| enum | Result { File , Directory , Fallback , Unknown } |
Signals | |
| void | request (const QString &file) |
| Signals inherited from QObject | |
| void | destroyed (QObject *=nullptr) |
| This signal is emitted immediately before the object obj is destroyed, after any instances of QPointer have been notified, and cannot be blocked. | |
| void | objectNameChanged (const QString &objectName, QPrivateSignal) |
| This signal is emitted after the object's name has been changed. | |
Public Member Functions | |

| void | whitelist (const QUrl &url) |
| bool | isBlacklisted (const QString &file) |
| Public Member Functions inherited from QObject | |
| Q_INVOKABLE | QObject (QObject *parent=nullptr) |
| Constructs an object with parent object parent. | |
| virtual | ~QObject () |
| Destroys the object, deleting all its child objects. | |
| virtual bool | event (QEvent *event) |
| This virtual function receives events to an object and should return true if the event e was recognized and processed. | |
| virtual bool | eventFilter (QObject *watched, QEvent *event) |
| Filters events if this object has been installed as an event filter for the watched object. | |
| QString | objectName () const |
| Q_WEAK_OVERLOAD void | setObjectName (const QString &name) |
| Sets the object's name to name. | |
| void | setObjectName (QAnyStringView name) |
| This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. | |

Returns true if the object is a QQuickItem; otherwise returns false. | |
| bool | signalsBlocked () const noexcept |
Returns true if signals are blocked; otherwise returns false. | |
| bool | blockSignals (bool b) noexcept |
| If block is true, signals emitted by this object are blocked (i.e., emitting a signal will not invoke anything connected to it). | |
| QThread * | thread () const |
| Returns the thread in which the object lives. | |
| void | moveToThread (QThread *thread) |
| Changes the thread affinity for this object and its children. | |
| int | startTimer (int interval, Qt::TimerType timerType=Qt::CoarseTimer) |
| This is an overloaded function that will start a timer of type timerType and a timeout of interval milliseconds. | |
| int | startTimer (std::chrono::milliseconds time, Qt::TimerType timerType=Qt::CoarseTimer) |
| void | killTimer (int id) |
| Kills the timer with timer identifier, id. | |
| template<typename T > | |
| T | findChild (const QString &aName=QString(), Qt::FindChildOptions options=Qt::FindChildrenRecursively) const |
| Returns the child of this object that can be cast into type T and that is called name, or \nullptr if there is no such object. | |
| template<typename T > | |
| QList< T > | findChildren (const QString &aName, Qt::FindChildOptions options=Qt::FindChildrenRecursively) const |
| Returns all children of this object with the given name that can be cast to type T, or an empty list if there are no such objects. | |
| template<typename T > | |
| QList< T > | findChildren (Qt::FindChildOptions options=Qt::FindChildrenRecursively) const |
| This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. | |
| const QObjectList & | children () const |
| Returns a list of child objects. | |
| void | setParent (QObject *parent) |
| Makes the object a child of parent. | |
| void | installEventFilter (QObject *filterObj) |
| Installs an event filter filterObj on this object. | |
| void | removeEventFilter (QObject *obj) |
| Removes an event filter object obj from this object. | |

| bool | disconnect (const char *signal=nullptr, const QObject *receiver=nullptr, const char *member=nullptr) const |
| bool | disconnect (const QObject *receiver, const char *member=nullptr) const |
| void | dumpObjectTree () const |
| Dumps a tree of children to the debug output. | |
| void | dumpObjectInfo () const |
| Dumps information about signal connections, etc. | |
| bool | setProperty (const char *name, const QVariant &value) |
| Sets the value of the object's name property to value. | |
| bool | setProperty (const char *name, QVariant &&value) |
| QVariant | property (const char *name) const |
| Returns the value of the object's name property. | |
| QList< QByteArray > | dynamicPropertyNames () const |
| QBindingStorage * | bindingStorage () |
| const QBindingStorage * | bindingStorage () const |
| QObject * | parent () const |
| Returns a pointer to the parent object. | |
| bool | inherits (const char *classname) const |
Returns true if this object is an instance of a class that inherits className or a QObject subclass that inherits className; otherwise returns false. | |
