< method examples >
FIG. 2 is a flow diagram of a method for presenting multi-display content in accordance with an embodiment of the present invention.
As shown in fig. 2, the method of an embodiment of the present invention may include the following steps:
step S2010, providing a preview window.
In an example of the present invention, a form creating function provided by the operating system may be called at step S2010 to provide a preview form for previewing the display contents of all displays.
In an example of the present invention, the step S2010 of providing a preview window may further include the following steps:
step S2011, providing a floating icon for calling out the preview window according to the opening operation, wherein the floating icon moves to the current display where the mouse pointer is located along with the mouse pointer.
According to the step S2011, in the extended mode, the plurality of displays 1030 are equivalent to splicing the display screens of the plurality of displays into a larger display screen to display the content configured and displayed by the processor 1020, and the mouse pointer stays on the display screen of one display according to the user operation, so that the user can move the floating icon to the display observed at the current viewing angle by moving the mouse, and further can call out the preview window through the floating icon without changing the current viewing angle.
In this example, providing the floating icon to move along with the mouse pointer may be performed by obtaining a current actual position of the mouse pointer, and moving the floating icon to a current display on which the mouse pointer is located or to the current actual position on which the mouse pointer is located according to the current actual position.
Step S2012, a preview form is provided on the display where the floating icon is located.
According to the step S2012, after the method of the embodiment of the present invention is started by the floating icon, a preview form is provided on the display where the floating icon is located.
After the preview window is provided, the user can drag the preview window by a mouse to move the preview window to other displays for displaying.
In step S2020, the display content of each display is captured.
According to this step S2020, the display content is a display screen on the display screen.
In one example of the invention, a screen capture function provided by the operating system may be invoked to capture the display content of each display.
In one example of the present invention, a screen capture tool provided by third-party software may be invoked to capture the display content of each display.
And step S2030, splicing and displaying the captured display content of each display in a preview window.
In an example of the present invention, the step S2030 splicing and displaying the captured display content of each display in the preview window may further include:
and S2031, splicing the captured display contents of each display into a picture.
In a further example of the present invention, the step S2031 of stitching the captured display content of each display into a picture may include the following steps:
step S2031a, acquiring resolutions and arrangements of the plurality of displays.
In an example of the present invention, after the method according to the embodiment of the present invention is started, the resolutions and the arrangement structures of the plurality of displays may be obtained according to the system setting and stored in the designated location, so that the resolutions and the arrangement structures of the plurality of displays may be directly obtained from the designated location each time the tile is performed, and the response speed is improved.
In one example of the invention, the resolution and arrangement of multiple displays may be obtained by a technician from a system setting when forming the method of the invention, and the data written directly into instructions for performing the method of an embodiment of the invention.
Step S2031b, according to the resolution and the arrangement structure of the plurality of displays, the captured display content of each display is spliced into a picture.
According to this step S2031b, the spliced picture will reflect the actual display effect of the extended display by the plurality of displays.
And step S2032, displaying the picture in a preview window.
In an example of the present invention, the step S2032 of displaying the picture in the preview window may further comprise the steps of:
step S2032a, obtaining the size ratio of the preview window to the picture.
Step S2032b, zooming the picture according to the size ratio to make the zoomed picture consistent with the size of the preview window.
Step S2032c, displaying the zoomed picture in the preview window.
According to the example of the invention, the picture content can be displayed by utilizing the preview window to the maximum extent so as to realize the clearest display.
In an example of the present invention, the capturing of the display content of each display in step S2020 above may further be: and capturing the current display content of each display at intervals of set time according to the timing setting of the timer so as to refresh the display content displayed by the preview window. Thus, the timed refresh of the content displayed in the preview window can be realized through step S2030.
The set time can be set according to the requirements of users, for example, the set time is set to be less than or equal to the time response capability of human eyes, so that the real-time refreshing of the content displayed by the preview window can be realized, and the smooth and unsmooth visual effect can be provided for the users.
For example, if the set time is 1s, the holding time of each frame of picture displayed by the preview window is 1s, the 1 st s displays the first frame of picture obtained by capturing and splicing, the 2 nd s refreshes and displays the second frame of picture obtained by capturing and splicing, the 3 rd s refreshes and displays the third frame of picture obtained by capturing and splicing, and so on.
According to the method provided by the embodiment of the invention, a user can simultaneously observe the display contents of the plurality of displays on any one of the plurality of displays through the preview window, so that the user can conveniently observe and operate the preview window, and particularly, the user experience can be greatly improved under the condition that the user cannot simultaneously observe the display contents of each display due to the arrangement positions of the plurality of displays.

step S3010, after the display content of each display captured in step S2030 is displayed in a preview window in a splicing manner, acquiring a current actual position of the mouse pointer.
The current actual position may be an absolute position coordinate of the mouse pointer or a relative position coordinate of the mouse pointer, where the absolute position coordinate represents a position coordinate of the mouse pointer on a larger display screen obtained by splicing multiple displays, and the relative position coordinate represents a position coordinate of the mouse pointer on the display screen of the display where the mouse pointer is currently located.
And step S3020, determining the current preview position of the mouse pointer in the preview window according to the current actual position.
According to this step S3020, the current actual position of the mouse pointer on the display can be reflected by the current preview position of the mouse pointer on the preview window, i.e. the pixel content of the preview window at the current preview position is the same as the pixel content of the display at the current actual position.
Step S3030, providing a virtual mouse pointer at the current preview position of the preview window.
According to the step S3030, after the content displayed in the preview window is refreshed, the current preview position of the mouse pointer on the preview window is refreshed accordingly, so that the user can know the current actual position of the real mouse pointer by observing the virtual mouse pointer on the preview window, and can accurately complete the required operation by perceiving that the virtual mouse pointer on the preview window is moved, without changing the viewing angle to search for the real mouse pointer.
< example >
