Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1:
as shown in fig. 1, embodiment 1 of the present invention provides a PPT showing control method for a college online education system, including:
s11, receiving an instruction sent by a user to simultaneously display a plurality of PPT files, opening a plurality of corresponding PPT files and automatically entering a display state, wherein each time one PPT file is opened, a PPT display thread is correspondingly established, and a display interface of one PPT file is displayed on a display screen;
specifically, a user selects a plurality of PPT files to be displayed simultaneously or sequentially through a click or touch event, after the system receives a request of the user for displaying the PPT files, the system opens the PPT files by using corresponding software and loads the PPT files to a display state, preferably opens the PPT files by using a COM component, the COM component comprises the display components of the PPT files in a plurality of formats, such as formats corresponding to the PPT files manufactured by OFFICE or WPS in all current versions, and after the COM component receives the request for opening the PPT files, the corresponding display component is selected to open the PPT files and display according to the formats of the PPT files to be opened, so that the PPT files in the plurality of formats can be compatible simultaneously.
When a PPT file is opened, a PPT projection thread is correspondingly established, so that multiple PPT files can be simultaneously in a projection state, but only a projection interface of one PPT file can be simultaneously displayed on a display screen.
S12, when an instruction of switching to a projection interface of the next PPT file sent by a user is received, switching a corresponding PPT projection thread to display, and displaying the projection interface of the PPT file selected by the user on a display screen;
specifically, a user clicks a button on a screen or selects a PPT file displayed on the display screen through a remote controller, after receiving a request for switching a PPT file display interface, the system switches to a PPT display thread corresponding to the PPT file for display according to the PPT file selected by the user, and displays a display interface of the corresponding PPT file on the display screen.
The PPT projection control method for the co-school network teaching system provided by the embodiment of the invention can directly load a plurality of PPT files and automatically enter the projection state, can switch to the projection interface of the next PPT file by one key under the condition of not exiting the PPT file currently being projected, does not influence the projection states of other PPT files on all operations of the currently displayed PPT file, can switch back to the states of other PPT files currently projected when the currently displayed file is operated, can switch the explanation at will when two or more PPT files are simultaneously projected, and can retain all multimedia elements and animation effects in the PPT files.
In one embodiment, each time a PPT file is opened, the PPT file is bound with a page number, the page numbers of the PPT files are arranged in a certain sequence, a user sends an instruction to switch to a display interface of a next PPT file through a page turning function button, and after receiving the instruction, the system switches to a PPT display thread of the next PPT file according to the page number for display. In other embodiments, the page number of the PPT file to be displayed can be directly selected through the number buttons, so that when more than two PPT files are displayed, the display interface of the PPT file to be displayed can be switched by one key, and the operation is more convenient.
Further, when switching to the display interface of the next PPT file, the operation on the PPT file is bound with the currently displayed PPT file, and the previous PPT file retains the previous display state. Namely, the operations of turning pages or stopping showing, etc. only act on the currently displayed PPT file, and other PPT files being shown are not affected.
Example 2:
as shown in fig. 2, embodiment 2 of the present invention provides a PPT showing control method for a college online education system, which is implemented on the basis of embodiment 1, and therefore, repeated details are not repeated:
the method is based on the method of the embodiment 1, and further comprises the following steps: the display interface of the PPT file is displayed through the electronic whiteboard, and the PPT file is edited by writing on the whiteboard page by hand, displaying shooting operation, inserting pictures, inserting audio and video files and playing in the process of displaying the PPT file, so that the PPT file can be edited by writing, inserting multimedia elements and the like without returning to the editing state of the PPT file, and a teacher can conveniently explain the PPT content. The editing operation is only visual, is convenient for teaching, and does not change the content of the original PPT file or the format of the original PPT file.
Further preferably, each page of the PPT file is independently bound to a whiteboard page, the content written on the whiteboard page and the inserted multimedia elements are fused with the content of the current PPT page, when the PPT file is turned up and down, the content of the current page of the PPT file is synchronously displayed with the content of the corresponding whiteboard page, so that the previously opened PPT page can be switched back at any time and the previously edited content can be viewed, and the previous operation trace disappears until the previous page is returned when the PPT file is turned to a new page.
Further, the method for independently binding each page of the PPT file to a whiteboard page is as follows: and when the PPT pages up and down, the corresponding white board page is taken from the database by key removal of the corresponding key value, and then the content of the current page of the PPT file and the content of the corresponding white board page are synchronously displayed.
