## Signals

void | inversePanChanged(bool isInverse)
void | inverseTiltChanged(bool isInverse)
void | inverseXTranslateChanged(bool isInverse)
void | inverseYTranslateChanged(bool isInverse)
void | upVectorChanged(const QVector3D &upVector)
void | zoomInLimitChanged()
void | zoomTranslateViewCenterChanged(bool isTranslate)

## Detailed Description

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.
Escape | Moves the camera so that entire scene is visible in the camera viewport.

## 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()
