open external file by system application.
Message 1 in thread
I know that QProcess can open external file and communicate with it. If I
want to open a text file, I use QProcess to call up "TextEdit" (on Mac). But
if I want my program work on Windows which does not have "TextEdit", how can
I do that?
I believe there must exist something in Qt that I can use to let the system
itself decide which program need to be called to open a specific file. For
example, if I want to open a doc file (test.doc) on windows, it will call
"M$office"; when I want to open a avi file, it will call media player.
Is such thing exist in Qt? It must be I think (QUrl ? )
Thanks in advance.
Dave.

Have a look at QDesktopServices::openUrl(). Works like a charm. :)

I have to transform an xml document in pdf format and visualize it.
I use QProcess to launch xmltopdf tool and after that,
I use QDesktopServices::openUrl(generatedfile.pdf) to visualize the pdf.
system use the pdf editor installed.
