Sigslot, a signal-slot library Sigslot is a header-only, thread safe implementation of signal-slots for C. . Reentrant safety achieved using emission copying and reference counting. Threading Policies - Aliases. When integrating nano-signal-slot, it is recommended to alias the Nano::Signal and Nano::Observer template classes. Mgm casino poker tournaments. Signals and Events in Qt. But lets start with Qt. Qt offers two different systems for our needs, Qt signal/slot and QEvents. While Qt signal/slot is the moc driven signaling system of Qt (which you can connect to via QObject::connect), there is a second Event interface informing you about certain system-like events, such as QMouseEvent, QKeyEvent or QFocusEvent. In signal-slot mechanism, the slot runs in slot’s thread even though the signal is emitted in another thread. So, signal-slot mechanism also provides inter-thread communication without a hassle.C Signal Sigusr1
I have a number of different signals connected to one slot. Is there any disconnect function that can be used to disconnect everything connected to a specific slot?
For example:C++ Signal Slot
@QObject::connect(object1, SIGNAL(a()), receiver, SLOT(slot()));
QObject::connect(object2, SIGNAL(b()), receiver, SLOT(slot()));
QObject::connect(object3, SIGNAL(c()), receiver, SLOT(slot()));@
Now I want a function to disconnect all the signals from receiver’s slot(). There is an option:
@QObject::disconnect(receiver, SLOT(slot()));@
but this connects only the signals in the current object. I want to disconnect ALL signals, without knowing the objects that are connected to the slot.
Any ideas?
