Button unable to enable or Disable Events ...

DoradoLab

Hi Team,

I am having a image button and once after click it i need to make it disable ( Events should not trigger even if the Events not removed). Can you tell me how can i use it... I referred this below code but it didnt work for me. Please give me specific code.

wpPiece3.enabled = true -- to make it click

-- OR --

wpPiece3.enabled = false -- to make it not click



Thanks

Just an idea,
-Make a state variable for your button called enabled, in your button class. If you are not using a class for button maybe just a global variable do the trick.
Let's name it;
enabled=true
-By default it will be enabled then when pressed one time on event of onpress just make an if clause like,
if enabled then
--write your code here
enabled=false
end
-Whenever you want to activate it just change the enabled variable to enabled=true and your events will work again.

But if you are asking my opinion removing the listener will be much more easy:D

yes exactly as @talis said, removing listeners is the easy way, so if you use the standard Button lua class from here:
https://github.com/gideros/Button/blob/master/button.lua
you can modify it by adding two methods:

function Button:enable() if self.disabled then self.disabled = false -- register to all mouse and touch events self:addEventListener(Event.MOUSE_DOWN, self.onMouseDown, self) self:addEventListener(Event.MOUSE_MOVE, self.onMouseMove, self) self:addEventListener(Event.MOUSE_UP, self.onMouseUp, self)   self:addEventListener(Event.TOUCHES_BEGIN, self.onTouchesBegin, self) self:addEventListener(Event.TOUCHES_MOVE, self.onTouchesMove, self) self:addEventListener(Event.TOUCHES_END, self.onTouchesEnd, self) self:addEventListener(Event.TOUCHES_CANCEL, self.onTouchesCancel, self) end end   function Button:disable() if not self.disabled then self.disabled = true -- register to all mouse and touch events self:removeEventListener(Event.MOUSE_DOWN, self.onMouseDown, self) self:removeEventListener(Event.MOUSE_MOVE, self.onMouseMove, self) self:removeEventListener(Event.MOUSE_UP, self.onMouseUp, self)   self:removeEventListener(Event.TOUCHES_BEGIN, self.onTouchesBegin, self) self:removeEventListener(Event.TOUCHES_MOVE, self.onTouchesMove, self) self:removeEventListener(Event.TOUCHES_END, self.onTouchesEnd, self) self:removeEventListener(Event.TOUCHES_CANCEL, self.onTouchesCancel, self) end end
