Known Subclasses:

• Thinglets.ButtonThing

Subclass this to have your object draw a hit area and detect hits. This gives your Thing the power to receive all kinds of mouse events.

This is a normal Thing, and can have other things added to it. See the help for Thing and Timeline.

Events

These events are fired. Catch them by defining a def with one of these names.

1. onDrag(x,y)
2. onDrop(dx,dy,x,y) : Use (dx,dy) to change props with. (x,y) are useful for hit testing.
3. onDown(x,y)
4. onRelease()/onClick()
5. onEnter(x,y)
6. onRollOver(x,y)
7. onLeave(x,y)

Hit Area

Define a drawHitarea method where you then draw (using paths, not stroked or filled) the hit area.

The signature is: def drawHitarea(self,context,frame_number)

Use

Typical use:

 class Touchy(HitThing):
   def __init__(self,x, y): # this is up to you
     ## Init the class - very important.
     HitThing.__init__( self, id="button" )
     self.keys( "#", Props() )
   def onRollOver(self,x,y):
     print "You are in ",x,y
   def drawHitarea(self,ctx,fr):
     ctx.rectangle(0,0,50,50) # this rectangle will be the hit-area
