@inusion yourProject.pro 파일에 다음 내용을 넣으셨나요? QT += serialbus 다음 코드를 h/hpp 나 cpp/cxx 에 추가하셨나요? #include <QCanBus> 당신의 Qt 는 Qt 5.8 이상의 버전인가요? Qt 를 설치 시에 serial 관련 내용을 함께 설치하셨나요?

@ds3216 said in qprogessbar question!!!: is being updated normally What do you mean by that? The most common approach I know, is to do some work inside a loop and call setValue() on the QProgressBar. Usually, that loop is inside the main thread which also happens to be the GUI thread. This basically prevents the event loop from handling the update of the progress bar. The easiest way to test this is to put QApplication::processEvents() right after calling setValue() (or setFormat()). This is not the best solution and will heavily slow down your application. So, don't leave it inside your code. Once you confirm that this is the problem, we can help out with a better solution. In that case we would need more context how and when you are calling setValue().

@Freemize pyside6.3.1 버젼에서 쌍자음 버그 해결 되었네요

@A-A-SEZEN Thank you. I've solved it in a different way, not the same way.

버튼을 만드시고 connect(button,SIGNAL(clicked()),this,SLOT(charton)); void MainWindow::charton(){ Qdockwidget* qdockwidget; layout->setwidget(chart); qdockwidget->setlayout(layout); qdock을 원하는 위치에 놓으시면 됩니다. qt를 안키고 작성해서 정리가 안되있는데 흐름은 맞습니당 }
