    I have an object that emits lots of signals. How can I block just one signal of this object?

      Hi,

      The less complex idea that comes to mind is: you can use a Boolean variable as enabler and if false don't emit the signal.

          @Amanda1102 The options that I am aware of would be the following:

          1. QSignalBlocker: This approach will block all signals coming from a specific object
          2. disconnect: You can call "disconnect" on the specific signal you don't want for a short period of time and then call on "connect" again for the signal again.
          3. The approach mentioned by @SGaist
