QMetaObjectCleanUp is part of the Qt library in C++. This class is used to register an object to be cleaned up after the application has exited. The QMetaObjectCleanUp class is particularly useful when working with dynamically created objects that need to be cleaned up at the end of the program.
This is an example of registering an object for clean-up:
QMetaObjectCleanUp::registerWidget(widget);
In this example, the widget object is registered for clean-up. When the program exits, the QMetaObjectCleanup cleanup function will be called to destroy the widget.
This code example shows how to use QMetaObjectCleanUp to clean-up a dynamically created object:
QLabel* myLabel = new QLabel("My Label", parent); QMetaObjectCleanUp::registerWidget(myLabel);
In this example, a QLabel object is created dynamically and registered for clean-up using QMetaObjectCleanUp. When the parent object is destroyed, the QLabel object will be destroyed as well.
Overall, the QMetaObjectCleanUp class is a convenient way to ensure that objects are cleaned up properly, particularly when working with dynamically created objects. It is part of the QtCore library in the Qt framework.
