(!) Note
This is a fork of https://github.com/bpmn-io/bpmn-js-example-react-properties-panel with latest version of react, bpmn-js, and app functional component
React Properties Panel for bpmn-js
This example demonstrates a custom properties panel for bpmn-js written in React.
About
The component PropertiesView implements the properties panel.
The component is mounted via standard React utilities and receives the BPMN modeler instance as props:
<PropertiesView modeler={ modeler } />As part of its life-cycle hooks it hooks up with bpmn-js change and selection events to react to editor changes:
class PropertiesView extends React.Component {
...
componentDidMount() {
const {
modeler
} = this.props;
modeler.on('selection.changed', (e) => {
this.setElement(e.newSelection[0]);
});
modeler.on('element.changed', (e) => {
this.setElement(e.element);
});
}
}Rendering the component we may display element properties and apply changes:
class PropertiesView extends React.Component {
...
render() {
const {
element
} = this.state;
return (
<div>
<fieldset>
<label>id</label>
<span>{ element.id }</span>
</fieldset>
<fieldset>
<label>name</label>
<input value={ element.businessObject.name || '' } onChange={ (event) => {
this.updateName(event.target.value);
} } />
</fieldset>
</div>
);
}
updateName(newName) {
const {
element
} = this.state;
const {
modeler
} = this.props;
const modeling = modeler.get('modeling');
modeling.updateLabel(element, newName);
}
