cocos2d-x RichText 真实高度

cocos2d-x版本 3.8

在RichText自动换行后，发现不能得到真实高度，查看源码发现算出了实际高度，但确没用上，都多少个版本了，还没完善

void RichText::formarRenderers()
{
if (_ignoreSize)
{
float newContentSizeWidth = 0.0f;
float newContentSizeHeight = 0.0f;

Vector<Node*>* row = (_elementRenders[0]);
float nextPosX = 0.0f;
for (ssize_t j=0; j<row->size(); j++)
{
Node* l = row->at(j);
l->setAnchorPoint(Vec2::ZERO);
l->setPosition(nextPosX, 0.0f);
this->addProtectedChild(l, 1);
Size iSize = l->getContentSize();
newContentSizeWidth += iSize.width;
newContentSizeHeight = MAX(newContentSizeHeight, iSize.height);
nextPosX += iSize.width;
}
this->setContentSize(Size(newContentSizeWidth, newContentSizeHeight));
}
else
{
float newContentSizeHeight = 0.0f;
float *maxHeights = new float[_elementRenders.size()];

for (size_t i=0; i<_elementRenders.size(); i++)
{
Vector<Node*>* row = (_elementRenders[i]);
float maxHeight = 0.0f;
for (ssize_t j=0; j<row->size(); j++)
{
Node* l = row->at(j);
maxHeight = MAX(l->getContentSize().height, maxHeight);
}
maxHeights[i] = maxHeight;
newContentSizeHeight += maxHeights[i];//这里 算出了实际高度，但确没用上
}

float nextPosY = _customSize.height;
for (size_t i=0; i<_elementRenders.size(); i++)
{
Vector<Node*>* row = (_elementRenders[i]);
float nextPosX = 0.0f;
nextPosY -= (maxHeights[i] + _verticalSpace);

for (ssize_t j=0; j<row->size(); j++)
{
Node* l = row->at(j);
l->setAnchorPoint(Vec2::ZERO);
l->setPosition(nextPosX, nextPosY);
this->addProtectedChild(l, 1);
nextPosX += l->getContentSize().width;
}
}
delete [] maxHeights;
}

size_t length = _elementRenders.size();
for (size_t i = 0; i<length; i++)
{
Vector<Node*>* l = _elementRenders[i];
l->clear();
delete l;
}
_elementRenders.clear();

if (_ignoreSize)
{
Size s = getVirtualRendererSize();
this->setContentSize(s);
}
else
{
this->setContentSize(_customSize);
}
updateContentSizeWithTextureSize(_contentSize);
}

只有自己动手了
在RichText.h中加

Size _renderSize;
Size& getRenderSize();
void setRenderSize(const Size &size);

在RichText.cpp中改formarRenderers()

void RichText::formarRenderers()
{
if (_ignoreSize)
{
float newContentSizeWidth = 0.0f;
float newContentSizeHeight = 0.0f;

Vector<Node*>* row = (_elementRenders[0]);
float nextPosX = 0.0f;
for (ssize_t j=0; j<row->size(); j++)
{
Node* l = row->at(j);
l->setAnchorPoint(Vec2::ZERO);
l->setPosition(nextPosX, 0.0f);
this->addProtectedChild(l, 1);
Size iSize = l->getContentSize();
newContentSizeWidth += iSize.width;
newContentSizeHeight = MAX(newContentSizeHeight, iSize.height);
nextPosX += iSize.width;
}
this->setContentSize(Size(newContentSizeWidth, newContentSizeHeight));
this->setRenderSize(Size(newContentSizeWidth, newContentSizeHeight));  //这里加一行
}
else
{
float newContentSizeHeight = 0.0f;
float *maxHeights = new float[_elementRenders.size()];

for (size_t i=0; i<_elementRenders.size(); i++)
{
Vector<Node*>* row = (_elementRenders[i]);
float maxHeight = 0.0f;
for (ssize_t j=0; j<row->size(); j++)
{
Node* l = row->at(j);
maxHeight = MAX(l->getContentSize().height, maxHeight);
}
maxHeights[i] = maxHeight;
newContentSizeHeight += maxHeights[i];
}

float nextPosY = _customSize.height;
for (size_t i=0; i<_elementRenders.size(); i++)
{
Vector<Node*>* row = (_elementRenders[i]);
float nextPosX = 0.0f;
nextPosY -= (maxHeights[i] + _verticalSpace);

for (ssize_t j=0; j<row->size(); j++)
{
Node* l = row->at(j);
l->setAnchorPoint(Vec2::ZERO);
l->setPosition(nextPosX, nextPosY);
this->addProtectedChild(l, 1);
nextPosX += l->getContentSize().width;
}
}
this->setRenderSize(Size(_contentSize.width, newContentSizeHeight));//这里把没用上的newContentSizeHeight用上

delete [] maxHeights;
}

size_t length = _elementRenders.size();
for (size_t i = 0; i<length; i++)
{
Vector<Node*>* l = _elementRenders[i];
l->clear();
delete l;
}
_elementRenders.clear();

if (_ignoreSize)
{
Size s = getVirtualRendererSize();
this->setContentSize(s);
}
else
{
this->setContentSize(_customSize);
}
updateContentSizeWithTextureSize(_contentSize);
}

再实现

Size& RichText::getRenderSize()
{
return this->_renderSize;
}
void RichText::setRenderSize(const Size &size)
{
_renderSize = size;
}

OK了，实际高度有了，发现getReaderSize()还是不对，继续查源码

发现adaptRenderers()是在Widget的visit()里调用的，也就是说当前桢不会被调用，这就好办了，在RichText pushBackElement 之后显示的调用一下formatText()就OK了，
