1.cocos2dx之Menu(CCMenuItemFont,CCMenuItemImage,CCMenuItemLabel,CCMenuItemSprite,CCMenuItemToggle)

Ccmenu

基本结构

Ccmenu继承自cclayer,本质是一个容器。需要被addChild到父类中去。

CcmenuItem是菜单项，它有如下子类：

CcmenuItemFont;CcmenuItemImage;CcmenuItemLabel;CcmenuItemSprite;CcmenuItemToggle;

是真正的需要实例化的菜单项。需要addChild到Ccmenu对象中去。

示例：

CcmenuItem * item = CcmenuItemFont::create(“Start”);

//这里的this表示的是调用者

Item->setTarget(this,menu_selector(MYMenu::menuCallBack));

Ccmenu * menu = Ccmenu::create();

menu->addChild(item);

addChild(menu);

CcmenuItem

A CcmenuItemFont

CcmenuItem * font = CcmenuItemFont::create(“Start”,this,menu_selector(MYMenu::menuCallBack));

Ccmenu * menu = Ccmenu::create();

menu->addChild(item);

addChild(menu);

第一个参数为标签要显示的文字，第二个参数表示回调函数的调用者，第三个参数表示回调函数。

关于回调

typedef void (CCObject::*SEL_MenuHandler)(CCObject *);

#define menu_selector(_SELECTOR)(SEL_MenuHandler)(&_SELECTOR)

B Ccmenu的坐标系统研究

fontItem->setPosition(ccp(winSize.width – 50,30));

menu->setPosition(CCPointZero);

cclog("fontItem = %g %g",fontItem->getPositionX(),fontItem->getPositionY());

cclog("menu = %g,%g,width %g,height = %g",menu->getPositionX(),menu->getPositionY(),

menu->getContentSize().width,menu->getContentSize().height);

CCcmenuItemImage

CcmenuItem *imageItem = CcmenuItemImage::create(“Closenormal.png”,”CloseSelected.png”);

imageItem->setTarget(this,menu_selector(Menu::menuCallBack));

第1个参数为末点击是显示的图片，第二个参数为点击后显示的图片，最后参数可以放到setTarget中，意义同上。

D CcmenuItemLabel

cclabelBMFont *bm = cclabelBMFont::create("bmFontLabelMenu",

"fonts/bitmapFontTest.fnt");

CcmenuItem * labelItem = CcmenuItemLabel::create(bm,menu_selector(MYMenu::menuCallBack));

menu->addChild(labelItem);

第一个参数为一个label，最后两个参数同上。

E CcmenuItemSprite

CCSprite * normal = CCSprite::create(“gonormal.png”);

CCSprite * selected = CCSprite::create(“goselected.png”);

CcmenuItemSprite * spriteItem = CcmenuItemSprite::create(normal,selected,menu_selector(MYMenu::menuCallBack));

menu->addChild(spriteItem);

第一个参数和第二个参数为CCSprite后面的参数，同上。

CcmenuItemToggle

CcmenuItem *t1 = CcmenuItemFont::create("ON");

CcmenuItem *t2 = CcmenuItemFont::create("OFF");

CcmenuItem *t3 = CcmenuItemFont::create("10%");

CcmenuItem *t4 = CcmenuItemFont::create("50%");

CcmenuItemToggle * toggle =

CcmenuItemToggle::createWithTarget(this,

menu_selector(T11Menu::menuCallBack),t1,t2,t3,t4,NULL);

menu->addChild(toggle);

第一个和第二个参数为回调函数调用者和回调函数，后面的参数为CcmenuItem.可以实现变化的菜单。

如何判断哪个菜单被点

打Tag

CCArray * array = menu->getChildren();

CCObject * obj;

int i = 0;

CCARRAY_FOREACH(array,obj)

{

CcmenuItem * item = (CcmenuItem *)obj;

item->setTag(i + 1000);

i++;

}

找Tag

CcmenuItem * item = (CcmenuItem *)obj;

Switch (item->getTag() - 1000) {

Case FONT1:

cclog(“CcmenuItemFont”);

break;

case FONT2:

break;

case IMAGE:

break;

case BM:

break;

case SPRITE:

break;

case TOGGLE:

{

int index = ((CcmenuItemToggle *)item)->getSelectedindex();

cclog(“index = %d”,index);

}

break;

}

案例说明：

MYMenu.h

#ifndef __MYMENU_H__

#define __MYMENU_H__

#include "cocos2d.h"

USING_NS_CC;

class MYMenu : public cclayer {

public:

CREATE_FUNC(MYMenu);

bool init();

static CCScene * scene();

void menuCallBack(CCObject * obj);

enum MENU

{

FONT1,FONT2,138); font-family:新宋体; font-size:9.5pt">IMAGE,138); font-family:新宋体; font-size:9.5pt">LABELLABEL,138); font-family:新宋体; font-size:9.5pt">SPRITE,138); font-family:新宋体; font-size:9.5pt">TOGGLE

};

Ccmenu * menu;

};

#endif

MYMenu.cpp

#include "MYMenu.h"

#include "AppMacros.h"

CCScene * MYMenu::scene()

