Qlibrary isloaded
Web最重要的函数是 load () 用于动态加载库， isLoaded () 用于检查是否加载成功，以及 resolve () 来解析库中的符号。 如果库还没加载， resolve () 函数隐式地加载这个库。 多个QLibrary实例访问同一个物理库文件是可行的。 一旦被加载，库在内存中一直保留到程序结束。 您可以通过 unload () 尝试卸载一个库，但如果有其他QLibrary实例在使用同一个库文件，调用 … Loads the library and returns true if the library was loaded successfully; otherwise returns false. Since resolve() always calls this function before resolving any symbols it is not necessary to call it explicitly. In some situations you might want the library loaded in advance, in which case you would use this function.
