VerticalDivider

Bases: Control

A thin vertical line, with padding on either side.

In the material design language, this represents a divider.

badge

badge: BadgeValue | None = None

A badge to show on top of this control.

col

col: ResponsiveNumber = 12

If a parent of this control is a ResponsiveRow, this property is used to determine how many virtual columns of a screen this control will span.

Can be a number or a dictionary configured to have a different value for specific breakpoints, for example col={"sm": 6}.

This control spans the 12 virtual columns by default.

Dimensions

Breakpoint	Dimension
xs	<576px
sm	≥576px
md	≥768px
lg	≥992px
xl	≥1200px
xxl	≥1400px

color

color: ColorValue | None = None

The color to use when painting the line.

If None, DividerTheme.color is used. If that's is also None, defaults to Theme.divider_color.

data

data: Any = skip_field()

Arbitrary data of any type.

disabled

disabled: bool = False

Every control has disabled property which is False by default - control and all its children are enabled.

Note

The value of this property will be propagated down to all children controls recursively.

Example

For example, if you have a form with multiple entry controls you can disable them all together by disabling container:

ft.Column(
    disabled = True,
    controls=[
        ft.TextField(),
        ft.TextField()
    ]
)

expand

expand: bool | int | None = None

Specifies whether/how this control should expand to fill available space in its parent layout.

More information here.

Note

Has effect only if the direct parent of this control is one of the following controls, or their subclasses: Column, Row, View, Page.

expand_loose

expand_loose: bool = False

Allows the control to expand along the main axis if space is available, but does not require it to fill all available space.

More information here.

Note

If expand_loose is True, it will have effect only if:

• expand is not None and
• the direct parent of this control is one of the following controls, or their subclasses: Column, Row, View, Page.

key

key: (
    str | int | float | bool | ValueKey | ScrollKey | None
) = None

leading_indent

leading_indent: Number | None = None

The amount of empty space to the leading edge of the divider.

If None, DividerTheme.leading_indent is used. If that's is also None, defaults to 0.0.

opacity

opacity: Number = 1.0

Defines the transparency of the control.

Value ranges from 0.0 (completely transparent) to 1.0 (completely opaque without any transparency).

page

page: Page | PageView | None

The page (of type Page or PageView) to which this control belongs to.

parent

parent: BaseControl | None

The direct ancestor(parent) of this control.

It defaults to None and will only have a value when this control is mounted (added to the page tree).

The Page control (which is the root of the tree) is an exception - it always has parent=None.

rtl

rtl: bool = False

Whether the text direction of the control should be right-to-left (RTL).

thickness

thickness: Number | None = None

The thickness of this divider.

Note

A divider with a thickness of 0.0 is always drawn as a line with a width of exactly one device pixel.

If None, DividerTheme.thickness is used. If that's is also None, defaults to 0.0.

tooltip

tooltip: TooltipValue | None = None

The tooltip ot show when this control is hovered over.

trailing_indent

trailing_indent: Number | None = None

The amount of empty space to the trailing edge of the divider.

If None, DividerTheme.trailing_indent is used. If that's is also None, defaults to 0.0.

visible

visible: bool = True

Every control has visible property which is True by default - control is rendered on the page. Setting visible to False completely prevents control (and all its children if any) from rendering on a page canvas. Hidden controls cannot be focused or selected with a keyboard or mouse and they do not emit any events.

width

width: Number | None = None

The divider's width. The divider itself is always drawn as a vertical line that is centered within the width specified by this value.

If None, DividerTheme.space is used. If that's is also None, defaults to 16.0.

before_event

before_event(e: ControlEvent)

before_update

before_update()

clean

clean() -> None

did_mount

did_mount()

init

init()

is_isolated

is_isolated()

update

update() -> None

will_unmount

will_unmount()
