Options

You can customize the Keyboard by passing options (props) to it. Here are the available options (the code examples are the defaults):

layout

Modify the keyboard layout

layout={{
  'default': [
    '` 1 2 3 4 5 6 7 8 9 0 - = {bksp}',
    '{tab} q w e r t y u i o p [ ] \\',
    '{lock} a s d f g h j k l ; \' {enter}',
    '{shift} z x c v b n m , . / {shift}',
    '.com @ {space}'
  ],
  'shift': [
    '~ ! @ # $ % ^ & * ( ) _ + {bksp}',
    '{tab} Q W E R T Y U I O P { } |',
    '{lock} A S D F G H J K L : " {enter}',
    '{shift} Z X C V B N M < > ? {shift}',
    '.com @ {space}'
  ]
}}

layoutName

Specifies which layout should be used.

layoutName={"default"}

display

Replaces variable buttons (such as {bksp}) with a human-friendly name (e.g.: "delete").

display={{
  '{bksp}': 'delete',
  '{enter}': '< enter',
  '{shift}': 'shift',
  '{s}': 'shift',
  '{tab}': 'tab',
  '{lock}': 'caps',
  '{accept}': 'Submit',
  '{space}': ' ',
  '{//}': ' '
}}

theme

A prop to add your own css classes. You can add multiple classes separated by a space.

theme={"hg-theme-default"}

debug

Runs a console.log every time a key is pressed. Displays the buttons pressed and the current input.

debug={false}

newLineOnEnter

Specifies whether clicking the "ENTER" button will input a newline (\n) or not.

newLineOnEnter={true}

Methods

simple-keybord has a few methods you can use to further control it's behavior. To access these functions, you need a ref of the simple-keyboard component, like so:

<Keyboard
  ref={r => this.keyboard = r}
  [...]
/>

// Then, on componentDidMount ..
this.keyboard.methodName(params);

clearInput

Clear the keyboard's input.

this.keyboard.clearInput();

getInput

Get the keyboard's input (You can also get it from the onChange prop).

let input = this.keyboard.getInput();

setInput

Set the keyboard's input. Useful if you want the keybord to initialize with a default value, for example.

this.keyboard.setInput("Hello World!");

It returns a promise, so if you want to run something after it's applied, call it as so:

let inputSetPromise = this.keyboard.setInput("Hello World!");

inputSetPromise.then((result) => {
  console.log("Input set");
});
