WebThe asynchronous (non-blocking) approach. Operations are scheduled and performed when the control returns to Qt's event loop. QSerialPort emits a signal when the operation is finished. For example, QSerialPort::write () returns immediately. When the data is sent to the serial port, QSerialPort emits bytesWritten (). WebFirst a new QCPGraphDataContainer is created and a shared pointer to it is assigned to mData. That initializes our storage area for data samples. mData = QSharedPointer (new QCPGraphDataContainer); Then the plot is configured and set up.
