ui::LinearGradientBrush¶

Header: winui/render/Brush.hpp.

A linear gradient running along one GradientAxis of the painted bounds.

Flat-color drawing keeps taking a plain Color. A control that wants gradient chrome passes one of these to Renderer::fill_rounded_rect_gradient(), and a Shape takes it as one alternative of Brush.

Example:

const ui::LinearGradientBrush luna{
    .stops = {{0.0f, ui::Color::from_rgba(255, 255, 255)},
              {1.0f, ui::Color::from_rgba(214, 208, 197)}},
};
renderer.fill_rounded_rect_gradient(ui::Rect{0, 0, 75, 23}, 3.0f, luna);

auto rect = std::make_unique<ui::RectangleControl>();
rect->set_fill(ui::LinearGradientBrush{.stops = luna.stops, .axis = ui::GradientAxis::Horizontal});

Field	Type	Default
`stops`	`GradientStops`		The color stops, in increasing `offset` order. Empty paints nothing.
`axis`	`GradientAxis`	`GradientAxis::Vertical`	The direction the stops run; Vertical by default.
