|
|
* ControlP5 extending Controllers
|
|
*
|
|
* the following example shows how to extend the Controller class to
|
|
* create customizable Controllers. You can either extend the Controller class itself,
|
|
* or any class that extends Controller itself like the Slider, Button, DropdownList, etc.
|
|
*
|
|
* How to:
|
|
*
|
|
* 1) do a super call to the convenience constructor requiring
|
|
* 2 parameter (ControlP5 instance, name)
|
|
*
|
|
* 2) the Controller class has a set of empty methods that allow you to capture
|
|
* inputs from the mouse including
|
|
* onEnter(), onLeave(), onPress(), onRelease(), onClick(), onScroll(int), onDrag()
|
|
* These you can override and include functionality as needed.
|
|
*
|
|
* 3) use method getPointer() to return the local (relative)
|
|
* xy-coordinates of the controller
|
|
*
|
|
* 4) after instantiation custom controllers are treated the same
|
|
* as default controlP5 controllers.
