ParentDataModifier

Kotlin |Java

interface ParentDataModifier : Modifier.Element

androidx.compose.ui.layout.ParentDataModifier

A Modifier that provides data to the parent Layout. This can be read from within the the Layout during measurement and positioning, via IntrinsicMeasurable.parentData. Th parent data is commonly used to inform the parent how the child Layout should be measured and positioned.

Summary

Public methods
abstract Any?	Density.modifyParentData(parentData: Any?) Provides a parentData, given the parentData already provided through the modifier's chain.

Inherited functions
From class Element Boolean all(predicate: (Modifier.Element) -> Boolean) Returns true if predicate returns true for all Elements in this Modifier or if this Modifier contains no Elements. Boolean any(predicate: (Modifier.Element) -> Boolean) Returns true if predicate returns true for any Element in this Modifier. R foldIn(initial: R, operation: (R, Modifier.Element) -> R) Accumulates a value starting with initial and applying operation to the current value and each element from outside in. Elements wrap one another in a chain from left to right; an Element that appears to the left of another in a + expression or in operation's parameter order affects all of the elements that appear after it. foldIn may be used to accumulate a value starting from the parent or head of the modifier chain to the final wrapped child. R foldOut(initial: R, operation: (Modifier.Element, R) -> R) Accumulates a value starting with initial and applying operation to the current value and each element from inside out. Elements wrap one another in a chain from left to right; an Element that appears to the left of another in a + expression or in operation's parameter order affects all of the elements that appear after it. foldOut may be used to accumulate a value starting from the child or tail of the modifier chain up to the parent or head of the chain.
From class Modifier Modifier then(other: Modifier) Concatenates this modifier with another. Returns a Modifier representing this modifier followed by other in sequence.

Inherited extension functions

From androidx.compose.foundation.layout Modifier Modifier.absoluteOffset(x: Dp = 0.dp, y: Dp = 0.dp) Offset the content by (x dp, y dp). Modifier Modifier.absoluteOffset(offset: Density.() -> IntOffset) Offset the content by offset px. Modifier Modifier.absoluteOffsetPx(x: State<Float> = mutableStateOf(0f), y: State<Float> = mutableStateOf(0f)) Modifier Modifier.absolutePadding(left: Dp = 0.dp, top: Dp = 0.dp, right: Dp = 0.dp, bottom: Dp = 0.dp) Apply additional space along each edge of the content in Dp: left, top, right and bottom. Modifier Modifier.aspectRatio(@FloatRange(0.0, 3.4E38, false) ratio: Float, matchHeightConstraintsFirst: Boolean = false) Attempts to size the content to match a specified aspect ratio by trying to match one of the incoming constraints in the following order: Constraints.maxWidth, Constraints.maxHeight, Constraints.minWidth, Constraints.minHeight if matchHeightConstraintsFirst is false (which is the default), or Constraints.maxHeight, Constraints.maxWidth, Constraints.minHeight, Constraints.minWidth if matchHeightConstraintsFirst is true. Modifier Modifier.defaultMinSizeConstraints(minWidth: Dp = Dp.Unspecified, minHeight: Dp = Dp.Unspecified) Constrain the size of the wrapped layout only when it would be otherwise unconstrained: the minWidth and minHeight constraints are only applied when the incoming corresponding constraint is 0. Modifier Modifier.fillMaxHeight(@FloatRange(0.0, 1.0) fraction: Float = 1f) Have the content fill (possibly only partially) the Constraints.maxHeight of the incoming measurement constraints, by setting the minimum height and the maximum height to be equal to the maximum height multiplied by fraction. Modifier Modifier.fillMaxSize(@FloatRange(0.0, 1.0) fraction: Float = 1f) Have the content fill (possibly only partially) the Constraints.maxWidth and Constraints.maxHeight of the incoming measurement constraints, by setting the minimum width and the maximum width to be equal to the maximum width multiplied by fraction, as well as the minimum height and the maximum height to be equal to the maximum height multiplied by fraction. Modifier Modifier.fillMaxWidth(@FloatRange(0.0, 1.0) fraction: Float = 1f) Have the content fill (possibly only partially) the Constraints.maxWidth of the incoming measurement constraints, by setting the minimum width and the maximum width to be equal to the maximum width multiplied by fraction. Modifier Modifier.height(height: Dp) Declare the height of the content to be exactly heightdp. Modifier Modifier.
