As used in the specification of the present application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
As used in this specification and the appended claims, the term "if" may be interpreted contextually as "when", "upon" or "in response to a determination" or "in response to a detection". Similarly, the phrase "if it is determined" or "if a [ described condition or event ] is detected" may be interpreted contextually to mean "upon determining" or "in response to determining" or "upon detecting [ described condition or event ]" or "in response to detecting [ described condition or event ]".
In particular implementations, the mobile terminals described in embodiments of the present application include, but are not limited to, other portable devices such as mobile phones, laptop computers, or tablet computers having touch sensitive surfaces (e.g., touch screen displays and/or touch pads). It should also be understood that in some embodiments, the devices described above are not portable communication devices, but rather are desktop computers having touch-sensitive surfaces (e.g., touch screen displays and/or touch pads).
In the discussion that follows, a mobile terminal that includes a display and a touch-sensitive surface is described. However, it should be understood that the mobile terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and/or joystick.

Fig. 1 is a flowchart showing an example of a method for updating a material preview window of an electronic whiteboard according to an embodiment of the present application. Regarding the execution subject of the method of the embodiment of the present application, it may be a mobile terminal such as a mobile phone, a computer, etc.
As shown in fig. 1, in step 110, the target material corresponding to the material update request is determined. Here, the target material is used to update the initial material set called for by the electronic whiteboard, and the type of the material update operation may not be limited, and may be, for example, an addition operation, a deletion operation, a switching operation, a refresh (modification) operation, or the like for the material.
In some application scenarios, a user may perform various types of material update operations on the mobile terminal, so as to generate a corresponding material update request.
In step 120, a target material preview picture corresponding to the target material is determined. In an example of the embodiment of the present application, target material does not exist in the initial material set, for example, a user adds material to a mobile terminal newly, and there may also not exist a corresponding material preview picture on the mobile terminal, and at this time, the corresponding material preview picture may be determined by means of picture generation. In another example of the embodiment of the present application, target material exists in the initial material set, for example, the user deletes or modifies the material, and a corresponding material preview picture may exist on the mobile terminal, and at this time, the corresponding material preview picture may be determined by means of a search query.
In step 130, the corresponding preview display component in the preview window is updated based on the target material preview picture. Here, the preview window has a plurality of preview display components, and each preview display component is configured based on a corresponding material preview picture in the material set, for example, each preview display component has a corresponding material preview picture.
In the embodiment of the application, the preview window is configured to have a plurality of preview display components, so that when a material is updated, a preview picture of a corresponding material can be used to update a specific preview display component, that is, the preview window is partially updated, and it is not necessary to update the whole preview window and reload all preview pictures, and the preview efficiency when the material is updated can be greatly improved.
In addition, in the embodiment of the present application, the use or the type of the material may not be limited, and the material may be teaching material, office material, or the like. In some application scenarios, the material may be an attachment (e.g., document, audio, video, etc.), whereby the preview window may be efficiently updated as the attachment on the mobile terminal is updated. In other application scenarios, the material may be content in the attachment (e.g., document page, video progress bar), whereby the preview window may be efficiently updated as the attachment content is updated on the mobile terminal.
It should be noted that the material update operation may be various update operations, such as adding a material, deleting a material, switching a material, refreshing (modifying) a material, and the like, and the mobile terminal may adjust the preview processing procedure accordingly for different material update operations.
Fig. 2 is a flowchart illustrating an example of a method for updating a material preview window of an electronic whiteboard in an application scenario of a newly added material according to an embodiment of the present application.
As shown in fig. 2, in step 210, a first target material corresponding to the material addition request is determined, for example, a user may introduce a new material into the mobile terminal. Here, the target material is used to enrich or be added to the initial set of material for electronic whiteboard calls.
In step 220, a corresponding preview picture of the first target material is generated for the first target material corresponding to the material addition request. It should be understood that various image composition methods may be employed to generate preview pictures of the material, such as thumbnails of the material.
In step 230, a first preview display component configured by the target material preview picture is enabled in the preview window. Illustratively, a new preview display component may be added to the preview window, and the preview picture corresponding to the newly added material is used to configure the new preview display component, so as to implement a new preview effect for the material in the preview window.
Fig. 3 is a flowchart illustrating an example of a method for updating a material preview window of an electronic whiteboard in an application scenario in which a material is deleted according to an embodiment of the present application.
