ipymaterialui

Jupyter Widgets based on Material-UI which implement Google's Material Design Spec with React.

Installation

Prerequisites: https://ipywidgets.readthedocs.io/en/stable/user_install.html

To install use pip:

$ pip install ipymaterialui
$ jupyter labextension install jupyter-materialui             # for lab

For a development installation (requires npm),

$ git clone https://github.com/maartenbreddels/ipymaterialui.git
$ cd ipymaterialui
$ pip install -e .
$ jupyter nbextension install --py --symlink --sys-prefix ipymaterialui
$ jupyter nbextension enable --py --sys-prefix ipymaterialui
$ jupyter labextension install ./js

Usage

For examples see the example notebook.

The Material-UI documentation can be used to find all available components and attributes (on the left side bar). Click the <> icon to see the source code of the examples. Scroll to the bottom of the page to access a link to the API of the component. Ipymaterialui tries to stay close to the React and Material-UI API, but the syntax is different:

	Description	Material-UI	ipymaterialui
1	Components are classes instead of HTML	<Button .../>	Button(...)
2	Child components and text are defined in the children traitlet	<Button>text <Icon .../></Button>	Button(children=['text', Icon(...)])
3	Flag attributes require a boolean value	<Container fixed ...	Container(fixed=True ...
4	Attributes are snake_case	<Button fullWidth ..	Button(full_width=True ...
5	No onChange handler necessary, use observe. Note that the main value is not always value like in ipywidgets (e.g. checked or selected)	<Switch onChange="..."	mySwitch.checked
6	Event listeners are defined with on_event	<Button onClick={someMethod}' ...	button.on_event('onClick', some_method)
			def some_method(widget, event, data):
7	Regular HTML tags can made with the Html class	<div>...</div>	Html(tag='div', children=[...])
8	The attributes class and style need to be suffixed with an underscore	<Button class="mr-3" style="..." >	Button(class_='mr-3', style_={...})
9	Icon uses the lowercase name from Material icons	<AlarmOnIcon .../>	Icon(children='alarm_on' ...)

Examples

Aspect 1, 2, 3, 4, 6, 8 and 9

This example demonstrates aspect 1, 2, 3, 4, 6, 8 and 9 of the table above.

React/Material-UI

const useStyles = makeStyles(theme => ({                      (8)
    alarmOnIcon: {
        marginRight: theme.spacing(1),
    },
}));

export default function MyButton() {
    const classes = useStyles();                              (8)
    const [btnText, setBtnText] = React.useState('Primary');  (6)

    function someMethod() {                                   (6)
        setBtnText(() => new Date().toLocaleTimeString());
    }

    return (
        (1)                                         (3)(4)      (6)          
        <Button variant="contained" color="primary" centerRipple onClick={someMethod}>
            (2)(9)       (8)
            <AlarmOnIcon className={classes.alarmOnIcon}/>
            {btnText}
        </Button>
    );
}

ipymaterialui

import ipymaterialui as mui
import datetime
             (1)                                          (3)(4)              (2)
button = mui.Button(variant='contained', color='primary', center_ripple=True, children=[
             (8)                                      (9)
    mui.Icon(style_={'marginRight': '8px'}, children='alarm_on'),
    'Primary'
])

def some_method(widget, event, data):                 (6)
    time = datetime.datetime.now().strftime("%X")
    button.children = [button.children[0], time]

button.on_event('onClick', some_method)               (6)
button

Aspect 5

This example demonstrates aspect 5 of the table above.

React/Material-UI

export default function MySwitch() {
    const [state, setState] = React.useState(true);

    const handleChange = event => {
        setState(event.target.checked);
    };
    
    return (
        <Switch
            checked={state}
            onChange={handleChange}
        />
    );
}

ipymaterialui

import ipymaterialui as mui

mui.Switch(checked=True)

Aspect 7

This example demonstrates aspect 7 of the table above.

React/Material-UI

export default function MyHtml() {
    return (
        <div>some HTML</div>
    );
}

ipymaterialui

import ipymaterialui as mui

mui.Html(tag='div', children='some HTML')
