Qt: wait for a signal in synchronously mode Qt libraries work using the mechanism called signal-slot. Basically this is a optimal way to make an asynchronous communication between objects in any kind of conditions and transmitting any kind of data. However, sometimes, may happen the need to wait for a very short time event (for example wait for the end of a short animation). Qt 5 and C++11: Lambdas Are Your Friend | Custom Software ... I believe the signal/slot mechanism has found its soul mate in C++11 lambda functions. What’s this signal/slot thingy? If you don’t work in Qt you probably don’t care anyway but the fundamental communication mechanism between objects in the Qt framework is defined by signals (events that can be emitted) and slots (handlers for events).

multi-tier architecture: how to have out-of-process signal-slot? For sure it is an important part of a multi tier distributed application, but I would like to focus on an easy way for exchanging signals and slots between processes. I continued googling to find something and I found something. I found something that was available in the early days of Qt (at least before Qt 5): QtopiaIpcAdaptor. PySide/PyQt Tutorial: Creating Your Own Signals and Slots ... Now, let's define some slots that can be connected to the Circle's signals. Remember last time, when we said we'd see more about the @Slot decorator? We now have signals that carry data, so we'll see how to make slots that can receive it. To make a slot accept data from a signal, we simply define it with the same signature as its signal: PySide ... SignalsandSlots in C++ - sigslot - C++ Signal/Slot Library SignalsandSlots in C++ SarahThompson∗ March2002 1 Introduction This paper introduces the sigslot library, which implements a type-safe, thread-safe signal/slot mech-anism in C++. The library is implemented entirely in C++, and does not require source code to be pre-processed1 in order for itto be used.
