For a complete list of the GUI widgets available to you, you can list the registered widget types. Widget and DOMWidget, not listed below, are base classes.

There are 8 widgets distributed with IPython that are designed to display numeric values. Widgets exist for displaying integers and floats, both bounded and unbounded. The integer widgets share a similar naming scheme to their floating point counterparts. By replacing Float with Int in the widget name, you can find the Integer equivalent.

widgets.IntSlider(
value=7,
min=0,
max=10,
step=1,
description='Test:',
disabled=False,
continuous_update=False,
orientation='horizontal',
readout=True,
readout_format='i',

)
Sliders can also be displayed vertically.

There are three widgets that are designed to display a boolean value.
In [13]:
widgets.ToggleButton(
value=False,
description='Click me',
disabled=False,
button_style='', # 'success', 'info', 'warning', 'danger' or ''
tooltip='Description',
icon='check'
)
In [14]:
widgets.Checkbox(
value=False,
description='Check me',
disabled=False
)
In [15]:
widgets.Valid(
value=False,
description='Valid!',
disabled=False
)
There are four widgets that can be used to display single selection lists, and one that can be used to display multiple selection lists. All inherit from the same base class. You can specify the enumeration of selectable options by passing a list. You can also specify the enumeration as a dictionary, in which case the keys will be used as the item displayed in the list and the corresponding value will be returned when an item is selected.
In [16]:
widgets.Dropdown(
options=['1', '2', '3'],
value='2',
description='Number:',
disabled=False,
button_style='' # 'success', 'info', 'warning', 'danger' or ''
)
The following is also valid:
In [17]:
widgets.Dropdown(
options={'One': 1, 'Two': 2, 'Three': 3},
value=2,
description='Number:',
)
In [18]:
widgets.RadioButtons(
options=['pepperoni', 'pineapple', 'anchovies'],
# value='pineapple',
description='Pizza topping:',
disabled=False
)
In [19]:
widgets.Select(
options=['Linux', 'Windows', 'OSX'],
# value='OSX',
description='OS:',
disabled=False
)
In [20]:
widgets.SelectionSlider(
options=['scrambled', 'sunny side up', 'poached', 'over easy'],
value='sunny side up',
description='I like my eggs ...',
disabled=False,
continuous_update=False,
orientation='horizontal',
readout=True,
# readout_format='i',
# slider_color='black'
)
In [21]:
widgets.ToggleButtons(
options=['Slow', 'Regular', 'Fast'],
description='Speed:',
disabled=False,
button_style='', # 'success', 'info', 'warning', 'danger' or ''
tooltip='Description',
# icon='check'
)
In [22]:
widgets.SelectMultiple(
options=['Apples', 'Oranges', 'Pears'],
value=['Oranges'],
description='Fruits',
disabled=False
)
There are 4 widgets that can be used to display a string value. Of those, the Text and Textarea widgets accept input. The Label and HTML widgets display the string as either Label or HTML respectively, but do not accept input.
In [23]:
widgets.Text(
value='Hello World',
placeholder='Type something',
description='String:',
disabled=False
)
In [24]:
widgets.Textarea(
value='Hello World',
placeholder='Type something',
description='String:',
disabled=False
)
In [25]:
widgets.Label(
value="$$\\frac{n!}{k!(n-k)!} = \\binom{n}{k}$$",
placeholder='Some LaTeX',
description='Some LaTeX',
disabled=False
)
In [26]:
widgets.HTML(
value="Hello <b>World</b>",
placeholder='Some HTML',
description='Some HTML',
disabled=False
)
In [27]:
file = open("images/WidgetArch.png", "rb")
image = file.read()
widgets.Image(
value=image,
format='png',
width=300,
height=400
)
In [28]:
widgets.Button(
description='Click me',
disabled=False,
button_style='', # 'success', 'info', 'warning', 'danger' or ''
tooltip='Click me',
icon='check'
)
The Play widget is useful to perform animations by iterating on a sequence of integers with a certain speed.
In [29]:
play = widgets.Play(
# interval=10,
value=50,
min=0,
max=100,
step=1,
description="Press play",
disabled=False
)
slider = widgets.IntSlider()
widgets.jslink((play, 'value'), (slider, 'value'))
widgets.HBox([play, slider])
In [30]:
widgets.ColorPicker(
concise=False,
description='Pick a color',
value='blue'
)
In [31]:
widgets.Controller(
index=0,
)
In [32]:
items = [widgets.Label(str(i)) for i in range(4)]
widgets.HBox(items)
In [33]:
items = [widgets.Label(str(i)) for i in range(4)]
widgets.HBox([widgets.VBox([items[0], items[1]]), widgets.VBox([items[2], items[3]])])
In [34]:
accordion = widgets.Accordion(children=[widgets.IntSlider(), widgets.Text()])
accordion.set_title(0, 'Slider')
accordion.set_title(1, 'Text')
accordion
In [35]:
list = ['P0', 'P1', 'P2', 'P3', 'P4']
children = [widgets.Text(description=name) for name in list]
tab = widgets.Tab(children=children)
