Extensions for composing reusable wrapper behavior around component subtrees.

Required Methods

fn window_insets_padding(self, insets: WindowInsets) -> Modifier

Pads and consumes the space not already occupied by enclosing inset modifiers.

fn consume_window_insets(self, insets: WindowInsets) -> Modifier

Marks inset space as occupied for nested padding and size modifiers.

fn window_insets_left_width(self, insets: WindowInsets) -> Modifier

Sets width to the remaining left window inset.

fn window_insets_top_height(self, insets: WindowInsets) -> Modifier

Sets height to the remaining top window inset.

fn window_insets_right_width(self, insets: WindowInsets) -> Modifier

Sets width to the remaining right window inset.

fn window_insets_bottom_height(self, insets: WindowInsets) -> Modifier

Sets height to the remaining bottom window inset.

fn padding(self, padding: Padding) -> Modifier

Adds padding around the content.

fn padding_all(self, padding: Dp) -> Modifier

Adds symmetric padding on all edges.

fn padding_symmetric(self, horizontal: Dp, vertical: Dp) -> Modifier

Adds symmetric padding for horizontal and vertical edges.

fn offset(self, x: Dp, y: Dp) -> Modifier

Offsets the content without affecting layout size.

fn alpha(self, alpha: f32) -> Modifier

Multiplies the opacity of the subtree by alpha.

fn clip_to_bounds(self) -> Modifier

Clips descendants to this modifier’s bounds.

fn clip_shape(self, shape: Shape) -> Modifier

Clips this node and its descendants to a shape without resizing content.

fn vertical_scroll(self, controller: State<ScrollableController>) -> Modifier

Makes this node a vertical scroll viewport driven by controller.

fn horizontal_scroll(self, controller: State<ScrollableController>) -> Modifier

Makes this node a horizontal scroll viewport driven by controller.

fn scroll( self, controller: State<ScrollableController>, vertical: bool, horizontal: bool, ) -> Modifier

Makes this node a scroll viewport on the selected axes.

fn background(self, color: Color) -> Modifier

Draws a background behind the subtree.

fn background_with_shape(self, color: Color, shape: Shape) -> Modifier

Draws a background behind the subtree using a custom shape.

fn background_with_scaled_shape( self, color: Color, shape: Shape, scale: [f32; 2], ) -> Modifier

Draws a background scaled around its center while preserving layout and input bounds.

Both scale axes must be finite and in 0..=1. A zero axis draws nothing.

fn border(self, width: Dp, color: Color) -> Modifier

Draws a border stroke above the subtree.

fn border_with_shape(self, width: Dp, color: Color, shape: Shape) -> Modifier

Draws a border stroke above the subtree using a custom shape.

fn shadow(self, scheme: &MaterialColorScheme, args: &ShadowArgs) -> Modifier

Adds a shadow with advanced configuration options.

fn size(self, width: Dp, height: Dp) -> Modifier

Constrains the content to an exact size when possible.

fn required_size(self, width: Dp, height: Dp) -> Modifier

Pins the content to an exact size regardless of incoming constraints.

fn required_width(self, width: Dp) -> Modifier

Pins the content width regardless of incoming constraints.

fn required_height(self, height: Dp) -> Modifier

Pins the content height regardless of incoming constraints.

fn default_min_size(self, min_width: Dp, min_height: Dp) -> Modifier

Applies a default minimum size only when the incoming axis leaves the minimum open, so an explicit outer size always wins.

fn width(self, width: Dp) -> Modifier

Constrains the content to an exact width when possible.

fn height(self, height: Dp) -> Modifier

Constrains the content to an exact height when possible.

fn size_in( self, min_width: Option<Dp>, max_width: Option<Dp>, min_height: Option<Dp>, max_height: Option<Dp>, ) -> Modifier

Constrains the content size within optional min/max bounds.

fn constrain( self, width: Option<AxisConstraint>, height: Option<AxisConstraint>, ) -> Modifier

Applies explicit width/height interval constraints.

fn fill_max_width(self) -> Modifier

Fills the available width within parent bounds.

fn fill_max_height(self) -> Modifier

Fills the available height within parent bounds.

fn fill_max_size(self) -> Modifier

Fills the available size within parent bounds.

fn minimum_interactive_component_size(self) -> Modifier

Enforces a minimum interactive size by expanding and centering content.

fn weight(self, weight: f32) -> Modifier

Provides weighted parent data for row and column layouts.

fn align(self, alignment: Alignment) -> Modifier

Provides alignment parent data for layered boxed layouts.

fn draggable<C>(self, on_drag_delta: C) -> Modifier

where C: Into<CallbackWith<DragDelta, ()>>,

Emits drag deltas for free-form dragging.

fn draggable_with(self, args: DraggableArgs) -> Modifier

Emits drag deltas with custom drag configuration.

fn block_touch_propagation(self) -> Modifier

Prevents cursor events from propagating to components behind this subtree.

fn semantics(self, args: SemanticsArgs) -> Modifier

Attaches accessibility semantics metadata to this subtree.

fn clear_and_set_semantics(self, args: SemanticsArgs) -> Modifier

Clears descendant semantics and applies the provided metadata.

fn clickable<C>(self, on_click: C) -> Modifier

where C: Into<Callback>,

Makes the subtree clickable with optional ripple feedback and an accessibility click action.

fn clickable_with(self, args: ClickableArgs) -> Modifier

Makes the subtree clickable with advanced configuration options.

fn toggleable<C>(self, value: bool, on_value_change: C) -> Modifier

where C: Into<CallbackWith<bool, ()>>,

Makes the subtree toggleable with optional ripple/state-layer feedback.

fn toggleable_with(self, args: ToggleableArgs) -> Modifier

Makes the subtree toggleable with advanced configuration options.

fn selectable<C>(self, selected: bool, on_click: C) -> Modifier

where C: Into<Callback>,

Makes the subtree selectable with optional ripple/state-layer feedback.

fn selectable_with(self, args: SelectableArgs) -> Modifier

Makes the subtree selectable with advanced configuration options.

fn window_drag_region(self) -> Modifier

Marks this subtree as a draggable window region. On macOS, double-clicking the region follows the system title bar preference.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
