Hi, just want to thank whoever worked to implement qScopeGuard (in
5.12), it was a perfect gift from heaven today :-)
I'm writing a LOB app with heavy database munging, and want to show the
user an hourglass cursor while munging/waiting for MS SQLServer.
However my functions have lots of exits due to bad weather etc. and I
dreaded pasting a restore-mouse-cursor call everywhere. Googled a bit
and now I use this 2-line magic at the top of my functions:
...
qApp->setOverrideCursor(Qt::WaitCursor);
auto restoreCursor = qScopeGuard([] {
qApp->restoreOverrideCursor(); });
...
Before I discovered Qt I spent 20 years in MFC purgatory, but now I've
seen the light!
