[Qt-interest] How to get an icon associated with a certain filetype using Qt?

[André Somers]

Ah, sorry, I missed that. In that case, the issue is rather more challenging
indeed... It would be nice if the interface would be extended with an option
to query based on mimetype, but that does not help you now. I am afraid
you'll need to resort to platform dependent code, just like Qt itself does.
Perhaps studying the sources of QFileIconProvider will help you get what you
want. I just looked, and at least for windows it seems to use the file
extension. Do you happen to have the file name too?

Yes, this is what I was referring to ... the IconType enumeration.

As indicated in my previous messages, I have no file ... all I have at 
the point where I need the icon is the MIME type as given in the email 
"Content-Type" header. There is no way of knowing in advance whether or 
not this file has an associated icon until I decode the base64 (usually 
it is in this format) and save it as an actual file on the user's 
machine. I'd rather not have to do that unless the user wanted to save it.
