|
|
Parameters:
|
|
minimum: minimum value for slider.
|
|
maximum: maximum value for slider.
|
|
value: default value for slider. If a function is provided, the function will be called each time the app loads to set the initial value of this component. Ignored if randomized=True.
|
|
step: increment between slider values.
|
|
label: the label for this component, displayed above the component if `show_label` is `True` and is also used as the header if there are a table of examples for this component. If None and used in a `gr.Interface`, the label will be the name of the parameter this component corresponds to.
|
|
info: additional component description, appears below the label in smaller font. Supports markdown / HTML syntax.
|
|
every: Continously calls `value` to recalculate it if `value` is a function (has no effect otherwise). Can provide a Timer whose tick resets `value`, or a float that provides the regular interval for the reset Timer.
|
|
inputs: Components that are used as inputs to calculate `value` if `value` is a function (has no effect otherwise). `value` is recalculated any time the inputs change.
|
|
show_label: if True, will display label.
|
|
container: If True, will place the component in a container - providing some extra padding around the border.
|
|
scale: relative size compared to adjacent Components. For example if Components A and B are in a Row, and A has scale=2, and B has scale=1, A will be twice as wide as B. Should be an integer. scale applies in Rows, and to top-level Components in Blocks where fill_height=True.
|
|
min_width: minimum pixel width, will wrap if not sufficient screen space to satisfy this value. If a certain scale value results in this Component being narrower than min_width, the min_width parameter will be respected first.
|
|
interactive: if True, slider will be adjustable; if False, adjusting will be disabled. If not provided, this is inferred based on whether the component is used as an input or output.
|
|
visible: If False, component will be hidden.
|
|
elem_id: An optional string that is assigned as the id of this component in the HTML DOM. Can be used for targeting CSS styles.
|
|
elem_classes: An optional list of strings that are assigned as the classes of this component in the HTML DOM. Can be used for targeting CSS styles.
|
|
render: If False, component will not render be rendered in the Blocks context. Should be used if the intention is to assign event listeners now but render the component later.
|
|
key: if assigned, will be used to assume identity across a re-render. Components that have the same key across a re-render will have their value preserved.
|
|
randomize: If True, the value of the slider when the app loads is taken uniformly at random from the range given by the minimum and maximum.
|
|
show_reset_button: if False, will hide button to reset slider to default value.
