Changeset 6 for trunk/src/Document.cxx

Timestamp:

Author:

Message:

The Document class now actually tries to open a PDFDoc document from Poppler and reports an error if it can't find the PDF file.

Also, now the test file has a member which is the document to test, since it will be the same for all test (even for the empty, because I don't load a file in the setUp() function).
