bool disconnectFrameChanged(const typename QtPrivate::FunctionPointer< Func1 >::Object *receiver, Func1 slot)
Convenience function to disconnect the same style that the frame change connection was established.
void frameChanged()
Emitted when the icon changed.
QgsAnimatedIcon(const QString &iconPath=QString(), QObject *parent=nullptr)
Create a new animated icon.
int height() const
The native height of the icon.
int width() const
The native width of the icon.
bool connectFrameChanged(const typename QtPrivate::FunctionPointer< Func1 >::Object *receiver, Func1 slot)
Connect a slot that will be notified repeatedly whenever a frame changes and which should request the...

Path to a movie, e.g.
QIcon icon() const
Gets the icons representation in the current frame.
