Problems solved by technology

During use, if a particularly large document is loaded, such as the document uses a particularly complex template, and the slideshow contains complex ole objects, pictures, animations, sound elements, slideshow transitions, and complex custom animations, etc., or is affected by the platform, it is bound to The document loads slowly, and the user waits for a long time, which affects the user experience

specific Embodiment approach

[0025] figure 2 A general flowchart of the improved method for presentation document loading is presented. The specific implementation mode that the present invention adopts is as follows:

[0026] (1) Import the document first (step S1);

[0027] (2) Judging the document, and comparing it with the presentation filter to determine whether it is a document corresponding to the presentation (step S2);

[0028] (3) If it is a presentation document, open up a new thread (step S3), the main way to open the thread is as follows: OpenOffice creates multi-threaded functions for different platforms and repackages them, which are defined in the class osl::Thread , before loading the presentation document, by inheriting the above class, using the virtual function void run() of this class to throw a child thread, while creating the child thread, it is actually for each thread in TLS (Thread Local Storage) create their own global variables and occupy memory blocks to prevent data excep...

Abstract

The invention discloses a method for asynchronously loading power point documents, which is a thread management method for loading the power point documents by using an impress component in OpenOffice. The method comprises the following steps of: 1, introducing a document; 2, judging the document, contrasting through a power point filter and judging whether the document is a corresponding power point document; 3, if the document is the power point document, developing a new document resolving sub thread; and 4, after the document resolving sub thread resolves a document template, controlling to make a master thread execute continuously through a function so as to build and display a power point module view framework, and controlling the continuous interaction between the master thread for the view displaying and the resolving sub thread. When a large power point document is uploaded, a remarkable effect is achieved.

Description

technical field [0001] The invention relates to the field of document processing, in particular to a method for asynchronously loading presentation documents. Background technique [0002] In people's daily study and work, it is often necessary to open and browse presentation documents and play slide shows. Presentation is a cross-platform office software suite, and the impress component in OpenOffice can be used to make and play slide shows. At present, the main method of opening a presentation document is as follows: firstly, the document is loaded and analyzed, and the current loading progress is displayed through the progress bar; secondly, after the document is loaded, the corresponding view frame is established and the view display of the document content is performed. During use, if a particularly large document is loaded, such as the document uses a particularly complex template, and the slideshow contains complex ole objects, pictures, animations, sound elements, sl...
