Functions

fun Modifier.weight(
        @FloatRange(from = 0.0, fromInclusive = false) weight: Float,
        fill: Boolean = true,
    ): Modifier

Size the element's width proportional to its weight relative to other weighted sibling elements in the Row. The parent will divide the horizontal space remaining after measuring unweighted child elements and distribute it according to this weight. When fill is true, the element will be forced to occupy the whole width allocated to it. Otherwise, the element is allowed to be smaller - this will result in Row being smaller, as the unused allocated width will not be redistributed to other siblings.

Parameters


weight	The proportional width to give to this element, as related to the total of all weighted siblings. Must be positive.
fill	When `true`, the element will occupy the whole width allocated.

fun Modifier.align(alignment: Alignment.Vertical): Modifier

Align the element vertically within the Row. This alignment will have priority over the Row's verticalAlignment parameter.

fun Modifier.alignBy(alignmentLine: HorizontalAlignmentLine): Modifier

Position the element vertically such that its alignmentLine aligns with sibling elements also configured to alignBy. alignBy is a form of align, so both modifiers will not work together if specified for the same layout. alignBy can be used to align two layouts by baseline inside a Row, using alignBy(FirstBaseline). Within a Row, all components with alignBy will align vertically using the specified HorizontalAlignmentLines or values provided using the other alignBy overload, forming a sibling group. At least one element of the sibling group will be placed as it had Alignment.Top align in Row, and the alignment of the other siblings will be then determined such that the alignment lines coincide. Note that if only one element in a Row has the alignBy modifier specified the element will be positioned as if it had Alignment.Top align.

fun Modifier.alignByBaseline(): Modifier

Position the element vertically such that its first baseline aligns with sibling elements also configured to alignByBaseline or alignBy. This modifier is a form of align, so both modifiers will not work together if specified for the same layout. alignByBaseline is a particular case of alignBy. See alignBy for more details.

fun Modifier.alignBy(alignmentLineBlock: (Measured) -> Int): Modifier

Position the element vertically such that the alignment line for the content as determined by alignmentLineBlock aligns with sibling elements also configured to alignBy. alignBy is a form of align, so both modifiers will not work together if specified for the same layout. Within a Row, all components with alignBy will align vertically using the specified HorizontalAlignmentLines or values obtained from alignmentLineBlock, forming a sibling group. At least one element of the sibling group will be placed as it had Alignment.Top align in Row, and the alignment of the other siblings will be then determined such that the alignment lines coincide. Note that if only one element in a Row has the alignBy modifier specified the element will be positioned as if it had Alignment.Top align.
