Missing reference in range-for with non trivial type (QString) [clazy-range-loop]

for 循环范围中（QString）[clazy range loop]的的范围中缺少引用

本质 QString imagePath 是个临时变量，每次for都要申请内存再销毁是没有必要的

//改后
void TextureLibrary::generateTexture(const QList<QString> &imagePathList)
{
    if (!m_glTextureList.isEmpty()){
        this->clearTexture();
    }
    for (auto &imagePath : imagePathList){
        this->appendGlTexture(imagePath);
    }
}

Slots named on_foo_bar are error prone [clazy-connect-by-name]

.ui 默认生成的槽就会报，不用管它

Call to virtual method ‘FlowLayout::takeAt’ during destruction bypasses virtual dispatch [clang-analyzer-optin.cplusplus.VirtualCall]

在类的构造和虚构中调用虚函数需要加类名

//改后
FlowLayout::~FlowLayout()
{
    QLayoutItem *item;
    while ((item = FlowLayout::takeAt(0)))
        delete item;
}

non-POD static (QString) [clazy-non-pod-global-static]

《Effective C++》
条款02 对于单纯常量，最好以const对象或enum替换#define；对于形似函数的宏，最好改用inline函数替换#define

Qt 中建议 Q_GLOBAL_STATIC , 我个人喜欢写到类的静态成员变量中

class A{
public:
	static QString _path;
};
QString A::_path = "xxx";
