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() |
