Embodiment 1

[0031] 1. The user opens multiple non-overlapping windows successively on the splicing wall, and the window information management module records the coordinate information, window size and Z-order information of the windows on the wall. The window coordinate information and window size information include window starting coordinates (x, y) and window width and height values. Window label implementation module, when opening a window, create a label label signal window title at a specific position of the window on the operation interface, such as figure 1 Three non-overlapping windows are opened (Zhongshan, Shenzhen, and Foshan windows), and the title is displayed in the upper left corner of the window:

[0032] 2. The user opens a new window on the basis of step 1, and the window completely covers some of the original windows on the wall. The window information management module records information such as the coordinates of the newly opened window, the width and height of th...

Embodiment 2

[0038] 1. On the basis of Example 1, the user can learn that there are two windows covered under the window labeled "Guangzhou". When the user clicks on the "Shenzhen" label, the window switching module notifies the video wall processor to display the "Shenzhen" window on top, and on the other hand notifies the window label implementation module to modify the status of the existing label.

[0039] 2. The window label implementation module rewrites the existing label layout after receiving the instruction from step 1, that is, deletes the "Shenzhen" label on the original label column, such as image 3 Shown:

[0040] The final display effect of this embodiment is that the "Shenzhen" window completely covered by the "Guangzhou" window is superimposed on the other two windows because it is displayed on top again, but the other two windows are not completely covered due to the relationship between the window size and coordinates . At the same time, the "Foshan" window, which was...

Abstract

The invention discloses a method and a system for switching of superposed windows of a joined screen to realize window switching in complete window coverage. The method includes: 1) recording coordinate information and Z-order information of all windows on the joined screen; 2) judging whether window superposition exists or not and whether other windows are completely covered or not, when other windows are completely or partially covered, acquiring information of a top-layer window and the windows covered by the top-layer window, starting a step 3), and otherwise, starting the step 1); 3) setting a plurality of new tags on the top-layer window according to the acquired information, wherein the quantity of the tags is equal to amount of the top-layer window and the windows covered by the top-layer window, each tag describes attributes of one window, and window switching is realized by the tag of the top-layer window. The tags are set for the top-layer window in the superposed windows and other windows covered by the top-layer window for recognition, and switch display among the plurality of superposed windows is realized by operating the tags.

Description

technical field [0001] The present invention relates to the field of splicing walls, and more specifically, to a method and system for switching superimposed windows of a splicing wall. Through this method, the signal windows of various channels superimposed on the splicing wall can be intuitively identified, and the fast switching of any superimposed windows can be realized. Show on top. Background technique [0002] At present, the splicing wall system has been applied to many system fields including transportation, electric power, security and so on. Putting various application software and monitoring video images on the splicing wall greatly facilitates people's monitoring of various data, and provides the possibility for data analysis and rapid resource allocation. [0003] In general, users can open windows of any size on the splicing screen, and multiple windows can be superimposed and displayed at the same time. If multiple signal windows are opened successively in...
