[solved]How to catch error when printing QTextDocument to pdf when pdf is open?

[qmlLearner]

Hi!
I am printing a QTextDocument to a pdf with the following command:
@doc.print(&printer);@

It runs fine except when the pdf is already opened in a viewer (e.g. foxit reader), which makes sense as the printer doesn't have write permissions probably. Unfortunately, I haven't figured out how to catch this error, as the .print function is void. The only thing I see is the following on the console:
@QPainter::begin(): Returned false@

How can I catch this?
Thank you for any help!

Hi,

Maybe using QDir to list writable files before printing might work

Hope it helps

Thank you for you hint!
The way I do it now is to try to open the file in write mode. If it is successful, I can continue with to printing, otherwise I throw an error.
Thank you again for pointing me into this direction!
