QMetaObject::Connection, connect(const QObject *sender, const char *signal, const QObject *receiver, const char *method, Qt::ConnectionType type Public Functions · Static Public Members · Macros · Detailed Description. In GUI programming, when we change one widget, we often want another widget to be notified. Thread Affinity A QObject instance is said to have a thread affinity , or that it lives in a certain thread. The reasoning is found in the discussion on Identity vs Value on the Qt Object Model page. UniqueConnection type , the connection will only be made if it is not a duplicate. The QObject class is the base class of all Qt objects. We use signals and slots.

Changing the value of a dynamic property causes a QDynamicPropertyChangeEvent to be sent to the object. If there is already a duplicate exact same signal to the exact same slot on the same objects , the connection will fail and connect will return false. If any of these objects are on the stack or global, sooner or later your program will crash. The convenience function isWidgetType returns whether an object is actually a widget. ChildPolished events are sent to widgets when children are polished, or when polished children are added. If either filterObj or this object are moved to a different thread after calling this function, the event filter will not be called until both objects have the same thread affinity again it is not removed. Suppose you have three push buttons that determine which file you will open: QTimer provides a higher-level interface to the timer functionality, and also more general information about timers.

A slot is a function that is paper mario world in response to a particular signal. When a signal is emitted, the slots connected to it are usually executed immediately, just like a normal function. If there is already a duplicate exact same signal to the exact same slot on the same objectsthe connection will fail and connect will return false. See also signalsBlocked and QSignalBlocker. When you create a QObject with another object as parent, the object will automatically add itself to the parent's children list. Omitting the name argument causes all object names to be matched.
