How to disable pop-out option in pdf viewer with google doc iframe?

Question

I am using following code to display pdf using google with iframe.. It's working fine. But I want to disable "pop-out" option (which on click opening my pdf in new tab with google docs) shown on right upper corner beside zoomin option on my webpage. Is it possible?

Currently I am using following code -

<iframe src="http://docs.google.com/gview?url=http://example.com/files/myfile.pdf&embedded=true" style="width:600px; height:500px;" frameborder="0">

Solution

Can use sandbox to stop the popup working inside iframe

<iframe 
    sandbox="allow-scripts allow-same-origin"
/>

allow-scripts: to run javascript inside iframe.
allow-same-origin: to allow loading file from google viewer.
without allow-popups, nothing will happen when users click on pop-out icon.
