autofocus

autofocus: bool | None = None

True if the control will be selected as the initial focus. If there is more than one control on a page with autofocus set, then the first one added to the page will get focus.

badge

badge: BadgeValue | None = None

A badge to show on top of this control.

bgcolor

bgcolor: ColorValue | None = None

Button's background color.

Note

If both bgcolor and style.bgcolor are provided, bgcolor value will be used.

Effective only if this control is a descendant of one of the following: Stack control, Page.overlay list.

clip_behavior

clip_behavior: ClipBehavior | None = None

The content will be clipped (or not) according to this option.

Defaults to ClipBehavior.NONE.

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

Note

If both color and style.color are provided, color value will be used.

content

content: StrOrControl | None = None

A Control representing custom button content.

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()

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.

Note

Effective only if this control is a descendant of one of the following: Stack control, Page.overlay list.

offset

offset: OffsetValue | None = None

Applies a translation transformation before painting the control.

The translation is expressed as an Offset scaled to the control's size. So, Offset(x=0.25, y=0), for example, will result in a horizontal translation of one quarter the width of this control.

Example

The following example displays container at 0, 0 top left corner of a stack as transform applies -1 * 100, -1 * 100 (offset * control's size) horizontal and vertical translations to the control:

import flet as ft

def main(page: ft.Page):
    page.add(
        ft.Stack(
            width=1000,
            height=1000,
            controls=[
                ft.Container(
                    bgcolor="red",
                    width=100,
                    height=100,
                    left=100,
                    top=100,
                    offset=ft.Offset(-1, -1),
                )
            ],
        )
    )

ft.run(main)

on_animation_end

on_animation_end: (
    ControlEventHandler[ConstrainedControl] | None
) = None

Can be used to chain multiple animations.

The data property of the event handler argument contains the name of the animation.

More information here.

on_blur

on_blur: ControlEventHandler[ElevatedButton] | None = None

Called when the control has lost focus.

on_click

on_click: ControlEventHandler[ElevatedButton] | None = None

Called when a user clicks the button.

on_focus

on_focus: ControlEventHandler[ElevatedButton] | None = None

Called when the control has received focus.

on_hover

on_hover: ControlEventHandler[ElevatedButton] | None = None

Called when a mouse pointer enters or exists the button response area. data property of event object contains true (string) when cursor enters and false when it exits.

Example

import flet as ft

def main(page: ft.Page):
    def on_hover(e):
        e.control.bgcolor = "orange" if e.data == "true" else "yellow"
        e.control.update()

    page.add(
        ft.ElevatedButton(
            "I'm changing color on hover", bgcolor="yellow", on_hover=on_hover
        )
    )

ft.run(main)

on_long_press

on_long_press: (
    ControlEventHandler[ElevatedButton] | None
) = None

Called when the button is long-pressed.

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.

right

right: Number | None = None

The distance that the child's right edge is inset from the right of the stack.

Note

Effective only if this control is a descendant of one of the following: Stack control, Page.overlay list.

rotate

rotate: RotateValue | None = None

Transforms this control using a rotation around its center.

The value of rotate property could be one of the following types:

• number - a rotation in clockwise radians. Full circle 360° is math.pi * 2 radians, 90° is pi / 2, 45° is pi / 4, etc.
• Rotate - allows to specify rotation angle as well as alignment - the location of rotation center.

Example

For example:

ft.Image(
    src="https://picsum.photos/100/100",
    width=100,
    height=100,
    border_radius=5,
    rotate=Rotate(angle=0.25 * pi, alignment=ft.Alignment.CENTER_LEFT)
)

rtl

rtl: bool = False

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

scale

scale: ScaleValue | None = None

Scales this control along the 2D plane. Default scale factor is 1.0, meaning no-scale.

Setting this property to 0.5, for example, makes this control twice smaller, while 2.0 makes it twice larger.

Different scale multipliers can be specified for x and y axis, by setting Control.scale property to an instance of Scale class. Either scale or scale_x and scale_y could be specified, but not all of them.

Example

ft.Image(
    src="https://picsum.photos/100/100",
    width=100,
    height=100,
    border_radius=5,
    scale=ft.Scale(scale_x=2, scale_y=0.5)
)

url_target: UrlTarget | None = None

Where to open URL in the web mode.

Defaults to UrlTarget.BLANK.

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.
