com.db.behaviors.PickViewerBehavior
All known Subclasses: com.db.behaviors.StandardPickViewer,
| PickViewerBehavior | | abstract public class PickViewerBehavior extends Behavior (Code) | | A mouse behavior that allows user to pick and minipulate scene graph objects.
Manipulations include translation, rotation and zoom.
The behavior maps mouse drags to different transforms depending
upon the mosue button held down:
Button 1 (left)
Translation of dragged object
Button 2 (middle)
Rotation of dragged object around itself
Button 3 (right)
Zoom of dragged object towards user
To support systems with 2 or 1 mouse buttons, the following
alternate mappings are supported while dragging with any mouse
button held down and zero or more keyboard modifiers held down:
No modifiers = Button 1
ALT = Button 2
Meta = Button 3
Control = Button 3
Common usage:
1. Create your scene graph.
2. Create this behavior with root and canvas.
StandardPickViewerBehavior behavior = new StandardPickViewerBehavior(canvas, root, bounds);
root.addChild(behavior);
The above behavior will monitor for any picking events on
the scene graph (below root node) and handle mouse drags on pick hits.
Note the root node can also be a subgraph node of the scene graph (rather
than the topmost).