{

scene = CCScene::create();

MYMenu * layer = create();

scene->addChild(layer);

return scene;

}

//五种菜单

#if 0

CcmenuItemFont;

CcmenuItemImage;

CcmenuItemLabel;

CcmenuItemSprite;

CcmenuItemToggle;

#endif

bool init()

{

cclayer::init();

//第1步：创建一个菜单

menu = Ccmenu::create();

//第2步：创建菜单项

//可以将下面的两行合并

CcmenuItem * fontItem = CcmenuItemFont::create("fontmenu");

fontItem->setTarget(this,138); font-family:新宋体; font-size:9.5pt">menu_selector(menuCallBack));

//显示menuItem在界面中的显示条项

cclog("first Item :x = %g y = %g",fontItem->getPositionX(),0); font-family:新宋体; font-size:9.5pt">getPositionY());

"first Item Anchor x = %g,y = %g",0); font-family:新宋体; font-size:9.5pt">getAnchorPoint().x,0); font-family:新宋体; font-size:9.5pt">getAnchorPoint().y);

"first Item ContentSize width %g hight %g",

fontItem->getContentSize().width,0); font-family:新宋体; font-size:9.5pt">getContentSize().height);

//创建第二个Menu条项

CcmenuItem * fontItem2 = "fontmenu2");

fontItem2->menuCallBack));

//设置Menu在界面中的显示状态

//menu->alignItemsverticallyWithPadding(40);

//显示menu在界面中的显示特征

"---------------------------------------------");

"Menu:x = %g,menu->"Menu Anchor x = %g y = %g",21); font-family:新宋体; font-size:9.5pt">"Menu ContentSize width %g high %g",

menu->getContentSize().height);

//第2步：创建CcmenuItemImage类型的菜单项

CcmenuItem *imageItem = CcmenuItemImage::"Closenormal.png","CloseSelected.png");

imageItem->menuCallBack));

//第2步：创建cclabelBMFont类型的菜单项

cclabelBMFont * bm = cclabelBMFont::"bmMenu",21); font-family:新宋体; font-size:9.5pt">"fonts/bitmapFontTest.fnt");

CcmenuItem *labelItem = CcmenuItemLabel::create(bm);

labelItem->menuCallBack));

//第2步：创建CCSprite类型的菜单项

CCSprite *nor = CCSprite::"btn_go_1.png");

CCSprite *sel = "btn_go_0.png");

CcmenuItem * sprItem = CcmenuItemSprite::create(nor,sel);

sprItem->menuCallBack));

//第2步：创建CcmenuItemToggle类型的菜单项

CcmenuItem * t1 = "ON");

CcmenuItem * t2 = "OFF");

CcmenuItem * t3 = "10%");

CcmenuItem * t4 = "%50%");

CcmenuItem * toggle = CcmenuItemToggle::createWithTarget(this,

menuCallBack),

t1,t2,t3,t4,138); font-family:新宋体; font-size:9.5pt">NULL);

//第3步：将菜单项添加到菜单中去

menu->addChild(fontItem);

menu->addChild(fontItem2);

menu->addChild(imageItem);

menu->addChild(labelItem);

menu->addChild(sprItem);

menu->addChild(toggle);

this->addChild(menu);

//第4步：设置菜单项的显示方式，让菜单项垂直显示

menu->alignItemsvertically();

//Ccmenu类有一个getChildren()方法可以得到菜单项

CCArray * array = menu->getChildren();

CCObject * obj;

int i = 0;

CCARRAY_FOREACH(array,obj)

{

CcmenuItem *item = (CcmenuItem *)obj;

item->setTag(i + 100);

i++;

}

for (int i = 0; i < array->count();++i)

{

CcmenuItem *item = (CcmenuItem *)array->objectAtIndex(i);

item->setTag(i);

}

return true;

}

//回调函数

void CCObject * obj)

{

CcmenuItem * item = (CcmenuItem *)obj;

switch (item->getTag() - 1000)

{

case FONT1:

"font menu call ");

break;

case FONT2:

break;

case IMAGE:

break;

case LABELLABEL:

break;

case TOGGLE:

int idx = ((CcmenuItemToggle *)item)->getSelectedindex();

"index = %d",idx);

break;

}

运行结果：

<el-menu>菜单标签（里面可以包括：<el-submenu>和<el-menu-item>）

<el-menu>

1、router属性，若使用router属性menu-item的index将对应router的path属性

2、mode,下拉菜单的模式分为horizontal和vertical两种模式

3、background-color，background-color属性为下拉菜单整体的背景颜色

4、text-color，text-color为下拉菜单中的文字的颜色

5、active-text-color为选中的菜单的颜色

<el-menu>标签中可以有el-submenu和el-menu-item标签组成

demo

<el-menu :router="true" mode="horizontal" background-color="#1c213f" text-color="#fff">
    <el-submenu index="1">
      <template slot="title">
        <i></i>
      </template>
      <el-menu-item index="1-1">选项一</el-menu-item>
      <el-submenu index="2">
        <template slot="title">选项二</template>
       <el-menu-item index="2-1">选项二-一</el-menu-item>
    </el-submenu>
</el-menu>
