The EditableIntSlider widget allows selecting selecting an integer value within a set bounds using a slider and for more precise control offers an editable number input box.

Discover more on using widgets to add interactivity to your applications in the how-to guides on interactivity. Alternatively, learn how to set up callbacks and (JS-)links between parameters or how to use them as part of declarative UIs with Param.

Parameters:#

For details on other options for customizing the component see the customization guides.

Core#

disabled (boolean): Whether the widget is editable
end (int): The upper bound for the slider, can be overridden by a higher value.
fixed_start (int | None): A fixed lower bound for the slider and input, value cannot exceed this.
fixed_end (int | None): A fixed upper bound for the slider and input, value cannot exceed this.
start (int): The lower bound for the slider, can be overridden by a lower value.
step (int): The interval between values
value (int): The selected value as an int type
value_throttled (int): The selected value as a int type throttled until mouseup

Display#

bar_color (color): Color of the slider bar as a hexadecimal RGB value
direction (str): Whether the slider should go from left to right (‘ltr’) or right to left (‘rtl’)
format (str, bokeh.models.TickFormatter): Formatter to apply to the slider value
label (str): The title of the widget
orientation (str): Whether the slider should be displayed in a ‘horizontal’ or ‘vertical’ orientation.
tooltips (boolean): Whether to display tooltips on the slider handle

Styling#

sx (dict): Component level styling API.
theme_config (dict): Theming API.

Aliases#

For compatibility with Panel certain parameters are allowed as aliases:

button_style: Alias for variant
button_type: Alias for color
name: Alias for label

Basic Usage#

The EditableIntSlider widget allows selecting a integer value in a range defined by the start and end values:

int_slider = pmui.EditableIntSlider(label='Integer Slider', start=0, end=8, step=2, value=4)

int_slider

The value of the widget returns a integer and can be accessed and set like any other widget:

int_slider.value

Fixed Range#

The slider is bounded by the start and end values but the text input fields can exceed end and go below start. If value should be fixed to a certain range it can be set with fixed_start and fixed_end:

pmui.EditableIntSlider(
    label='Fixed Range', start=0, end=8, step=2, value=4, fixed_start=-10, fixed_end=20
)

Format#

A custom format string or bokeh TickFormatter may be used to format the slider values:

from bokeh.models.formatters import PrintfTickFormatter

str_format = pmui.EditableIntSlider(label='Rank', format='0o', start=0, end=100)

tick_format = pmui.EditableIntSlider(label='Count', format=PrintfTickFormatter(format='%d ducks'), start=0, end=100)

pmui.Column(str_format, tick_format)

Label#

You may remove the label/ name by not setting it.

pmui.EditableIntSlider()

Show Value#

You may remove the value label by setting show_value=False.

pmui.EditableIntSlider(show_value=False)

Disabled#

The widget can be disabled with disabled=True.

pmui.EditableIntSlider(label='Int Slider (disabled)', disabled=True)

Color#

You can specify a color.

pmui.FlexBox(*(
    pmui.EditableIntSlider(label=f'Float Slider ({color})', color=color)
    for color in pmui.EditableIntSlider.param.color.objects
))

Sizes#

For smaller slider, use the parameter size="small".

pmui.Row(
    pmui.EditableIntSlider(label='Age Slider', size="small"),
    pmui.EditableIntSlider(label='Age Slider', size="medium"),
)

Custom Marks#

You can have custom marks by providing a rich list to the marks parameter. Note that unlike continuous sliders the value of the marks should be the integer index of the option.

marks = [
  {
    "value": 0,
    "label": '0°C',
  },
  {
    "value": 30,
    "label": '30°C',
  },
  {
    "value": 60,
    "label": '60°C',
  },
  {
    "value": 100,
    "label": '100°C',
  },
]

pmui.EditableIntSlider(marks=marks)

Tooltip always visible#

You can force the thumb label to be always visible with tooltips=True.

pmui.EditableIntSlider(label='Age', tooltips=True, value=42)

Tracks#

The track can be inverted or removed with track="inverted" and track=False respectively:

pmui.Row(
    pmui.EditableIntSlider(label='Age Slider', value=42, track="inverted"),
    pmui.EditableIntSlider(label='Age Slider', value=42, track=False)
)

Vertical Sliders#

The orientation of a slider may be “vertical”:

pmui.EditableIntSlider(label='Age Slider', value=42, orientation="vertical")

API Reference#

The EditableIntSlider widget exposes a number of options which can be changed from both Python and Javascript. Try out the effect of these parameters interactively:

pmui.EditableIntSlider().api(jslink=True)
