"hitTestPoint" in "TOUCH" events, not "MOUSE" events

Platypus · April 2013

Guys,

In "button.lua" (in Gideros' included "Button" template):

the MOUSE function contains "hitTestPoint" (and "updateVisualState")

function Button:onMouseDown(event)
	if self:hitTestPoint(event.x, event.y) then
		self.focus = true
		self:updateVisualState(true)
		event:stopPropagation()
	end
end

but the TOUCH function doesn't.

function Button:onTouchesBegin(event)
	if self.focus then
		event:stopPropagation()
	end
end

Why is that?

I was going to use "onMouseDown" in my app, but maybe I should use "onTouchesBegin" instead - it seems to require less typing!

Hello @Platypus
Touch events require same hit test point as mouse events. Actually even little more typing as they have touch table:

function SomeClass:onTouchesBegin(event)
	if self:hitTestPoints(event.touch.x, event.touch.y) then
		event:stopPropagation()
	end
end

in Button class this is not required due to the fact that button already receives mouse event and touch event is only used to stop event propagation (everything underneath the button tree would not receive the event, a little optimization trick, that is not required anymore, since touch/mouse events were optimized).

@Ar2rsawseen,
Thanks, mate.
