The application relates to the technical field of node graphical programming, in particular to a graphical use case generation method and device, a vehicle and a storage medium, wherein the method comprises the following steps: a click event of a mouse on a canvas is listened to, and first position coordinates of a source node port are acquired; at least one candidate node port is filtered from the canvas according to current position coordinates of the mouse in a dragging process of the source node port, and a target node port is determined from the candidate node ports according to second position coordinates of the candidate node ports and the current position coordinates of the mouse; a connection line data structure is created according to the first position coordinates of the source node port and third position coordinates of the target node port, and a graphical use case is generated according to an editing result of the target node port and the connection line data structure. Therefore, the problems that in the related art, a manual connection node operation of a drawing tool is complicated, precision is poor, and modeling efficiency is low and the like are solved.

The present disclosure relates to devices, methods, and graphical user interfaces for annotating content. According to some embodiments, a method is disclosed herein as being performed on a device having one or more processors, non-transitory memory, a display, and an input device. The method includes displaying, on the display, a drawing user interface that includes a plurality of drawing objects. When a drawing tool associated with a predefined operation is selected, the method includes detecting, via the one or more input devices, user input that moves to define a path within the drawing user interface. In response to detecting the user input that moves to define the path within the drawing user interface, the method includes performing the predefined operation with respect to two or more of the plurality of drawing objects that intersect the path.

This application discloses a method, apparatus, device, and system for driving multiple processes in drawing files, belonging to the field of drawing tool technology. The method includes: obtaining a task queue to be executed by the drawing tool, the task queue including a first transaction and a second transaction; while driving the first process of the drawing tool to execute the first transaction, executing the second transaction by driving the second process of the drawing tool during an idle time period, the idle time period being the idle time period during the execution of the first transaction by the first process. In this way, by driving one process to execute one transaction while driving another process to execute another transaction during an idle time period, it is possible to simultaneously drive multiple processes to execute transactions in parallel, fully utilizing the idle time period of the drawing tool itself, thereby reducing the total execution time of multiple transactions and improving the design efficiency of drawing files.
