利用CCControlButton创建一个Button,代码如下:
void MyBottonBastLayer::initLayer() {
CCSize size = CCDirector::sharedDirector()->getWinSize();
CCScale9Sprite *psc9Selected = CCScale9Sprite::create("btn-about-selected.png");
CCLabelTTF *label = CCLabelTTF::create("My Button", "Marker Felt", 30);
CCScale9Sprite *psc9ButtonBG = CCScale9Sprite::create("extensions/buttonHighlighted.png");
CCControlButton *button = CCControlButton::create(label, psc9ButtonBG);
/*set the button is pressed state*/
button->setPosition(ccp(500.0f, size.height / 3.0f));
button->setBackgroundSpriteForState(psc9Selected, CCControlStateSelected);
button->setTitleColorForState(ccWHITE, CCControlStateHighlighted);
button->addTargetWithActionForControlEvents(this, cccontrol_selector(MyBottonBastLayer::buttonCallBack), CCControlEventTouchDown);
this->addChild(button, 1);
}
其中:
button->addTargetWithActionForControlEvents(this, cccontrol_selector(MyBottonBastLayer::buttonCallBack), CCControlEventTouchDown);
是button所点击的时候产生的行为:
void MyBottonBastLayer::buttonCallBack(CCObject *object, CCControlEvent controlEvent) {
CCLOG("Touch the Button");
}
关于点击时,详细参数如下:
/* 当鼠标处于按下并曾经点中按钮时,则触发一次 */
controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchDownAction), CCControlEventTouchDown);
/* 当鼠标处于按下并曾经点中按钮的状态下,鼠标进入按钮范围,则触发一次 */
controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchDragEnter), CCControlEventTouchDragEnter);
/* 当鼠标处于按下并曾经点中按钮的状态下,鼠标离开按钮范围,则触发一次 */
controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchDragExit), CCControlEventTouchDragExit);
/* 当鼠标处于按下并曾经点中按钮的状态下,鼠标进入按钮范围,则触发,只要达到条件,就不断触发 */
controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchDragInside), CCControlEventTouchDragInside);
/* 当鼠标处于按下并曾经点中按钮的状态下,鼠标离开按钮范围,则触发,只要达到条件,就不断触发 */
controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchDragOutside), CCControlEventTouchDragOutside);
/* 当鼠标处于按下并曾经点中按钮的状态下,鼠标松开且在按钮范围内,则触发一次 */
controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchUpInside), CCControlEventTouchUpInside);
/* 当鼠标处于按下并曾经点中按钮的状态下,鼠标松开且在按钮范围外,则触发一次 */
controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchUpOutside), CCControlEventTouchUpOutside);
/* 暂时没有发现能用鼠标触发这个事件的操作,看了注释,应该是由其它事件中断按钮事件而触发的 */
controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchCancel), CCControlEventTouchCancel);
