Abstract
The present disclosure provides a simultaneous display method, system, and computer numerical control machine tool based on QT embedded. The method includes triggering a target QT paint event which displays a first display content; executing a drawing function corresponding to the QT paint event, and meanwhile, triggering a predefined first triggering event; wherein, the first triggering event is used to trigger a frame buffer operation to display a second display content, and the second display content and the first display content are contents required to be simultaneously displayed; displaying the first display content and the second display content simultaneously by a display device. The present disclosure can guarantee that the frame buffer operation is executed after executing the target QT paint event, to ensure that the frame buffer operation and QT embedded drawing are displayed simultaneously, avoiding displaying errors and improving the user experience.
