Thanks for your reply.
Sorry about that extra "", was left over from my file type check. There is
probably a better way to do it but this was the first thing I thought of:
if (path!="") {
QStringList arguments;
QString foo = "/usr/bin/file "+path+" | grep JPEG";
arguments << "-c" << foo;
QProcess* process = new QProcess(this);
process->start("/bin/sh", arguments);
process->waitForFinished();
QString tmp = process->readAll();
qDebug() << "results:" << tmp;
if (tmp.lastIndexOf("JPEG")>0) {
I added "results:" to make sure that was actually spitting out the ""
example:
path:
"/home/waitman/pv2012/2012-06-15/marina/DCIM/100CANON/jpeg-out/IMG_5643.ppm.jpg"
results:
"/home/waitman/pv2012/2012-06-15/marina/DCIM/100CANON/jpeg-out/IMG_5643.ppm.jpg:
JPEG image data, JFIF standard 1.01
"
path: "/home/waitman/pv2012/2012-06-15/marina/DCIM/100CANON/ppm/IMG_5877.ppm"
results: ""
The program has unexpectedly finished.
/usr/home/waitman/puf/puf exited with code 0
When I switch to lastIndexOf("JPEG")<0 ... (not a JPEG) and load a PPM it halts.
** What's strange to me is it mysteriously worked one time just a few minutes
ago....

.. etc
no problems
but when i restart, it crashes again. restarting multiple times, cleaning and
rebuild it's still halting. i checked the images that were loading, it still
halts.
(note the first click is on the directory path, does not cause stop)

results: ""
The program has unexpectedly finished.
/usr/home/waitman/puf/puf exited with code 0
moving my qDebug() << "here" line around i found that it stops here:
statusBar()->showMessage(
tr("puf (%1) ")
.arg(pm.width()+","+pm.height()));
maybe that's not correct, checking it out. it seems to work with JPEG without
any issues, and i did actually see it run one time (randomly).
Thanks,
