impl CustomNode for ButtonComponent

fn draw_sized( &self, cmd_buf: &mut Vec<DrawCommand>, text_style: &TextStyle, text_flow_style: &TextFlowStyle, _style: &Style, size: ContentSize, )

Emit draw commands fitted to the resolved content-box size.

fn intrinsic_size(&self) -> ContentSize

Intrinsic (content-box) size in pixels.

fn on_pointer_event(&self, event: PointerEvent) -> bool

Dispatches a platform-neutral pointer event.

fn set_hovered(&self, hovered: bool)

Updates the hover state for this node.

fn is_hovered(&self) -> bool

fn needs_repaint(&self) -> bool

Whether this node changed its visual state since the last check.

fn role(&self) -> Option<&'static str>

Accessibility role for this node (e.g. "button", "textbox", "img").

fn label(&self) -> Option<String>

Accessibility label (accessible name).

fn is_disabled(&self) -> bool

Whether this node is disabled and must not receive input.

fn draw( &self, cmd_buf: &mut Vec<DrawCommand>, text_style: &TextStyle, text_flow_style: &TextFlowStyle, )

Emit draw commands using the intrinsic content-box size.

fn popup( &self, _text_style: &TextStyle, _text_flow_style: &TextFlowStyle, ) -> Option<Popup>

Returns the node’s open popup (top-layer overlay), if any.

fn preserves_intrinsic_aspect_ratio(&self) -> bool

Whether one resolved dimension should scale the other dimension using the node’s intrinsic aspect ratio.

fn accepts_text_input(&self) -> bool

Whether this node can receive keyboard and IME text input.

fn set_focused(&self, _focused: bool)

Updates keyboard focus for this node.

fn is_focused(&self) -> bool

Returns whether this node currently owns keyboard focus.

fn handle_text_input(&self, _event: InputTextEvent) -> bool

Applies a platform-neutral text editing event.

fn is_composing(&self) -> bool

Returns whether an IME preedit string is active.

fn on_popup_pointer_event(&self, _event: PointerEvent) -> bool

Dispatches a pointer event on the node’s open popup.

fn dismiss_popup(&self)

Closes this node’s popup, if open (dismiss on an outside click).

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

Screen rectangle of the active IME composition underline, in content-box coordinates (x, y, width, height). None when nothing is composing.

fn value(&self) -> Option<String>

Current value for editable/stateful nodes.

impl Debug for ButtonComponent

fn fmt(&self, f: &mut Formatter<'_>) -> Result
