In the embodiment of the disclosure, the size of the recording window is the same as the size of the application main window, the relative position of the area to be recorded is the same as the relative position of the area where the main application main window displays the image view, after the application main window receives the click event, it is determined whether the click position corresponding to the click event is on the image view, if so, the hierarchical view corresponding to the click position in the recording window is called to respond to the click operation, for example, a user clicks a button control in the image view, the click event is transmitted to the recording window, because the positions of the images on the recording window and the application main window are the same, the click event is transmitted to the recording window, the button control on the recording window is triggered, and the purpose of operating at least one hierarchical view in the application main window is achieved.
As an example of a scenario, taking an online education scenario as an example, the terminal described in the foregoing embodiment may be a terminal device at a teacher end, and the target device may be a terminal device at a student end. The display interface of the terminal device at the teacher end includes an application main window and a recording window, for example, the application main window shown in fig. 5A includes a courseware view, a camera view, a tool view, a courseware reduction view and the like, only an image of a courseware view is needed by the student end, the teacher end has other states to cover the courseware view, for example, as shown in fig. 5B, a release exercise view appearing in a popup window covers the original courseware view, therefore, the courseware view is collected according to the hierarchy when recording the screen, only the image of the courseware view is collected and placed on the recording window, for example, as shown in fig. 5C, the image of the courseware view is placed on the recording window, the recording window is completely under the application main window, the courseware view is placed on the recording window, that is placed on the same position as the application main window, the recording window at the bottom of the recording can obtain a video file only containing the courseware view, then, the blank areas are cut off, so that an image with only courseware view can be obtained and sent to the student, and the view of the courseware area interface is displayed on the student, as shown in fig. 5D.
The application main window completely covers the recording window, the courseware view is placed on the recording window, and the courseware view cannot be seen at the teacher end, so that the video file is required to be converted into the image view to be placed on the position area corresponding to the courseware view, the teacher and the students can see the images of the courseware area, and the application requirements are further met.
It will be appreciated that the courseware area may be operable, for example the courseware area may have a button control which is changed by clicking on the button, but the teacher may see the button control which will not function as the button control has become an image. The click event is from top to bottom in the system, and the recording window cannot receive the click event when the teacher clicks the button control, so that the teacher cannot operate courseware, and therefore the click event needs to be captured and handed to the next recording window to respond.
