QByteArray在主要以下两种情况中使用:需要存储原始二进制数据时和在内存保护至关重要时(例如,对于嵌入式Linux使用Qt)。 初始化QByteArray的一种方法就是将一个 const char * 传递给其构造函数。 QByteArray byte("Hello"); qDebug()<<byte.data(); qDebug()<<byte.size(); byte大小为5,数据为 “Hello”...

With this approach, the container is stored as a regular array of objects, but the index of each element is used as the key to construct the container when reading it back in. QJsonObject Level::toJson() const { QJsonObject json; json["name"] = mName; QJsonArray npcArray; for (...

String Literals are handled as UTF-8. String literal Convert to Stack Variable Converts the selected pointer to a stack variable. For example, rewrites: QByteArray *foo = new QByteArray("foo"); foo->append("bar"); as QByteArray foo = "foo"; foo.append("bar"); This operation is ...
