Looks like it wasn't connecting to my flickrviewsengine because the isvalid variable was false. So I changed things up a bit. Decided to use the Time engine because that's the one always used in examples. Still got the same error.

So I figure I need to solve the problem with the known working time engine before I tackle what's wrong with mine. (I think it's because I added the engine as root - it doesn't so up in my user's engine explorer - only in root's) -- Eric Mesa http://www.ericsbinaryworld.com --e89a8ffba0c37a4c6804b7271760 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Ran things through the QT Creator debugger. =A0Looks like it wasn't con= necting to my flickrviewsengine because the isvalid variable was false. =A0= So I changed things up a bit. =A0Decided to use the Time engine because tha= t's the one always used in examples. =A0Still got the same error. =A0He= re's my current code:

So I figure I need to solve the problem with the known working time engine= before I tackle what's wrong with mine. =A0(I think it's because I= added the engine as root - it doesn't so up in my user's engine ex= plorer - only in root's)
