动态连接/断开信号和插槽 [英] Dynamic connecting/disconnecting signals and slots

问题描述

我的程序有两个状态，由于某些原因它可以在两个状态之间切换.在这些状态下，程序需要接收不同的信号，这意味着它必须在运行期间连接和断开某些信号.

My program has two states and it can switch between them for some reasons. In these states the program needs to receive different signals, which means it has to connect and disconnect certain signals during the run.

这种方法有多糟糕?
