title: Masking a plugin (or applet) to show html content over it in Chrome on the Mac
body: <p>For all other browsers that I've tried in both Windows and MacOSX (including Chrome under Windows) using an "iframe shim" works fine. However, I have not been able to get iframe shims to work over our plugin in Chrome on the Mac.</p>
  
  <p>Having Googled the problem, and done some testing, it appears to depend upon the object. I've found an example using StreetView (a flash object) which works, and another example using a Java Applet which does not work.</p>
  
  <p>Some links:</p>
  
  <p>Here's a description of the method: <a href="http://www.oratransplant.nl/2007/10/26/using-iframe-shim-to-partly-cover-a-java-applet/" rel="nofollow">http://www.oratransplant.nl/2007/10/26/using-iframe-shim-to-partly-cover-a-java-applet/</a></p>
  
  <p>This example using a Java Applet is from the above article: <a href="http://www.oratransplant.nl/files/iframe_shim.html" rel="nofollow">http://www.oratransplant.nl/files/iframe_shim.html</a></p>
  
  <p>And here's the working version using Streetview: <a href="http://gmaps-samples.googlecode.com/svn/trunk/streetview/iframeshim.html" rel="nofollow">http://gmaps-samples.googlecode.com/svn/trunk/streetview/iframeshim.html</a></p>
  
  <p>By inspecting (and editing) elements in Chrome and copying the objects between the two example pages, it appears to be that the flash object just allows iframe shims (in Chrome on the Mac), but that the Java Applet does not.</p>
  
  <p>In our case we are using a custom plugin, built with Firebreath.</p>
  
  <p>It may be that I need to implement extra functionality into our plugin, mimicking whatever flash is doing, but this could well be caused by a bug in the Mac build of Chrome.</p>
  
  <p>Can anyone help? We really do want to be able to show HTML elements over our plugin, and the iframe shim works on almost all browser/OS combinations!</p>
