scroll

scroll :: (
    style: Style = .{},
    axis: Axis = .VERTICAL,
    loc := #caller_location
) -> Container

A column whose content scrolls vertically (horizontally with axis = .HORIZONTAL) when it is larger than the space it is given. Give it grow = 1 or a fixed size.

Parameters

style: Style = .{}

layout and paint options for the container.

axis: Axis = .VERTICAL

the scrolling direction.

loc := #caller_location

the call site. It identifies the widget from one frame to the next, so leave the default.

    for scroll(.{ height = 100 }) {
