Implementing Press-and-hold event ?

[smilesnigam]

hello everyone,

can someone please help me with implementing press-and-hold key event? I want to hold a key for sometime to trigger a new function.
i am using the class used in default.py to handle keyboard events.

thanks

I tried to catch the number of repeating keys to implement press and hold event,but i think there is some error in the code.

class Keyboard(object):
    def __init__(self,onevent=lambda:None):
        self._keyboard_state={}
        self._downs={}
	self._onevent=onevent	
		
    def press_hold(self,scancode):
	repeat=0
	print repeat
	while self.pressed(scancode):
		if repeat==10:
			 return True
		print repeat 
		repeat=repeat+1

    def handle_event(self,event):    
	if event['type'] == appuifw.EEventKeyDown:
            code1=event['scancode']
            if not self.is_down(code1):
                self._downs[code1]=self._downs.get(code1,0)+1
            self._keyboard_state[code1]=1
        elif event['type'] == appuifw.EEventKeyUp:
            self._keyboard_state[event['scancode']]=0
        self._onevent()
    def is_down(self,scancode):
        return self._keyboard_state.get(scancode,0)
    def pressed(self,scancode):
        if self._downs.get(scancode,0):
            self._downs[scancode]-=1
            return True
        return False

Can someone look at it and tell me where am i making a mistake.
