Compiling it sucks (less now), running it typically doesn't. The beauty of moc is that it front loads a lot of the magic. It could be that the signal coming from the CMP is not. one signal, all unrelated code in one slot (in my case, changing color + validation) one signal, multiple slots Put my problem aside, which is better design Another option is. If a signal is connected to several slots, the slots are activated in the same order as the order the connection was. qt of oil (oil consumption issue) called the dealer they said no recalls on the. WhatIf said: I will check QValidator but which is the better approach. Having dabbled with Qt off and on for decades I wasn't surprised. Many signals can be connected to one slot. You're surprised signals are fairly low overhead (and that's fine) and and wondered if anyone actually thought they were performant. I wonder who thought signals were fast to begin with? Insofar as other overhead sensitive environments go, Trolltech ported Qt (including the signal/slot paradigm) to a realtime OS (QNX) and features it prominently in safety critical contexts (e.g. It's actually pretty difficult to structure something such that a signals/slots become a performance bottleneck. That's what Trolltech recommended and almost certainly what the current crop of ioslaves do today (okay I lied, it looks like there are dedicated socket classes that provide their own signals these days). What context am I missing? You're talking about network I/O as being a bad use case for signals/slots and I've pointed out that I (along with other KDE folks) wrote code using signals/slots to handle incoming network data.
