Axis 继承自： Enum

二维空间中的两个基本方向。

坐标轴始终相对于当前的坐标空间。也就是说，例如，由于对场景应用了某个局部变换， 一个 [horizontal] 坐标轴实际上可能呈现为从右上到左下的对角线方向。

示例

import flet as ft


def showcase_card(axis: ft.Axis) -> ft.Container:
    return ft.Container(
        width=350 if axis == ft.Axis.HORIZONTAL else 220,
        padding=12,
        border=ft.Border.all(1, ft.Colors.RED),
        border_radius=10,
        bgcolor=ft.Colors.SURFACE_CONTAINER_LOW,
        content=ft.Column(
            spacing=8,
            horizontal_alignment=ft.CrossAxisAlignment.CENTER,
            controls=[
                ft.Text(axis.name, weight=ft.FontWeight.BOLD),
                ft.SegmentedButton(
                    direction=axis,
                    selected=["medium"],

                        ft.Segment(value="large", label="Large"),
                    ],

                controls=[
                    ft.Text("Compare horizontal vs vertical segment layout."),
                    ft.Row(

                        controls=[showcase_card(axis) for axis in ft.Axis],
                    ),
                ]
            )
        )
    )


if __name__ == "__main__":
    ft.run(main)
