This namespace supports Piccolo event handlers. It contains event listeners for user-driven input events. It also contains basic event handlers for common typical interaction such as zooming and panning.
| Class | Description |
|---|---|
| PBasicInputEventHandler | PBasicInputEventHandler is the standard class in Piccolo that is used to register for mouse and keyboard events on a PNode. |
| PDragEventHandler | PDragEventHandler is a simple event handler for dragging a node on the canvas. |
| PDragSequenceEventHandler | PDragSequenceEventHandler is designed to support mouse pressed, dragged, and released interaction sequences. Support is also provided for running a continuous activity during the drag sequence. |
| PInputEventArgs | PInputEventArgs is used to pass keyboard and mouse event data to PInputEventListeners. |
| PPanEventHandler | PPanEventHandler provides event handlers for basic panning of the canvas view with the left mouse button. |
| PPropertyEventArgs | PPropertyEventArgs is used to pass data for a property changed event to a PPropertyEventHandler. |
| PZoomEventHandler | ZoomEventhandler provides event handlers for basic zooming of the canvas view with the right (third) button. |
| Interface | Description |
|---|---|
| PInputEventListener | PInputEventListener defines an interface for objects that want to listen to PNodes for input events. If you are just using Piccolo's default input management system then you will most often use PBasicInputEventHandler to register with a node for input events. |
