How to get default email client to open on clicking 'email' button

[wysota]

It means the process didn't start but reasons for that may vary. Check what getenv("BROWSER") returns, maybe it is not set on a particular system.

You can open any site you want by providing a different address than mailto:something (like http://www.yourmailsiteaddress.com). But this will only work if the default browser is set (using the $BROWSER env variable).

Hi,
used a QMessageBox to get the value of getenv.It shows a blank.
Any suggestions on what else I could try?
Also,thanks for being patient and replying to my queries.

What happens if you write env|grep BROWSER in a terminal?

If BROWSER is empty then you need to ask the user to set his email client in the preferences of the application.
