react-material-ui-keyboard-no-touch-tap

Virtual keyboard for TextField when needed. Forked from react-material-ui-keyboard for use with material-ui@0.20.4 in 6.2.1, but our company had to fork material-ui into velocity-mui, so from v6.3.0 on, this package uses velocity-mui latest because we forked it for future upgrades to react and bug fixes we found.

You controll when to open it which allows cross platform App optimizations and code reusability for diferent platoforms such as Progressive Web Apps, Hybrid Apps, Electron Apps, Touch Devices, Smart TVs, Desktops, and all other Compatible JavaScript Enviroments.

You have the freedom to choose on which of them to open the Keyboard and on which to just use a textField!

Properties

NameTypeDefaultDescription
automaticboolIf true, keyboard will automaticlly: open when textField gets focused and close instead of firing onRequestClose.
disableEffectsboolIf true, disables all effects (ripples, focus, hover) on all keyboardKeys
openboolControls whether the Keyboard is opened or not.
layouts*string[][][]Keybaord layouts that can be changed when user clicks on 'Keyboard' key.
keyboardKeyWidthnumberthis.context.muiThemet.button.minWidthOverride keyboard key's max width.
keyboardKeyHeightnumberthis.context.muiThemet.button.heightOverride keyboard key's max height.
keyboardKeySymbolSizenumberthis.context.muiThemet.flatButton.fontSizeOverride keyboard key's max symbol size.
textField*elementInput field used when keyboard is closed and cloned when it's opened.
onRequestClosefunctionFired when keyboard recives 'Enter' or 'Escape' eighter from onKeyDown listener or keyboard key touch/click event.
onInputfunctionFired when keyboard recives 'Enter' Signature: function(input: string) => void.
onInputValueChangefunctionFired when keyboard's input chages value Signature: function(input: string) => void.
correctorNamestringName of the cloned textField prop to which to bind corrector.
corrector**functionFunction which is bound to the the cloned textField at correctorName prop. this is bound to the Keyboard, public method makeCorrection can be used to apply a correction to the keyboard input.

Props marked with * are required.

** corrector is required when correctorName is provided.

Requirements

textField must be a controlled input

Node passed to textField Prop must support the following props:

  • value* of type string
  • readOnly* of type bool

Props marked with * must be passed down to the native input element.

Implementation

react-material-ui-keyboard is implemented using the followong Material-Ui Elements

  • Dialog
  • FlatButtton
  • SVG Icons

and uses React.cloneElement to clone textFiled for the kyboard input field.

The used Dialog is modal which guaranties that only one keyboard can be opened which allows memory and performance optimizations.

Keyboard Compoment uses MuiTheme, props, window.innerWidth and window.innerHeight information to calculate it's size and keyboard keys size (width x height) to ensure it always fits best on screen chech GALLERY.

Key Support

Included Layouts

The following keyboard layouts are exported from 'react-material-ui-keyboard/layouts'

numericKeyboard

const numericKeyboard = [
  ["Escape", "-", "Backspace"],
  ["7", "8", "9"],
  ["4", "5", "6"],
  ["1", "2", "3"],
  ["0", ".", "Enter"],
];

alphaNumericKeyboard

const alphaNumericKeyboard = [
  ["1", "2", "3", "4", "5", "6", "7", "8", "9", "0"],
  ["q", "w", "e", "r", "t", "y", "u", "i", "o", "p"],
  ["a", "s", "d", "f", "g", "h", "j", "k", "l", "Backspace"],
  ["Escape", "CapsLock", "z", "x", "c", "v", "b", "n", "m", "Enter"],
];

Check supported keys!

If a key you want to use is not supported open an Issue.

Public methods

Keyboard exposes public method makeCorrection which can be used to apply keyboard input value corrections when keyboard is opened or within correction handller.

Public members

Keyboard has one public static member which is designed to be overwritten: automaitcOpenPredicate it's signature is function() => boolean. It is called when automatic is true and the attached onFocus handler on textField gets fired to determinate should keyboard open and disable the native virtual keyboard by assigning readOnly at textField in the render. Default automaitcOpenPredicate behaviour is to always return true. You can override it to change when to automaticlly open keyboard onFocus.

Examples

import * as React from "react";
import TextField from "material-ui/TextField";
import Keyboard from "react-material-ui-keyboard";
import { extendedKeyboard } from "react-material-ui-keyboard/layouts";

class Demo extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      open: false,
      value: "",
    };
    this.onInput = this.handleInput.bind(this);
  }

  handleInput(input) {
    this.setState({ value: input });
  }

  render() {
    <Keyboard
      textField={<TextField id="text" value={this.state.value} />}
      automatic
      onInput={this.onInput}
      layouts={[extendedKeyboard]}
    />;
  }
}

Example using custom textField and controlling when to open the keyboard and when to prevent the native virtual keyboard

import * as React from "react";
import NumberInput from "material-ui-number-input";
import Keyboard from "react-material-ui-keyboard";
import { numericKeyboard } from "react-material-ui-keyboard/layouts";

function corrector(value) {

    this.state = { open: false, value: "2" };
    this.onFocus = this.handleFocus.bind(this);
    this.onChange = this.handleChange.bind(this);
    this.onRequestClose = this.handleRequestClose.bind(this);
    this.onInput = this.handleInput.bind(this);
    this.onError = this.handleError.bind(this);
    this.onValid = this.handleValid.bind(this);
  }

  canOpenKeyboard() {
    return this.state.value.length % 2 === 0;

    this.setState({ value: value });
  }

  handleRequestClose() {

    this.setState({ errorText: errorText });
  }

  handleValid(value) {
    console.debug(`valid ${value}`);
  }

  componentDidMount() {
    setTimeout(() => this.setState({ value: "89" }), 1000);
  }

  render() {
    const { state, onFocus, onChange, onError, onValid, onInput } = this;
    const { value, errorText } = state;
    const textField = (
      <NumberInput
        id="num"
        required
        value={value}
        min={-10}
        max={12}
        strategy="warn"
        errorText={errorText}
        onFocus={onFocus}

        onError={onError}
        onValid={onValid}
        floatingLabelText="Click for a Keyboard"
      />
    );

    return (
      <Keyboard
        textField={textField}
        open={this.state.open}
        onRequestClose={this.onRequestClose}
        onInput={onInput}

Supports propTypes for regular JavaScript users

It is possible to use react-material-ui-keyboard in none material-ui project.

Limitations

If you need to change theme eg. gutter, spacing, colors or any other option you need to wrapp <Keyboard ... /> in MuiThemeProvider or to manually provide a muiTheme to parent's context.
