[Solved] single signal to multiple slots | Qt Forum hello, How many slots can you connect to a signal? Signals & Slots | Qt 4.8 Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, ...
I'm wondering if it possible to connect multiple clients within a single session. Which means : I'm trying to display a desktop at four different places with four diffrent computers.Qt uses signals and slots normally in a single thread, so calling a signal will call a slot in the same thread signal called.

How Qt Signals and Slots Work - Woboq The connection mechanism uses a vector indexed by signals. But all the slots waste space in the vector and there are usually more slots than signals in an object. So from Qt 4.6, a new internal signal index which only includes the signal index is used. While developing with Qt, you only need to know about the absolute method index. How Qt Signals and Slots Work - Part 3 - Queued and Inter ...

Connecting two signals - Qt 5 Blueprints Basically, connecting two signals is a simplified version of connecting a signal and a slot, while the slot is meant to emit another signal. As for priority, the slot(s) of the latter signal will be handled when the event loop is returned to the object. However, it is impossible to connect two slots because the mechanism requires a signal while Signals and Slots | Introduction to GUI Programming with
