Struct unsegen::widget::widget::Demand2D

pub struct Demand2D {
    pub width: ColDemand,
    pub height: RowDemand,
}

A two dimensional (rectangular) Demand (composed of Demands for columns and rows).

Fields

width: ColDemand

height: RowDemand

Implementations

impl Demand2D

pub fn add_vertical(self, other: Self) -> Self

Combine two Demand2Ds by accumulating the height and making the width accommodate both.

This is useful two compute the combined Demand2D of two widgets arranged on top of each other.

Examples:

use unsegen::base::*;
use unsegen::widget::*;

let d1 = Demand2D {
    width: ColDemand::exact(5),
    height: RowDemand::exact(5),
};
let d2 = Demand2D {
    width: ColDemand::at_least(2),
    height: RowDemand::from_to(3, 5),
};

assert_eq!(
    d1.add_vertical(d2),
    Demand2D {
        width: ColDemand::at_least(5),
        height: RowDemand::from_to(8, 10),
    }
);

pub fn add_horizontal(self, other: Self) -> Self

Combine two Demand2Ds by accumulating the width and making the height accommodate both.

This is useful two compute the combined Demand2D of two widgets arranged on top of each other.

Examples:

use unsegen::base::*;
use unsegen::widget::*;

let d1 = Demand2D {
    width: ColDemand::exact(5),
    height: RowDemand::exact(5),
};
let d2 = Demand2D {
    width: ColDemand::at_least(2),
    height: RowDemand::from_to(3, 5),
};

assert_eq!(
    d1.add_horizontal(d2),
    Demand2D {
        width: ColDemand::at_least(7),
        height: RowDemand::exact(5),
    }
);
