How do I add event listeners to the <Output> element in XtermAdapter?

 render() {
  // Use state and refs in your render method
  return (
   <>
    <Output
     elements={this.state.outputElements}
    />
    <NextCharsDisplay
     ref={this.nextCharsDisplayRef}
     onTimerStatusChange={this.handleTimerStatusChange}
     onNewPhraseSet={this.handleNewPhraseSet}
     commandLine={this.state.commandLine}
     isInPhraseMode={this.state.isInPhraseMode}
    />
    <div
     ref={this.terminalElementRef as React.RefObject<HTMLDivElement>}
     id={TerminalCssClasses.Terminal}
     className={TerminalCssClasses.Terminal}
    />
    <video
     id="terminal-video"
     hidden={!this.isShowVideo}
    ></video>
   </>
  );
 }

To add event listeners to the <Output> element in your XtermAdapter, you should define the event listeners in the Output component itself. Since React encourages the use of props to handle events, you could pass down event handling functions as props from the XtermAdapter to the Output component.

First, define the event listeners in your XtermAdapter component:

handleOutputClick(event) {
  console.log('Output clicked', event);
}

handleOutputMouseOver(event) {
  console.log('Output mouse over', event);
}

Then, pass these functions as props to the Output component:

<Output
  elements={this.state.outputElements}
  onClick={this.handleOutputClick}
  onMouseOver={this.handleOutputMouseOver}
/>

Now, in your Output component, you should add these event listeners to the root element or to specific children elements, depending on your requirements. For example, if Output is a functional component, you would add the event listeners like this:

const Output = ({ elements, onClick, onMouseOver }) => {
  return (
    <div onClick={onClick} onMouseOver={onMouseOver}>
      {/* Render elements here */}
    </div>
  );
};

Make sure the Output component is set up to accept and use these new props. If the Output component is a class component, you would add the event listeners in a similar way, but you would access the props with this.props.

Remember that if you are using TypeScript, you should also update the type definitions for the Output component props to include the new event handling functions.
