Detailed Description
Note: QMouseHandler components shouldn't be shared, not respecting that condition will most likely result in undefined behaviors.

Property Documentation
containsMouse : const bool
Holds true if the QMouseHandler currently contains the mouse.
Note: In this context, contains mean that the ray originating from the mouse is intersecting with the Qt3DCore::QEntity that aggregates the current QMouseHandler instance component.
Access functions:
| bool | containsMouse() const |
Notifier signal:
| void | containsMouseChanged(bool containsMouse) |
sourceDevice : Qt3DInput::QMouseDevice*
Holds the current mouse source device of the QMouseHandler instance.
Access functions:
| QMouseDevice * | sourceDevice() const |
| void | setSourceDevice(QMouseDevice *mouseDevice) |
Notifier signal:
| void | sourceDeviceChanged(QMouseDevice *mouseDevice) |
Member Function Documentation
QMouseHandler::QMouseHandler(QNode *parent = nullptr)
Constructs a new QMouseHandler instance with parent parent.
[signal] void QMouseHandler::clicked(Qt3DInput::QMouseEvent *mouse)
This signal is emitted when a mouse button is clicked with the event details being contained within mouse.
[signal] void QMouseHandler::doubleClicked(Qt3DInput::QMouseEvent *mouse)
This signal is emitted when a mouse button is double clicked with the event details being contained within mouse.
[signal] void QMouseHandler::entered()
[signal] void QMouseHandler::exited()
[signal] void QMouseHandler::positionChanged(Qt3DInput::QMouseEvent *mouse)
This signal is emitted when the mouse position changes with the event details being contained within mouse
[signal] void QMouseHandler::pressAndHold(Qt3DInput::QMouseEvent *mouse)
This signal is emitted when a mouse button is pressed and held down with the event details being contained within mouse
[signal] void QMouseHandler::pressed(Qt3DInput::QMouseEvent *mouse)
This signal is emitted when a mouse button is pressed with the event details being contained within mouse
[signal] void QMouseHandler::released(Qt3DInput::QMouseEvent *mouse)
This signal is emitted when a mouse button is released with the event details being contained within mouse
[slot] void QMouseHandler::setSourceDevice(QMouseDevice *mouseDevice)
Sets the mouse device of the QMouseHandler instance to mouseDevice.
Note: Setter function for property sourceDevice.
See also sourceDevice().
[signal] void QMouseHandler::wheel(Qt3DInput::QWheelEvent *wheel)
This signal is emitted when the mouse wheel is used with the event details being contained within wheel
