Marker

Marker #

Bases: Control

A marker displayed on the Map at the specified location through the MarkerLayer.

RAISES DESCRIPTION
AssertionError

If the content is not visible, or if height or width are negative.

alignment #

alignment: Alignment | None = None

Alignment of the marker relative to the normal center at coordinates.

Defaults to the value of the parent MarkerLayer.alignment.

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.

/// details | Dimensions type: info | Breakpoint | Dimension | |---|---| | xs | <576px | | sm | ≥576px | | md | ≥768px | | lg | ≥992px | | xl | ≥1200px | | xxl | ≥1400px | ///

content #

content: Control

The content to be displayed at coordinates.

Note

Must be provided and visible.

coordinates #

coordinates: MapLatitudeLongitude

The coordinates of the marker.

This will be the center of the marker, if alignment is Alignment.CENTER.

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.

/// details | Example type: 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.

height #

height: Number = 30.0

The height of the content Control.

Note

Must be non-negative.

key #

key: KeyValue | None = None

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 | BasePage | None

The page 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.

rotate #

rotate: bool | None = None

Whether to counter rotate this marker to the map's rotation, to keep a fixed orientation. So, when True, this marker will always appear upright and vertical from the user's perspective.

If None, defaults to the value of the parent MarkerLayer.rotate.

Note

This is not used to apply a custom rotation in degrees to this marker.

rtl #

rtl: bool = False

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

tooltip #

tooltip: TooltipValue | None = None

The tooltip ot show when this control is hovered over.

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 = 30.0

The width of the content Control.

Note

Must be non-negative.

before_event #