In step 310, the second target material corresponding to the material deletion request is determined, for example, the user may operate on the mobile terminal to select the material to be deleted. Specifically, the mobile terminal needs to delete the target material from the initial material set called for by the electronic whiteboard.
In step 320, a second target material preview picture corresponding to the second target material indicated by the material deletion request is determined in the material preview picture set corresponding to the initial material set.
It should be noted that, when the update operation is not performed and the initial material set needs to be previewed, the mobile terminal may generate corresponding preview pictures for each initial material in the initial material set, so as to determine the corresponding material preview picture set.
In combination with the application scenario, when a user selects a material to be deleted on the mobile terminal, the mobile terminal may collectively retrieve corresponding material preview pictures from the material preview pictures.
In step 330, in the preview window, the second preview display component configured based on the second target material preview picture is disabled. Illustratively, a plurality of preview display components configured by the material preview pictures respectively exist in the preview window, and the preview effect of deleting the material can be realized in the preview window by deactivating or deleting the preview display component corresponding to the material preview pictures.
Fig. 4 is a flowchart illustrating an example of a method for updating a material preview window of an electronic whiteboard in an application scenario in which a current material is switched according to an embodiment of the present application.
As shown in fig. 4, in step 410, the third target material corresponding to the current material switching request is determined, for example, the user may operate on the mobile terminal to jump from the currently browsed first attachment page to the second attachment page and display the second attachment page, where the second attachment page may be the corresponding third target material.
In step 420, a third target material preview picture corresponding to the third target material indicated by the current material switching request is determined in the material preview picture set corresponding to the initial material set. It should be understood that, during the current material switching operation, the material before and after switching may be the material already existing on the mobile terminal.
In step 430, a third preview display component in the preview window for displaying the current material is configured based on the third target material preview picture. Illustratively, a third preview display component for displaying the current material (or the material being browsed by the user) exists in the preview window, and when the user switches the current material, the movement can reconfigure the component by using a preview picture corresponding to the updated material, for example, replace the corresponding preview picture, thereby realizing the switching preview effect for the current material in the preview window, only needing local configuration without global updating, saving system resources, and improving preview updating efficiency.
Fig. 5 is a flowchart illustrating an example of a method for updating a material preview window of an electronic whiteboard in an application scenario in which a material is modified according to an embodiment of the present application.
As shown in fig. 5, in step 510, a fourth target material corresponding to the material modification request is determined, for example, the user may operate on the mobile terminal to modify the corresponding material content in the target material.
In step 520, a fourth target material indicated by the modified material modification request is obtained, and a corresponding fourth target material preview picture is generated according to the modified fourth target material. Illustratively, after the user completes the modification of the material, the mobile terminal may generate a corresponding preview picture through various image synthesis manners. In some embodiments, the material modification process may also be displayed synchronously in the preview window, for example, the modified material may be acquired periodically.
In step 530, a third preview display component for displaying the modified material in the preview window is configured based on the fourth target material preview picture.
Illustratively, a third preview display component for displaying the current material (or the material being browsed by the user) exists in the preview window, and when the user switches the current material, the movement can reconfigure the component by using a preview picture corresponding to the updated material, for example, replace the corresponding preview picture, thereby realizing the switching preview effect for the current material in the preview window, only needing local configuration without global updating, saving system resources, and improving preview updating efficiency.
In some application scenarios, when the mobile terminal runs software for content presentation, the mobile terminal may display a plurality of pages of content, and update preview picture data in the preview window synchronously when the pages change. In the embodiment of the application, the preview window can only be responsible for displaying the preview picture, so that the times of loading and updating the preview picture are reduced, and the display efficiency is improved. Specifically, when a content page is added or deleted, a preview picture is added or deleted in a preview window, when the content page is switched, the preview picture corresponding to the current content page in the preview window is updated, and when the preview window is called, the preview picture corresponding to the current content page in the preview window is updated.
According to the embodiment of the application, when the mobile terminal calls the preview window or executes the preview operation function each time, the mobile terminal only needs to replace the preview picture of the corresponding page when the content page is updated, local updating is achieved, the preview pictures corresponding to all the content pages do not need to be loaded, and time consumption and CPU instantaneous occupancy rate can be effectively reduced.
