Crash

[mischnic]

Code:

class Notepad extends Component {
  state = { text: ''};

  render() {
    return (
      <App onShouldQuit={() => console.log('Quitting')}>
        <Window title="Test" size={{ w: 500, h: 500 }}>
            <TextInput onChange={text => this.setState({text})} multiline={true}>
              {this.state.text}
            </TextInput>
        </Window>
      </App>
    );
  }
}

I added

console.log(this, prop, this.eventParameter, translatedProp)

before the if statement here:

proton-native/src/components/DesktopComponent.js

Lines 151 to 153 in d4d9760

	const translatedProp = functionMappings[prop]; // translate React function names in libui names
	if (typeof this.eventParameter[translatedProp] === 'function') {
	// if we don't have a translatedProperty, then we use a function, so handle that

Error message:

  children:
   [ MenuBar {
       children: [Array],
       root: [Root],
       props: [Object],
       element: [UiMenu] },
     Window { children: [Array], root: [Root], props: [Object] } ],

  props:
   { onShouldQuit: [Function: onShouldQuit],
     children: [ [Object], [Object] ] },
  element: {} } 'onShouldQuit' undefined undefined

The above error occurred in the <APP> component:
    in APP (created by Notepad)
    in Notepad
