My question, how to update qt creator and qt?我的问题，如何更新 qt 创建者和 qt？ Is there any button on qt creator or function in make or qmake to update from 4.6.x to 4.7.xxx? qt creator 或 function 在 make 或 qmake 上是否有任何按钮可以从 4.6.x 更新到 4.7.xxx？
If I will download new version from official site I will duplicate all that things as qt creator, linguist, assinstent and designer, and fear to be confused which version I using in development.如果我要从官方网站下载新版本，我会将所有内容复制为 qt 的创建者、语言学家、助理和设计师，并且害怕混淆我在开发中使用的版本。
