      No idea what your latest question means.... Nor why serial port/custom plot widgets have the faintest connection to mouse hover, other than you needing to write whatever code you need to write....

          Hi

          but widget mousehover when crccalculate error How Can I fixed

          This sentence dont really tell what is wrong.

          Also what is crccalculate ?

          Maybe a picture will help us understand what you need to fix or do ?

            When I hover over the widget with the mouse while reading the serial port data, I get an error in the Crc32 calculation. That is, when the mouse moves, while reading the serial port at a speed of 5 megabits

              Ok, that way. well you could set the button to disabled so remove the hovering effect but
              it sounds very odd that such a small effect would give you CRC errors.

                  Example code for what? And we expect you to write the code and ask questions, not just ask others to write it for you.

                      No, you need to do some reading of the documentation, try some things, and write questions which people can understand, even if English is not your native language.

                            hi
                            Its very helpful to be able to use the docs.
                            anyway, try
                            ui->buttoname->setEnabled(false);

                            the button should show a bit grey and no hover effect.

                                Hi
                                That is hard to guess on as why would a hover eefct break the CRC calculation in first place ?

                                Did you watch your cpu usage ? is it at 100% ?

                                      Ok so its not using 100% cpu so its not due to the hover disturbs it.

                                      Does it happen every time if you hover something?

                                      Do you use StyleSheets in your app ?

                                          Ok so its not due to the stylesheet which can be heavy.

                                          And what happened when you disabled the button ?
                                          It went grey looking and no hover effect ?
