Wherein, the full screen window mode may be a display interface of the designated software when the current focus window size of the designated software is the same as the screen size. The full-screen window mode may include a mode of enlarging a window corresponding to the window presentation mode to a full screen, or a full-screen presentation mode.

In some embodiments, each of the window handles of the coordinate pixels of at least two corners of the display corresponds to one application process. For example, window handle WndiD _ LT corresponds to application Process1, window handle WndiD _ LB corresponds to application Process2, window handle WndiD _ RT corresponds to application Process3, and window handle WndiD _ RB corresponds to application Process 4. The specific implementation of determining whether the designated software is in the full-screen window mode according to the window handles of the coordinate pixel points of at least two corners of the display may be as follows:

the method comprises the steps of firstly obtaining the window resolution of window handles of coordinate pixel points of at least two corners of a display.

The screen resolution is the precision of the screen image, and refers to the number of pixels that can be displayed by the display. Since the dots, lines and surfaces on the screen or window are composed of pixels, the more pixels the display can display, the finer the picture, and the more information can be displayed in the same screen or window area.

It should be noted that the window resolution of the window handle for obtaining the coordinate pixel points of at least two corners of the display may be obtained through an application program of the designated software, or may be obtained through other methods, which is not specifically limited in this embodiment of the present application.

In some embodiments, an application specifying software may call a function for obtaining a window resolution to obtain a window resolution of a window handle for coordinate pixel points of at least two corners of a display. The function for obtaining the window resolution may be an existing function or a function customized by a person skilled in the art, and the embodiment of the present application does not specifically limit this function.

In other embodiments, the server may send a request to the designated software to request to obtain window handles for coordinate pixel points of at least two corners of the display; the appointed software can respond to the request, call a function for obtaining the window resolution to obtain the window resolution of the window handle of the coordinate pixel points of at least two corners of the display, and send the obtained window resolution of the window handle to the server, and the server can obtain the resolution of the window handle. Alternatively, in some embodiments, the server may include a function pre-written therein for obtaining the window resolution, and then may directly call the function to obtain the window resolution of the window handle. The function for obtaining the window resolution may be an existing function or a function customized by a person skilled in the art, and the embodiment of the present application does not specifically limit this function.

And when the window resolution ratios of the window handles of the coordinate pixel points of at least two corners of the display are equal to the resolution ratio of the screen and the application process names corresponding to the window handles of the coordinate pixel points of at least two corners of the display are consistent, determining that the designated software is in a full-screen window mode.

It should be noted that, when the window resolution of the window handle of the coordinate pixel point of the corner is equal to the resolution of the screen, the window corresponding to the corner can be considered to be in a full-screen window mode, so that the condition that the window of the designated software is blocked by other windows and is judged to be wrong can be effectively avoided. When the window resolution of the window handle of the coordinate pixel point of at least two corners of the display is equal to the resolution of the screen, it can be indicated that the window corresponding to at least two corners is in a full-screen window mode, at this time, the process names corresponding to at least two corners can be further matched, and when the process names corresponding to at least two corners are consistent, it can be determined that the designated software is in the full-screen window mode. For example, when there are windows corresponding to two corners in the full-screen window mode, the Process name corresponding to the first corner is Process1, and the Process name corresponding to the second corner is Process2, at this time, it may be determined that the Process names corresponding to the first corner and the second corner are the same, and further, it may be determined that the designated software is in the full-screen window mode.

In this embodiment, whether the designated software is in the full-screen window mode may be determined according to the window resolutions of the window handles of the coordinate pixel points of at least two corners of the display, and when the window resolutions of the window handles of the coordinate pixel points of at least two corners of the display are equal to the resolution of the screen and the application process names corresponding to the window handles of the coordinate pixel points of at least two corners of the display are consistent, it may be determined that the designated software is in the full-screen window mode.

And thirdly, when the specified software is determined to be in the full-screen window mode, determining whether the process name corresponding to the full-screen window mode is consistent with the process name corresponding to the preset full-screen demonstration mode.

It should be noted that, when the designated software is in the full-screen window mode, the designated software may not play the shared content, but only enlarge the editable window to the full screen, and at this time, the designated software is still in the window demonstration mode; it is also possible to designate that the software is playing the shared content while the designated software is in a full screen presentation mode. It is further determined whether the process name corresponding to the full screen window mode is consistent with the process name corresponding to the preset full screen presentation mode, so as to determine whether the designated software enters the full screen presentation window.

