cocos2dx之彩色编辑输入框的设计(2)

再来具体看看实现部分：

首先初始化：

bool ColorEdit::myInit(Scale9Sprite * pBgSprite,Node * parent,EditLocation editLocation,EditType editType)
{
	if (!Layer::init())
	{
		return false;
	}
	m_pEditBg = pBgSprite;
	m_pTarget = parent;
	m_editLocation = editLocation;
	m_editType = editType;

	this->addChild(m_pEditBg);
	auto centerSize = m_pEditBg->getContentSize();
	//这里要设置好九宫图中间的矩形的大小，因为我们要把输入的内容显示在上面，否则会看起来乱七八糟
	m_pEditBg->setCapInsets(Rect(0,0,centerSize.width * 0.9,centerSize.height * 0.9));
	auto pLabel = Label::createWithTTF(,fonts/Marker Felt.ttf,centerSize.height * 0.75);
	pLabel->setColor(Color3B::WHITE);
	pLabel->setAnchorPoint(Vec2(0,0.5));
	pLabel->setTag(103);
	pLabel->setPosition(Vec2(centerSize.width * 0.08,centerSize.height * 0.5));
	m_pEditBg->addChild(pLabel,2);
	//如果是全屏显示类型
	if (m_editLocation == Location_Screen)
	{
		//添加阴影层，先隐藏
		auto keyLayer = LayerColor::create(Color4B(0,0,0,100));
		keyLayer->setPosition(Point::ZERO);
		keyLayer->setTag(100);
		m_pTarget->addChild(keyLayer,this->getMaxZOrder(parent) + 2);
		keyLayer->setVisible(false);
		//添加上方的输入框
		auto key_bigbg = Scale9Sprite::create(coloredit/key_bigbg.png);
		key_bigbg->setContentSize(Size(Director::getInstance()->getWinSize().width,key_bigbg->getContentSize().height));
		key_bigbg->setTag(101);
		key_bigbg->setAnchorPoint(Vec2(0.5,0));
		auto upSize = key_bigbg->getContentSize();
		key_bigbg->setPosition(Vec2(m_pTarget->getContentSize().width / 2,m_pTarget->getContentSize().height));
		m_pTarget->addChild(key_bigbg,this->getMaxZOrder(parent) + 2);
		//同样设置九宫图中间的矩形
		key_bigbg->setCapInsets(Rect(0,0,upSize.width * 0.9,upSize.height * 0.9));
		auto label_up = Label::createWithTTF(,fonts/Marker Felt.ttf,upSize.height * 0.75);
		label_up->setColor(Color3B::WHITE);
		label_up->setAnchorPoint(Vec2(0,0.5));
		label_up->setTag(102);
		label_up->setPosition(Vec2(upSize.width * 0.08,upSize.height / 2));
		key_bigbg->addChild(label_up);
	}

	m_keyBg = Sprite::create(coloredit/key_bg.png);
	m_keyBg->setAnchorPoint(Vec2(0.5,1));
	m_keyBg->setPosition(Vec2(m_pTarget->getContentSize().width / 2,0));
	m_pTarget->addChild(m_keyBg,this->getMaxZOrder(parent) + 2);

	auto bgSize = m_keyBg->getContentSize();
	auto pMenu = Menu::create();
	pMenu->setPosition(Vec2::ZERO);
	m_keyBg->addChild(pMenu);
	if (m_editType == Edit_Number)//添加数字键盘
	{
		for (int i = 0; i < 2; i++)
		{
			for (int j = 0; j < 5; j++)
			{
				auto numSprNor = Sprite::create(__String::createWithFormat(coloredit/num_%d.png,i * 5 + j)->getCString());
				auto numSprSel = Sprite::create(__String::createWithFormat(coloredit/num_%d.png,i * 5 + j)->getCString());
				auto numBtn = MenuItemSprite::create(numSprNor,numSprSel,CC_CALLBACK_1(ColorEdit::onNumBtnCallback,this));
				numBtn->setTag(Key_Num_0 + i * 5 + j);

				numBtn->setPosition(Vec2(bgSize.width / 10 * (j * 2 + 1),bgSize.height / 6 * ((3 - i) * 2 - 1)));
				pMenu->addChild(numBtn);
			}
		}

		auto delSprNor = Sprite::create(coloredit/btn_del.png);
		auto delSprSel = Sprite::create(coloredit/btn_del.png);
		auto delBtn = MenuItemSprite::create(delSprNor,delSprSel,CC_CALLBACK_1(ColorEdit::onFunBtnCallback,this));
		delBtn->setTag(Key_Delete);
		delBtn->setPosition(Vec2(bgSize.width / 4 - 15,bgSize.height / 6));
		pMenu->addChild(delBtn);

		auto sureSprNor = Sprite::create(coloredit/btn_sure.png);
		auto sureSprSel = Sprite::create(coloredit/btn_sure.png);
		auto sureBtn = MenuItemSprite::create(sureSprNor,sureSprSel,CC_CALLBACK_1(ColorEdit::onFunBtnCallback,this));
		sureBtn->setTag(Key_Sure);
		sureBtn->setPosition(Vec2(bgSize.width / 4 * 3 + 15,bgSize.height / 6));
		pMenu->addChild(sureBtn);
	}
	else if (m_editType == Edit_Alphabet)//和number差不多，多了些按钮而已
	{
	}
	else if (m_editType == Edit_PinYin)//这个要是实现的话，就成输入法了，咱们还是调用系统的吧。
	{
	}

	//简单暴力的屏幕适配
	auto rate_x = Director::getInstance()->getWinSize().width / bgSize.width;
	m_keyBg->setScaleX(rate_x);

	auto listenerT = EventListenerTouchOneByOne::create();
	listenerT->onTouchBegan = CC_CALLBACK_2(ColorEdit::onTouchBegan,this);
	listenerT->setSwallowTouches(false);
	Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listenerT,this);

	return true;
