9、CCControlButton的实现

boolHelloWorld::init()

{

if ( !CCLayer::init() )

{

return false;

}

CCLabelTTF*titleButton = CCLabelTTF::create("未选中文字", "Marker Felt", 25);

CCControlButton *btn =CCControlButton::create(titleButton,CCScale9Sprite::create("button.png"));

btn->setPosition(ccp(240,170));

//按钮被选中后背景图响应的状态

btn->setBackgroundSpriteForState(CCScale9Sprite::create("buttonHighlighted.png"),CCControlStateHighlighted);

//按钮被选中后文字颜色响应的状态

btn->setTitleColorForState(ccc3(255,0, 0), CCControlStateHighlighted);

//按钮被选中后文字响应的状态

btn->setTitleForState(CCString::create("选中文字"), CCControlStateHighlighted);

addChild(btn);

//按钮按下事件回调

btn->addTargetWithActionForControlEvent(this,cccontrol_selector(HelloWorld::touchDownAction), CCControlEventTouchDown);

//按钮在其内部抬起事件回调

btn->addTargetWithActionForControlEvent(this,cccontrol_selector(HelloWorld::touchUpInsideAction),CCControlEventTouchUpInside);

//按钮在其外部抬起事件回调

btn->addTargetWithActionForControlEvent(this,cccontrol_selector(HelloWorld::touchUpOutsideAction),CCControlEventTouchUpOutside);

//用于显示按钮状态

CCLabelTTF*titleButtonState = CCLabelTTF::create("", "Marker Felt",25);

addChild(titleButtonState,0,923);

titleButtonState->setPosition(ccp(240,220));

return true;

}

voidHelloWorld::touchDownAction(CCObject *senderz, CCControlEvent controlEvent)

{

CCLabelTTF*m_pDisplayValueLabel = (CCLabelTTF*)this->getChildByTag(923);

m_pDisplayValueLabel->setString(CCString::createWithFormat("按下")->getCString());

}

voidHelloWorld::touchUpInsideAction(CCObject *sender, CCControlEvent controlEvent)

{

CCLabelTTF *m_pDisplayValueLabel =(CCLabelTTF*)this->getChildByTag(923);

m_pDisplayValueLabel->setString(CCString::createWithFormat("内部抬起")->getCString());

}

voidHelloWorld::touchUpOutsideAction(CCObject *sender, CCControlEvent controlEvent)

{

CCLabelTTF*m_pDisplayValueLabel = (CCLabelTTF*)this->getChildByTag(923);

m_pDisplayValueLabel->setString(CCString::createWithFormat("外部抬起")->getCString());

}