And finally, when the process name corresponding to the full-screen window mode is consistent with the process name corresponding to the preset full-screen demonstration mode, determining that the designated software enters the full-screen demonstration window.

The process name corresponding to the preset full-screen presentation mode can be a process name corresponding to the designated software in the full-screen presentation mode, and when the process name corresponding to the full-screen window mode is consistent with the process name corresponding to the preset full-screen presentation mode, the designated software can be indicated to play the shared content at the moment, so that the designated software can be determined to enter the full-screen presentation window.

In the embodiment, whether the designated software enters the full-screen demonstration window is determined, window handles of coordinate pixel points of at least two corners of the display can be obtained through the first thread, then whether the designated software is in the full-screen window mode can be determined according to the window handles, then the full-screen window mode is compared with the preset full-screen demonstration mode, and when the full-screen demonstration window mode is consistent with the preset full-screen demonstration mode, the designated software is determined to enter the full-screen demonstration window.

In some embodiments, whether the designated software enters the full-screen presentation window is determined, and the window handle of four coordinate pixel points of the upper left corner, the lower left corner, the upper right corner, the lower right corner and the like of the display can be detected at intervals through the first thread. As shown in fig. 10, the window handles at the corners of the display 4 are different, and the 4 window handles correspond to 4 different application processes, for example, the window handle name at the upper left corner is wndd _ LT, and the application Process name corresponding to the window handle, i.e., program ID1, is Process 1; the window handle name in the lower left corner is WndiD _ LB, and the application Process name corresponding to the window handle, namely program ID2, is Process 2; the name of the window handle at the upper right corner is WndiD _ RT, and the name of the application Process corresponding to the window handle, namely the program ID3 is the Process 3; the window handle name in the bottom right corner is WndiD _ RB, and the application Process name corresponding to the window handle, i.e., program ID4, is Process 4.

If the window resolution of one window handle is equal to the resolution of the screen in the 4 window handles, the application process is considered to be in a full-screen window, so that the condition that the application process is blocked by other windows and is mistakenly judged can be effectively avoided. If 4 window handles, 2 or more than 2 application processes are all in the full-screen window, and the application Process names corresponding to the full-screen window are consistent, for example, the full-screen window appears in the Process1 and the Process2, and the Process1 and the Process2 have the same name, it is determined that the designated software is in the full-screen window mode.

When the designated software is a Word Processing System (WPS), if a process name of the WPS entering a slide full screen window mode is a preset slide process name, for example, WPS.

The second thread can be written into the process of the designated software in advance and used for detecting whether the designated software exits from the full-screen presentation window.

In some embodiments, the specific implementation of detecting whether the specified software exits the full screen presentation window by the second thread may be as follows:

firstly, a handle of a window corresponding to a full-screen demonstration mode is obtained through a second thread.

The second thread may obtain the handle of the window corresponding to the full-screen presentation mode at intervals, and specifically, the second thread may call a function to obtain the handle. The period of time may be set according to actual requirements, for example, the period of time may be 100 milliseconds, which is not specifically limited in the embodiment of the present application. It should be noted that the function may be an existing function or a function customized by a person skilled in the art, and the embodiment of the present application does not specifically limit this.

And secondly, when the handle of the window corresponding to the full-screen demonstration mode is invalid, determining that the designated software exits from the full-screen demonstration window.

It should be noted that, when the window changes, the handle changes accordingly, and is no longer the original handle, so that the handle of the current focus window of the designated software may be matched with the handle of the window corresponding to the full-screen presentation mode, and when the handle of the current focus window of the designated software is not consistent with the handle of the window corresponding to the full-screen presentation mode, the handle of the window corresponding to the full-screen presentation mode may be determined to be invalid, at this time, it may be stated that the window of the designated software has changed, and it may be determined that the designated software exits from the full-screen presentation window.

In this embodiment, the handle of the window corresponding to the full-screen presentation mode may be obtained through the second thread, and whether the handle is valid is determined, and when the handle is invalid, it may be determined that the designated software exits from the full-screen presentation window.
