CCMutableArray<CCLayer*> layers;
layers.addObject(layer1);
layers.addObject(layer2);
layers.addObject(layer3);
layers.addObject(layer4);
layers.addObject(layer5);

CCScrollLayer* pScrollLayer = CCScrollLayer::layerWithLayers(&layers, 0);
pScrollLayer->setPosition(ccp(0,0));
addChild(pScrollLayer);

i used the above code for CCScrollLayerButton and CCScrollLayer, but what we have to use CCScrollLayerEX code.

The CCScrollLayerExt is not working as expected…
I just create a new Layer as:
@
ScrollLayerExt *scroll = new ScrollLayerExt(CCRect::CCRectMake(0,0,960,640));
this->addChild(scroll);
@

It adds a gray colored layer to the screen but when I swipe on the screen, the layer comes back to the original place after I leave it , even though I have not reached the end of the layer. Any help is appreciated.

Thanks.

I am having some issues with Creating a CCScrollLayerButton, assigning a tag to it then reading that tag in my callback function.
when i try and get the tag i am getting an EXEC_BAD_ACCESS exception.
I doing the following:

CCScrollLayerButton* levelButton = CCScrollLayerButton::buttonWithFile( “CompleteLevel.png”, this, menu_selector(LevelSelectionScene::callfunc));
levelButton~~>node~~>setTag;
levelButton~~>setAnchorPoint);
levelButton~~>setPosition(GetLevelPosition(3));
layer~~>addChild;
and the callFunc looks as follows:

void LevelSelectionScene::callfunc
{
int tagNum = pSender~~>getTag();
}

any help would be much appreciated.

CCScrollLayerExt::setContentLayerSize(CCSize mSize) can set the size for scroll layer!
so you had to set the right size for it.

Does anybody have CCScrollLayer class ported to cocos2d-x v2.xx ?
