The same is true whenever you do a system call in a slot; or indirectly call more than ten functions. On an i586-500, you can emit around 2,000,000 signals per second connected to one receiver, or around 1,200,000 per second connected to two receivers. The simplicity and flexibility ...
The signals and slots mechanism is type safe: The signature of a signal must match the signature of the receiving slot. (In fact a slot may have a shorter signature than the signal it receives because it can ignore extra arguments.) Since the signatures are compatible, the compiler can help...
While the signals can be declared in the interface class, their definition is auto-generated by Qt'smocduring the compilation process. Thus I can define these signals in the interface class, but when creating a plugin which implements the interface, the build fails at link. T...

Normalize the arguments for signals + slots (see QMetaObject::normalizedSignature) inside connect statements to get faster signal/slot lookups. You can use qtrepotools/util/normalize to normalize existing code. Including headers In public header files, always use this form to include Qt headers: ...
