bokeh.models.widgets.sliders¶

Various kinds of slider widgets.

class AbstractSlider(**kwargs)[source]¶

Bases: bokeh.models.widgets.widget.Widget

Note

This is an abstract base class used to help organize the hierarchy of Bokeh model types. It is not useful to instantiate on its own.

bar_color¶: property type: Color

callback¶

property type: Instance ( Callback )

A callback to run in the browser whenever the current Slider value changes.

DEPRECATED: use .js_on_change or .on_change with “value” or “value_throttled”

callback_policy¶

property type: Enum ( SliderCallbackPolicy )

When the value_throttled property is updated.

This parameter can take on only one of three options:

“continuous”: the callback will be executed immediately for each movement of the slider
“throttle”: the callback will be executed at most every callback_throttle milliseconds.
“mouseup”: the callback will be executed only once when the slider is released.

The “mouseup” policy is intended for scenarios in which the callback is expensive in time.

Both Python and JS callbacks on “value_throttled” will respect this policy setting.

callback_throttle¶

property type: Float

Number of milliseconds to pause between callback calls as the slider is moved.

direction¶: property type: Enum ( Enumeration(ltr, rtl) )

format¶: property type: String

show_value¶

property type: Bool

Whether or not show slider’s value.

title¶

property type: String

Slider’s label.

tooltips¶: property type: Bool
