, IsSearchBar o) => o -> Bool -> m ()

Set the value of the “show-close-button” property. When overloading is enabled, this is equivalent to

set searchBar [ #showCloseButton := value ]
