Click the drag button, want to let the layer monitor hear the screen touch event, you can drag the button to start setting settouchenabled to false;
Cases:

#include "Ui/uibutton.h"

BOOL Mydemo::init () {

　　

Set Up Click events
Eventlistenertouchonebyone *listener = Eventlistenertouchonebyone::create ();
Listener->ontouchbegan = Cc_callback_2 (Mydemo::ontouchbegan, this);
listener->ontouchmoved = Cc_callback_2 (mydemo::ontouchmoved, this);
listener->ontouchended = Cc_callback_2 (mydemo::ontouchended, this);

Binding
Geteventdispatcher ()->addeventlistenerwithscenegraphpriority (listener, this);

　　

Button creation
Button *BTN = * * *;
BTN->addtoucheventlistener (Cc_callback_2 (Mydemo::btncallback, this));

This->addchild (BTN);

}

void Mydemo::btncallback (Ref *p, Cocos2d::ui::widget::toucheventtype type) {

Button *BTN = (button *) p; //

if (type = = Widget::toucheventtype::began) {

Btn->setposition (VEC2 (Btn->getpositionx ()-btn->getpositiony () + 15));
Btn->settouchenabled (FALSE);

}

}

BOOL Mydemo::ontouchbegan (Cocos2d::touch *touch, cocos2d::event *event) {

return true;

}

void Mydemo::ontouchmoved (Cocos2d::touch *touch, cocos2d::event *event) {

Cclog ("-------------------%d--------------", a++);

}

void mydemo::ontouchended (Cocos2d::touch *touch, cocos2d::event *event) {

}

When you drag a button, you enter the Ontouchmoved method
