change cursor icon while program is busy

[Tomasz]

So I have no idea why my app is crashing if I try to delete my QProcess object:

connect(proc, SIGNAL(finished(int)), this, SLOT(appIsLoaded()));
connect(proc, SIGNAL(finished(int)), this, SLOT(deleteLater()));  //without it works fine, no errors
proc->start("/myapp", QStringList() << parameter);

connect(proc, SIGNAL(finished(int)), this, SLOT(appIsLoaded()));
connect(proc, SIGNAL(finished(int)), this, SLOT(deleteLater()));  //without it works fine, no errors
proc->start("/myapp", QStringList() << parameter);

To copy to clipboard, switch view to plain text mode 

It happens when I run process by start() If I use startDetached() I can delete QProcess object without any error... I've checked if I'm deleting something twice, and I'm not. QProcess object is the only thing I'm deleting.

thanks in advance
best regards
