How to display an existing pdf file

Group
What would be the quickest way to display an existing pdf file like /tmp/somepdf.pdf i was thinking a QWebView? Afterwards i worry
about printing it. Thanks for any help.

Use the Poppler library.

for start with poppler you can see the source code of TeXworks or Texmaker, both are opensource Qt projects and both have an embedded PDF viewer.
