In Delphi I remember the use of Tthread.synchronize (Tthreadmethod), the principle is to use a hidden window to deal with.In QT debug mode, the same problem is encountered, showing the error:Cannot send events to objects owned by a different threadThe solution is to use the signal slot, which is the constant signal in the thread, and the slot function of the UI threads is constantly receiving signals and processing:So as a solution I would propose the
