Example Usage:

import React, { useState } from 'react';
import { TextField } from '@mui/material';
import { MuiKeyboard } from '@autosys/react-mui-keyboard';
import { russianButtons, englishButtons, numbers } from 'path_to_your_button_data';

const App = () => {
  const [checked, setChecked] = useState(false);
  const [inputValue, setInputValue] = useState<string>('');

  const handleUrlChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    setInputValue(event.target.value);
  };

  const handleChange = () => {
    setChecked((prev) => !prev);
  };

  return (
    <MuiKeyboard
      textField={
        <TextField
          onChange={handleUrlChange}
          onClick={handleChange}
          value={inputValue}
          fullWidth
          multiline
        />
      }
      slide
      direction="up"
      checked={checked}
      setInputValue={setInputValue}
      numbers={numbers}
      firstLanguage={russianButtons}
      secondLanguage={englishButtons}
      secondLangLabel="EN"
      firstLangLabel="RU"
      keyboardWidth={'900px'}
      buttonSize="medium"
      labelLangButton
      reverseButton
      sx={{ display: 'flex' }}
    />
  );
};

export default App;

Usage without TextField and with Context

If you want to use the MuiKeyboard component without a built-in TextField and manage the input value using context, follow these steps:

1. Wrap your application with the MuiKeyboardProvider:

// index.tsx
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import { MuiKeyboardProvider } from '@autosys/react-mui-keyboard';
import { russianButtons } from '@autosys/react-mui-keyboard';

ReactDOM.render(
  <MuiKeyboardProvider
    firstLanguage={russianButtons}
    sx={{ display: 'flex', justifyContent: 'center', mt: 50 }}
    keyboardWidth={'900px'}
  >
    <App />
  </MuiKeyboardProvider>,
  document.getElementById('root'),
);

2. Then yo may use the useMuiKeyboard hook in any another component to access the input value and setter from the context.

// App.tsx
import React from 'react';
import { TextField } from '@mui/material';
import { useMuiKeyboard } from '@autosys/react-mui-keyboard';

const App = () => {
  const { inputValue, keyboardFeature } = useMuiKeyboard();
  return (
    <TextField
      value={inputValue}
      onClick={() => keyboardFeature({ slideEffect: true })}
      label="Click!"
    >
      Hello
    </TextField>
  );
};

export default App;

If you want your component (for example, a button) to only be able to close the keyboard, use onClick={() => keyboardFeature({ slideEffect: false })}

If you want to reset the inputValue, but don't want to do it with a button on the keyboard, you can use any other button with onClick={() => keyboardFeature({ resetText: true })}

Examples:

singlyBack and betweenButtons

If you want the backspace key to be separate, use the singlyBack prop. You can also use the betweenButtons prop to increase the distance between the keys.

labelLetterButton

If you want to use numbers separately from letters, then use the labelLetterButton prop. You can also use the numberColumns and numbersRows props to change columns and rows in a numeric block.
