Struct PlatformInputHandler 

pub struct PlatformInputHandler { /* private fields */ }

Implementations

impl PlatformInputHandler

pub fn new(cx: AsyncWindowContext, handler: Box<dyn InputHandler>) -> Self

pub fn focus_id(&self) -> Option<FocusId>

Identifies the input field registered through Window::handle_input.

This identity survives adapter replacement during repaint. Backends can use it to detect a field change without restarting the keyboard session.

pub fn selected_text_range( &mut self, ignore_disabled_input: bool, ) -> Option<UTF16Selection>

pub fn marked_text_range(&mut self) -> Option<Range<usize>>

pub fn text_for_range( &mut self, range_utf16: Range<usize>, adjusted: &mut Option<Range<usize>>, ) -> Option<String>

pub fn replace_text_in_range( &mut self, replacement_range: Option<Range<usize>>, text: &str, )

pub fn replace_and_mark_text_in_range( &mut self, range_utf16: Option<Range<usize>>, new_text: &str, new_selected_range: Option<Range<usize>>, )

pub fn unmark_text(&mut self)

pub fn paste(&mut self, item: ClipboardItem)

pub fn bounds_for_range( &mut self, range_utf16: Range<usize>, ) -> Option<Bounds<Pixels>>

pub fn selection_bounds_for_range( &mut self, range_utf16: Range<usize>, ) -> Vec<Bounds<Pixels>>

pub fn apple_press_and_hold_enabled(&mut self) -> bool

pub fn dispatch_input(&mut self, input: &str, window: &mut Window, cx: &mut App)

pub fn compute_ime_candidate_bounds( marked_range: Option<Range<usize>>, selection: &UTF16Selection, bounds_for_range: impl FnMut(Range<usize>) -> Option<Bounds<Pixels>>, ) -> Option<Bounds<Pixels>>

pub fn selected_bounds( &mut self, window: &mut Window, cx: &mut App, ) -> Option<Bounds<Pixels>>

pub fn ime_candidate_bounds(&mut self) -> Option<Bounds<Pixels>>

pub fn character_index_for_point( &mut self, point: Point<Pixels>, ) -> Option<usize>

pub fn set_selected_text_range(&mut self, range_utf16: Range<usize>)

See InputHandler::set_selected_text_range.

pub fn element_bounds(&mut self) -> Option<Bounds<Pixels>>

See InputHandler::element_bounds.

pub fn text_length_utf16(&mut self) -> Option<usize>

See InputHandler::text_length_utf16.

pub fn accepts_text_input(&mut self, window: &mut Window, cx: &mut App) -> bool

pub fn query_accepts_text_input(&mut self) -> bool

pub fn query_accepts_focused_text_input(&mut self) -> bool

Checks eligibility against the current focus, including before the next frame is drawn.

Unlike the legacy acceptance query, this fails closed when the window cannot be updated and requires registration through Window::handle_input.

pub fn query_prefers_ime_for_printable_keys(&mut self) -> bool

See InputHandler::prefers_ime_for_printable_keys.

This is not a pure delegation to the handler: while a multi-stroke binding is pending this returns false regardless of the handler’s preference, because the next printable key may complete a binding whose prefix already bypassed the IME.

pub fn text_input_configuration( &mut self, window: &mut Window, cx: &mut App, ) -> TextInputConfiguration

See InputHandler::text_input_configuration.

pub fn text_input_editable_range(&mut self) -> Option<Range<usize>>

See InputHandler::text_input_editable_range.
