Embodiment Construction

[0024] refer to figure 1 , figure 1 It is a schematic flowchart of a preferred embodiment of the synchronous display method of the present invention. The synchronous display method of this embodiment is preferably applied to a QT embedded system, which includes but not limited to the following steps.

[0025] Step S200, triggering a target QT drawing event for displaying the first display content.

[0026] Step S210, execute the drawing function corresponding to the QT drawing event, and trigger the predefined first trigger event at the same time.

[0027] Wherein, the first trigger event is used to trigger the frame buffer operation of displaying the second display content, the second display content and the first display content are contents that need to be displayed synchronously, and the first display content and the second display content are passed through the display device to display synchronously.

[0028] Step S220, synchronously displaying the first display conte...

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.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a QT embedded-based synchronous display method, a QT embedded-based synchronous display system, and a numerically controlled machine tool. Background technique [0002] In the prior art, the Qt Embedded system is the embedded version system of the graphical interface development tool QT, that is, the embedded graphical interface development tool system, which is connected to the Linux I / O interface and frame buffer (frame buffer, standard display device driver interface , that is, a display driver device) directly interacts, has high operating efficiency, and adopts object-oriented programming as a whole, and has a good architecture and programming mode. In a specific application, the QT Embedded system is used in the common software environment of the embedded hardware architecture, which has the advantage of cross-platform, and the same code can be applied to different...
