GI.Gtk.Objects.SearchBar

Description

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, events will need to be forwarded from the top-level window that contains the search bar. See searchBarHandleEvent for example code. 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

GtkSearchBar has a single CSS node with name searchbar.

connectEntry

searchBarConnectEntry Source #

Arguments

:: (HasCallStack, MonadIO m, IsSearchBar a, IsEntry b) 
=> a

bar: a SearchBar

-> b

entry: a Entry

-> 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).

Since: 3.10

getSearchMode

searchBarGetSearchMode Source #

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.

Since: 3.10

getShowCloseButton

searchBarGetShowCloseButton Source #

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.

Since: 3.10

handleEvent

searchBarHandleEvent Source #

Arguments

:: (HasCallStack, MonadIO m, IsSearchBar a) 
=> a

bar: a SearchBar

-> Event

event: a Event containing key press events

-> m Bool

Returns: EVENT_STOP if the key press event resulted in text being entered in the search entry (and revealing the search bar if necessary), EVENT_PROPAGATE otherwise.

This function should be called when the top-level window which contains the search bar received a key event.

If the key event is handled by the search bar, the bar will be shown, the entry populated with the entered text and EVENT_STOP will be returned. The caller should ensure that events are not propagated further.

If no entry has been connected to the search bar, using searchBarConnectEntry, this function will return immediately with a warning.

Showing the search bar on key presses

C code

static gboolean
on_key_press_event (GtkWidget *widget,
                    GdkEvent  *event,
                    gpointer   user_data)
{
  GtkSearchBar *bar = GTK_SEARCH_BAR (user_data);
  return gtk_search_bar_handle_event (bar, event);
}

static void
create_toplevel (void)
{
  GtkWidget *window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  GtkWindow *search_bar = gtk_search_bar_new ();

 // Add more widgets to the window...

  g_signal_connect (window,
                   "key-press-event",
                    G_CALLBACK (on_key_press_event),
                    search_bar);
}

Since: 3.10

new

searchBarNew Source #

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.

Since: 3.10

setSearchMode

searchBarSetSearchMode Source #

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.

Since: 3.10

setShowCloseButton

searchBarSetShowCloseButton Source #

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.

Since: 3.10

Properties

searchModeEnabled

No description available in the introspection data.

constructSearchBarSearchModeEnabled :: (IsSearchBar o, MonadIO m) => Bool -> m (GValueConstruct o) Source #

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 Source #

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 () Source #

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

set searchBar [ #searchModeEnabled := value ]

showCloseButton

No description available in the introspection data.

constructSearchBarShowCloseButton :: (IsSearchBar o, MonadIO m) => Bool -> m (GValueConstruct o) Source #

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 Source #

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 () Source #

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

set searchBar [ #showCloseButton := value ]
