    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 ?

                                    Not even the button ?
                                    It should be disabled unless something in code turns it on again.

                                        you cannot disable the mouse as its belongs to the OS.

                                        However you can hide it for your app

                                        QCursor cursor(Qt::BlankCursor);
                                        QApplication::setOverrideCursor(cursor);
                                        QApplication::changeOverrideCursor(cursor);
