Detailed Description
The QOrbitCameraController class allows controlling the scene camera along orbital path.
The controls are:
| Input | Action | 
|---|---|
| Left mouse button | While the left mouse button is pressed, mouse movement along x-axis moves the camera left and right and movement along y-axis moves it up and down. | 
| Right mouse button | While the right mouse button is pressed, mouse movement along x-axis pans the camera around the camera view center and movement along y-axis tilts it around the camera view center. | 
| Both left and right mouse button | While both the left and the right mouse button are pressed, mouse movement along y-axis zooms the camera in and out without changing the view center. | 
| Mouse scroll wheel | Zooms the camera in and out without changing the view center. | 
| Arrow keys | Move the camera vertically and horizontally relative to camera viewport. | 
| Page up and page down keys | Move the camera forwards and backwards. | 
| Shift key | Changes the behavior of the up and down arrow keys to zoom the camera in and out without changing the view center. The other movement keys are disabled. | 
| Alt key | Changes the behovior of the arrow keys to pan and tilt the camera around the view center. Disables the page up and page down keys. | 
Property Documentation
zoomInLimit : float
Holds the current zoom-in limit. The zoom-in limit determines how close to the view center the camera can be zoomed.
Access functions:
| float | zoomInLimit() const | 
| void | setZoomInLimit(float zoomInLimit) | 
Notifier signal:
| void | zoomInLimitChanged() | 
Member Function Documentation
QOrbitCameraController::QOrbitCameraController(Qt3DCore::QNode *parent = nullptr)
Default constructs an instance of QOrbitCameraController.
[virtual] QOrbitCameraController::~QOrbitCameraController()
Destroys the instance of QOrbitCameraController. The destructor is virtual.
