Struct FlexColumnWidth 

pub struct FlexColumnWidth {
    pub value: f64,
}

Sizes the column by taking a part of the remaining space once all the other columns have been laid out.

For example, if two columns have a FlexColumnWidth, then half the space will go to one and half the space will go to the other.

This is a cheap way to size a column.

Fields

value: f64

The fraction of the remaining space once all the other columns have been laid out that this column should occupy.

Implementations

impl FlexColumnWidth

pub const fn new(value: f64) -> FlexColumnWidth

Creates a column width based on a fraction of the remaining space once all the other columns have been laid out. Dart’s default value is 1.0.

pub fn default_width() -> TableColumnWidthRef

Dart’s const FlexColumnWidth(), the default column width of a table: one shared value, as Dart’s constant is one object, so a table given the default again is unchanged.

Trait Implementations

impl Debug for FlexColumnWidth

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

Formats the value using the given formatter.

impl TableColumnWidth for FlexColumnWidth

fn min_intrinsic_width( &self, _app: &mut App, _cells: &[AnyRenderBox], _container_width: f64, ) -> f64

The smallest width that the column can have.

fn max_intrinsic_width( &self, _app: &mut App, _cells: &[AnyRenderBox], _container_width: f64, ) -> f64

The ideal width that the column should have. This must be equal to or greater than the min_intrinsic_width. The column might be bigger than this width, e.g. if the column is flexible or if the table’s width ends up being forced to be bigger than the sum of all the max_intrinsic_width values.

fn flex(&self, _app: &mut App, _cells: &[AnyRenderBox]) -> Option<f64>

The flex factor to apply to the cell if there is any room left over when laying out the table. The remaining space is distributed to any columns with flex in proportion to their flex value (higher values get more space).

fn as_any(&self) -> &dyn Any

Downcast support for Dart’s is checks on a column width.
