Why Click event does not respond

cocos2d-x C++
#1 
auto bb = cocos2d::ui::ImageView::create("xxx.png", Widget::TextureResType::LOCAL);
	bb->setPosition(VisibleRect::center());
	bb->addTouchEventListener(CC_CALLBACK_2(HelloWorld::touchEvent, this));
	this->addChild(bb);

void HelloWorld::touchEvent(Ref *pSender, Widget::TouchEventType type)
{
	switch (type)
	{
	case Widget::TouchEventType::BEGAN:
		break;
	case Widget::TouchEventType::MOVED:
		break;
	case Widget::TouchEventType::ENDED:
	{
	}
	break;
	case Widget::TouchEventType::CANCELED:
		break;
	default:
		break;
	}
}

When I click the button, The event does not respond.
In HelloWorldScene demo with 3.17.1 cocos2d-x C++.

The example in cpp-tests works for me:

 ImageView* imageView = ImageView::create("cocosui/ccicon.png");


 imageView->setTouchEnabled(true);
 imageView->addTouchEventListener([=](Ref* sender, Widget::TouchEventType type){
            if (type == Widget::TouchEventType::ENDED) {
                if (imageView->isScale9Enabled())
                {
                    // code
                }
                else
                   // code
            }
        });

Oh ! thanks man.

I create a layer in hello world scene then add imageview in layer, I found that the click event not response.

#5

show more code?

#6 
auto layer = EightBallLayer::create();
this->addChild(layer);

#include "EightBallLayer.h"

USING_NS_CC;
using namespace cocos2d::ui;

EightBallLayer::EightBallLayer()
{

}

EightBallLayer::~EightBallLayer()
{

}

bool EightBallLayer::init()
{
//BilliardBaseLayer::initView();

auto bb = ImageView::create("gameBilliards/eightBall/eightBall_SliderBar_Power.png", Widget::TextureResType::LOCAL);
bb->setTouchEnabled(true);
bb->setPosition(VisibleRect::center());
bb->addTouchEventListener(CC_CALLBACK_2(EightBallLayer::touchEvent, this));
this->addChild(bb);

return true;

}

void EightBallLayer::touchEvent(cocos2d::Ref pSender, Widget::TouchEventType type)
{
Node sender = dynamic_cast<Node*>(pSender);
if (sender == nullptr)
return;
int tag = sender->getTag();
switch (type)
{
case Widget::TouchEventType::BEGAN:
sender->setScale(1.05f);
break;
case Widget::TouchEventType::MOVED:

	break;
case Widget::TouchEventType::ENDED:
	sender->setScale(1.0f);
	AudioMgr::getInstance()->playClickEffect();
	break;
case Widget::TouchEventType::CANCELED:
	sender->setScale(1.0f);
	break;
default:
	break;
}

}

void EightBallLayer::onEnter()
{

}

void EightBallLayer::onExit()
{

}

#ifndef __EIGHTBALLLAYER_H__

#define EIGHTBALLLAYER_H

#include “…/common/VisibleRect.h”

#include “cocos2d.h”
#include “cocostudio/CocoStudio.h”

class EightBallLayer : public cocos2d::Layer
{
public:

~EightBallLayer();

CREATE_FUNC(EightBallLayer);

virtual void onExit() override;

cocos2d::Node* _node;
};

#endif

#7

Its pretty hard to make sense of this can you format it a bit better please. You can use markdown syntax and code blocks

#8

It’s layer head:

=============================================================================

#ifndef EIGHTBALLLAYER_H
#define EIGHTBALLLAYER_H
#include “…/common/VisibleRect.h”
#include “cocos2d.h”
#include “cocostudio/CocoStudio.h”
#include “ui\UIImageView.h”
class EightBallLayer : public cocos2d::Layer
{
public:
EightBallLayer();
~EightBallLayer();
virtual bool init() override;
void touchEvent(cocos2d::Ref* sender, cocos2d::ui::Widget::TouchEventType type);
CREATE_FUNC(EightBallLayer);
virtual void onEnter() override;
virtual void onExit() override;
private:
cocos2d::Node* _node;
};
#endif

=============================================================================

It's cpp file.

=============================================================================

#include “EightBallLayer.h”
USING_NS_CC;
using namespace cocos2d::ui;
EightBallLayer::EightBallLayer()
{
}
EightBallLayer::~EightBallLayer()
{
}
bool EightBallLayer::init()
{
auto bb = ImageView::create(“xxx.png”, Widget::TextureResType::LOCAL);
bb->setTouchEnabled(true);
bb->setPosition(VisibleRect::center());
bb->addTouchEventListener(CC_CALLBACK_2(EightBallLayer::touchEvent, this));
this->addChild(bb);
return true;
}
void EightBallLayer::touchEvent(cocos2d::Ref pSender, Widget::TouchEventType type)
{
Node sender = dynamic_cast<Node*>(pSender);
if (sender == nullptr)
return;
int tag = sender->getTag();
switch (type)
{
case Widget::TouchEventType::BEGAN:
sender->setScale(1.05f);
break;
case Widget::TouchEventType::MOVED:
break;
case Widget::TouchEventType::ENDED:
sender->setScale(1.0f);
//AudioMgr::getInstance()->playClickEffect();
break;
case Widget::TouchEventType::CANCELED:
sender->setScale(1.0f);
break;
default:
break;
}
}
void EightBallLayer::onEnter()
{
}
void EightBallLayer::onExit()
{
}

=============================================================================

In hellow world scene.

=============================================================================

auto layer = EightBallLayer::create();
this->addChild(layer);

=============================================================================

Then I found that the event not response.

Sorry I tried my best, I can’t adjust this format.

So what are you trying to touch? The ImageView or the Layer?

#10

ImageView, But the breakpoint has never hit.

#11

Try running Cpp-tests

#12

It’s Okay, But the base classes are always scene in cpp test cases. I tried in layer it’s not work so that I don’t know why.

#13

Attach your whole class and header please. If I can drop them into a test project I will.

#14

I will upload the attachment tomorrow, the computer is not around. Thanks.

#15

Sure, I will be happy to test this out.

#16

After studying for one morning, it was originally necessary to call node’s onEnter and onExit in the onEnter and onExit functions in the derived class.

#18

So what is the status? Do I need to test this or not?
