impl Widget for TextBox

fn as_any(&self) -> &dyn Any

fn as_any_mut(&mut self) -> &mut dyn Any

fn get_key(&self) -> Option<&SmolStr>

fn is_dirty(&self) -> bool

fn set_dirty(&mut self, dirty: bool)

fn style(&self) -> &Style

fn style_mut(&mut self) -> &mut Style

fn computed_style(&self) -> &Style

fn interaction(&self) -> Option<&Interaction>

fn interaction_mut(&mut self) -> Option<&mut Interaction>

fn layout(&mut self, rect: LayoutBox)

fn layout_box(&self) -> &LayoutBox

fn debug_name(&self) -> &'static str

fn measure( &self, ctx: &mut MeasureContext<'_>, constraints: Constraints, ) -> MeasureResult

fn paint(&self, ctx: &mut PaintContext<'_>)

fn event(&mut self, event: &InputEvent, ctx: &mut EventCtx) -> EventStatus

fn content_eq(&self, other: &dyn Widget) -> bool

fn cascade_style(&mut self, parent: &Style, anim: &mut AnimationManager)

fn after_interaction_transfer(&mut self)

fn transfer_interaction_state(&mut self, old: &dyn Widget)

fn transfer_measured_state(&mut self, old: &dyn Widget)

fn cancel_text_selection(&mut self)

fn blink_interval(&self) -> Option<Duration>

fn anim_id(&self) -> WidgetId

Stable per-instance animation key namespace. Assign once in the constructor via WidgetId::new_unique() and preserve it across reconciliation so in-flight transitions aren’t reset.

fn native_text_input(&self) -> Option<NativeTextInputSnapshot>

Some(...) marks this widget as backed by a real DOM <input> on web targets. None (the default) means it has no native counterpart.

fn set_native_text_value(&mut self, value: &str, ctx: &mut EventCtx)

Applies a value typed into the native DOM <input> back onto this widget’s own state.

fn on_mount(&mut self)

Called once, right after this widget is inserted into the tree.

fn on_unmount(&mut self)

Called once, right before this widget is permanently removed from the tree.

fn children(&self) -> &[Box<dyn Widget>]

fn children_mut(&mut self) -> Option<&mut Vec<Box<dyn Widget>>>

fn scroll_offset(&self) -> (f32, f32)

Additional scroll translation applied to this widget’s children during layout, in logical pixels.

fn set_content_size(&mut self, _size: (f32, f32))

Reports this widget’s total content size after layout, which may exceed layout_box() when children overflow it.

fn clip_children(&self) -> Option<(f32, f32, f32, f32)>

The rectangle this widget clips its children’s painted output to, in absolute screen coordinates. None means no clipping.

fn on_layout_pass(&self, _ctx: &mut MeasureContext<'_>)

Runs once per full layout pass for every widget, leaf or not, purely so a widget can cache intrinsic measurements it needs later for painting (e.g. a popup’s natural width) without affecting its own flex/grid size, which measure alone controls.

fn paint_overlay(&self, _ctx: &mut PaintContext<'_>)

Painted after every descendant, on top of them, and never cached - used for overlays like a scrollbar thumb that depend on live state.

fn paint_box(&self, ctx: &mut PaintContext<'_>)

fn paint_edge_borders( &self, ctx: &mut PaintContext<'_>, layout: LayoutBox, b: &Border, sf: f32, )

fn paint_shadow_layer( &self, ctx: &mut PaintContext<'_>, layout: LayoutBox, radius: f32, shadow: &BoxShadow, sf: f32, )

fn paint_outline(&self, ctx: &mut PaintContext<'_>)

fn paint_focus(&self, ctx: &mut PaintContext<'_>)

fn paint_top(&self, _ctx: &mut PaintContext<'_>)

Painted after every other widget’s own content and after all deferred text has been flushed - use this instead of paint_overlay for a popup that must render above everything else, including other widgets’ text (which is otherwise batched and flushed in its own pass after every widget’s rects).

fn hit_test(&self, point: (f32, f32)) -> bool

fn blocks_children_hit_test(&self, _point: (f32, f32)) -> bool

When true at point, hit-testing stops at this widget instead of descending into its children.

fn wants_animation_frame(&self) -> bool

Whether this widget needs a continuous per-frame animation callback (InputEvent::AnimationTick) right now, independent of focus.

fn selectable_text(&self) -> Option<&str>

HTML-style selectable text content for mouse selection / Ctrl+C. None opts the widget out entirely (e.g. Button, TextBox).

fn text_selection(&self) -> Option<(usize, usize)>

fn set_text_selection(&mut self, _range: Option<(usize, usize)>)

fn text_index_at(&self, _point: (f32, f32)) -> usize

Nearest character index to an absolute screen point, used by cross-widget drag selection to know where a widget’s own selection should start or end.

fn select_all_text(&mut self)

impl WidgetContent for TextBox

fn with_content(self, content: impl Into<SmolStr>) -> Self
