title: Toggle Drawer from AppBar LeftIcon
body: <p>Hello Stackoverflowers,</p>
  
  <p>I'm starting my first Material-UI project with ReactJS.</p>
  
  <p>It has the AppBar and the Drawer working (Drawer only with swipe from left bezzel to right side).</p>
  
  <p>Now I want the AppBar onLeftIconButtonTouchTap to toggle the Drawer.</p>
  
  <p>This is my current code for the AppBar.jsx file:</p>
  
  <pre><code>import React from 'react';
  import AppBar from 'material-ui/AppBar';
  
  import DrawerLeft from './DrawerLeft.jsx';
  
  function handleTouchTap() {
      // Tried it her 
  }
  
  const AppBarTop = () =&gt; (
     &lt;div&gt;
          &lt;AppBar
              title="Title"
              onLeftIconButtonTouchTap={handleTouchTap}
          /&gt;
          &lt;DrawerLeft /&gt;
     &lt;/div&gt;
  );
  
  export default AppBarTop;
  </code></pre>
  
  <p>And the DrawerLeft.jsx is as follow:</p>
  
  <pre><code>import React from 'react';
  import Drawer from 'material-ui/Drawer';
  import MenuItem from 'material-ui/MenuItem';
  import RaisedButton from 'material-ui/RaisedButton';
  
  export default class DrawerLeft extends React.Component {
  
  constructor(props) {
      super(props);
      this.state = {open: false};
  }
  
  handleToggle() {
      this.setState({open: !this.state.open});
  }
  
  handleClose() {
      this.setState({open: false});
  }
  
  render() {
      return (
          &lt;div&gt;
              &lt;RaisedButton
                  label="Open Drawer"
                  onTouchTap={this.handleToggle.bind(this)}
              /&gt;
              &lt;Drawer
                  docked={false}
                  width={200}
                  open={this.state.open}
                  onRequestChange={(open) =&gt; this.setState({open})}
              &gt;
                  &lt;MenuItem onTouchTap={this.handleClose.bind(this)}&gt;Menu Item&lt;/MenuItem&gt;
                  &lt;MenuItem onTouchTap={this.handleClose.bind(this)}&gt;Menu Item 2&lt;/MenuItem&gt;
              &lt;/Drawer&gt;
          &lt;/div&gt;
      );
  }
  }
  </code></pre>
  
  <p>So how can I toggle the Drawer from the AppList its LeftIcon?</p>
  
  <p>Thanks in advance for helping me.</p>
