CCButton - not use CCMenu

I refer to http://www.cocos2d-x.org/boards/6/topics/1090?r=7731
and then make CCButton to be more similar to UIButton

here is some example

1:

CCButton * tmpBtn = CCButton::buttonWithFiles(this,menu_selector(HelloWorld::menuCloseCallback), "shop_btn.png", "shop_btn_click.png", NULL);
tmpBtn->setTitleForState("Show", CCControlStateNormal);
this->addChild(tmpBtn);
tmpBtn->setPosition(ccp(50,50));

2:

    CCSprite * tmpBgSprite = CCSprite::spriteWithFile("shop_btn.png");
    CCSprite * tmpBgSprite2 = CCSprite::spriteWithFile("shop_btn_click.png");

    CCButton * tmpBtn = CCButton::buttonWithFiles(this,menu_selector(HelloWorld::menuCloseCallback), NULL,NULL, NULL);
    tmpBtn->setBackgroundImageForState(tmpBgSprite, CCControlStateNormal);
    tmpBtn->setBackgroundImageForState(tmpBgSprite2, CCControlStateSelected);

    tmpBtn->setTitleForState("Show", CCControlStateNormal);

    this->addChild(tmpBtn);
    tmpBtn->setPosition(ccp(50,50));

3:

    CCButton * tmpBtn = CCButton::buttonWithFiles(this,menu_selector(HelloWorld::menuCloseCallback), NULL,NULL, NULL);
    tmpBtn->setTitleForState("Show", CCControlStateNormal);
    this->addChild(tmpBtn);
    tmpBtn->setPosition(ccp(50,50));

4:

CCButton * tmpBtn = CCButton::buttonWithFiles(this,menu_selector(HelloWorld::menuCloseCallback), "shop_btn.png", "shop_btn_click.png", NULL);
this->addChild(tmpBtn);
tmpBtn->setPosition(ccp(50,50)); 

here is the header file

#pragma once
#include "cocos2d.h"
#define TAP_MAX_DRAG 10

using namespace cocos2d;


enum {
    CCControlStateNormal       = 0,
    CCControlStateSelected     = 1 << 0,                  // flag usable by app (see below)
    CCControlStateDisabled     = 1 << 1,
    CCControlStateHighlighted  = 1 << 2                 // todo
};
typedef unsigned int CCControlState;


class CCButton : public CCNode, public CCTargetedTouchDelegate
{
private:
    bool initWithFile(const char* filename, SelectorProtocol* target, SEL_MenuHandler selector);
    SelectorProtocol* target;
    SEL_MenuHandler selector;
    bool touched;
    CCPoint touchPoint;

    bool isDisabled;

    CCControlState curState;

    CCMutableDictionary * backgroundNodes; //zOrder is 0
    CCMutableDictionary * touchNodes;      //zOrder is 1
    CCMutableDictionary * titleCCStrings;  //zOrder is 2

    void setState(CCControlState mState);

public:
    CCButton();
    ~CCButton();

    void initWithFile(SelectorProtocol* target, SEL_MenuHandler selector,const char * mNormal,const char * mSelected,const char * mDisabled=NULL);
    static CCButton * buttonWithFiles(SelectorProtocol* target, SEL_MenuHandler selector,const char * mNormal,const char * mSelected,const char * mDisabled=NULL);


    void setTitleForState(const char * mTitle,CCControlState mState);
    const char* titleForState(CCControlState mState);

    void setDisable(bool mIsDisabled);

    //todo
    virtual void setTitleColorForState(ccColor3B mColor,CCControlState mState){CC_UNUSED_PARAM(mColor);CC_UNUSED_PARAM(mState);};
    virtual ccColor3B titleColorForState(CCControlState mState){CC_UNUSED_PARAM(mState);return ccYELLOW;};

    void setImageForState(CCNode* mNode,CCControlState mState);
    CCNode * imageForState(CCControlState mState);
    void setBackgroundImageForState(CCNode *mNode,CCControlState mState);// default is NULL
    CCNode * backgroundImageForState(CCControlState mState);

    // touch events
    CCRect rect();
    bool containsTouchLocation(CCTouch* touch);
    virtual void onEnter();
    virtual void onExit();
    virtual bool ccTouchBegan(CCTouch* pTouch, CCEvent* pEvent);
    virtual void ccTouchMoved(CCTouch* pTouch, CCEvent* pEvent);

    virtual void ccTouchCancelled(CCTouch *pTouch, CCEvent *pEvent);

    virtual void touchDelegateRelease();
};

Great extension. I’m considering to create a new sub-forum for extension discussion….

Less is More. Keep Focus.

For the latest stable version, should we change SelectorProtocol to CCObject?

yes, you can change SelectorProtocol to CCObject.
i had test it for the latest stable version

Hey man,
awesome piece of work. Thanks a lot!

Only pity is that you use “using namespace cocos2d” in a header file. This is something you shouldn’t do, as each file which will include CCButton will include using namespace cocos2d and all following files as well. Second, it would be cool if you could wrap extensions in your own namespace like cocos2d_ext or something. Than its easier to distinguish!

Besides that.. Great job!

I updated the cocos2d-extensions with your CCButton component. There is a bug in win32, maybe you can solve it and submit a patch.

So, it’s better to use this CCButton instead of CCMenu?

@Jose Antonio Andujar Why your extensions aren’t merged to cocos repo? :(

@Dawid Drozd

I haven’t updated the extensions a long time ago.

I’m sure they need a lot of work for cross-platform working, and I’m not sure that will be accepted for a pull request.
