◆ event()

bool QQuickWorkerScriptEnginePrivate::event ( QEvent *  e)
overrideprotectedvirtual

This virtual function receives events to an object and should return true if the event e was recognized and processed.

The event() function can be reimplemented to customize the behavior of an object.

Make sure you call the parent event class implementation for all the events you did not handle.

Example:

class MyClass : public QWidget
{
Q_OBJECT
public:
MyClass(QWidget *parent = nullptr);
~MyClass();
bool event(QEvent* ev) override
{
if (ev->type() == QEvent::PolishRequest) {
// overwrite handling of PolishRequest if any
doThings();
return true;
} else if (ev->type() == QEvent::Show) {
// complement handling of Show if any
doThings2();
QWidget::event(ev);
return true;
}
// Make sure the rest of events are handled
return QWidget::event(ev);
}
};
