图1为一实施例中应用窗口预览方法的示意性流程图，如图1所示，所述方法的步骤包括：FIG. 1 is a schematic flowchart of a method for previewing an application window in an embodiment. As shown in FIG. 1 , the steps of the method include:
S101，接收预览终端发送的窗口预览指令，根据所述窗口预览指令开启对应应用窗口并设置所述应用窗口的属性为大屏显示终端不可见。S101: Receive a window preview instruction sent by a preview terminal, open a corresponding application window according to the window preview instruction, and set an attribute of the application window to be invisible to the large-screen display terminal.
在本步骤中，预览终端可以是电脑、平板以及智能手机等，预览终端中预先安装了预览软件，可以通过预览软件发出窗口预览指令。另外，本实施例的应用环境也可以是电脑、平板等智能终端，应用窗口可以是智能终端中运行应用程序的应用窗口。In this step, the preview terminal can be a computer, a tablet, a smart phone, etc., and preview software is pre-installed in the preview terminal, and a window preview instruction can be issued through the preview software. In addition, the application environment of this embodiment may also be an intelligent terminal such as a computer and a tablet, and the application window may be an application window for running an application program in the intelligent terminal.
S102，获取所述应用窗口当前显示的数据作为待预览数据，将所述待预览数据发送至预览终端进行预览。S102: Acquire data currently displayed in the application window as data to be previewed, and send the data to be previewed to a preview terminal for previewing.
在本步骤中，在开启对应应用窗口之后，信号源的数据可以在应用窗口中显示，此时，获取应用窗口中显示的待预览数据，然后将获取的待预览数据发送至预览终端中进行预览。In this step, after the corresponding application window is opened, the data of the signal source can be displayed in the application window. At this time, the data to be previewed displayed in the application window is obtained, and then the obtained data to be previewed is sent to the preview terminal for preview. .
本实施例中，通过接收预览终端发送的窗口预览指令，然后对应开启需要预览的应用窗口，并立即设置应用窗口的属性为大屏显示终端不可见，此时，大屏显示终端中不会显示该应用窗口，读取应用窗口当前显示的待预览数据，将待预览数据实时发送至预览终端中进行预览。通过将应用窗口的属性设置为大屏显示终端不可见，从而实现屏显示应用窗口中的信号进行预览。In this embodiment, the window preview command sent by the preview terminal is received, and then the application window to be previewed is opened correspondingly, and the attribute of the application window is immediately set to be invisible to the large-screen display terminal. At this time, the large-screen display terminal will not display the The application window reads the data to be previewed currently displayed in the application window, and sends the data to be previewed to the preview terminal in real time for preview. By setting the properties of the application window to be invisible to the large-screen display terminal, the signals in the application window can be displayed on the screen for preview.
对于S101的步骤，在一实施例中，预览指令包括对应应用窗口类型的开窗信息，应用窗口的类型包括一类应用窗口以及二类应用窗口；其中，所述一类应用窗口为操作系统自身的应用窗口，所述二类应用窗口为软件创建的应用窗口；可以通过以下方式根据所述窗口预览指令开启对应应用窗口：解析所述开窗信息，根据所述开窗信息开启所述一类应用窗口，或根据所述开窗信息创建所述二类应用窗口。For the step of S101, in one embodiment, the preview instruction includes windowing information corresponding to the type of the application window, and the type of the application window includes a first-class application window and a second-class application window; wherein, the first-class application window is the operating system itself The application window of the second type of application window is an application window created by software; the corresponding application window can be opened according to the window preview instruction in the following ways: parsing the windowing information, and opening the first-class application window according to the windowing information application window, or create the second-type application window according to the windowing information.
在本实施例中，根据预览终端发送的开窗信息，可以开启对应的应用窗口，例如，操作系统可以是Windows系统，预览终端预览的是PPT格式文件，那么，根据开窗信息可以开启操作系统的Microsoft PowerPoint软件，如果信号源数据需要用软件创建的应用窗口显示，那么在接收到开窗信息之后，需要对应创建二类应用窗口。In this embodiment, according to the window opening information sent by the preview terminal, a corresponding application window can be opened. For example, the operating system can be a Windows system, and the preview terminal previews a PPT format file. Then, the operating system can be opened according to the window opening information. Microsoft PowerPoint software, if the signal source data needs to be displayed in the application window created by the software, after receiving the windowing information, it is necessary to create a corresponding application window of the second type.
可选的，还可以通过以下方式根据所述窗口预览指令开启对应应用窗口并设置所述应用窗口的属性为大屏显示终端不可见：根据所述窗口预览指令，若所述应用窗口为一类应用窗口，平移应用窗口在大屏显示终端的显示位置，使得所述应用窗口落入大屏显示终端的非显示区域；若所述应用窗口为二类应用窗口，则设置应用窗口的窗口属性为隐藏；或，在大屏显示终端非显示区域创建所述二类应用窗口。Optionally, the corresponding application window can also be opened according to the window preview instruction and the attribute of the application window is set to be invisible to the large-screen display terminal in the following manner: according to the window preview instruction, if the application window is a class Application window, translate the display position of the application window on the large-screen display terminal, so that the application window falls into the non-display area of the large-screen display terminal; if the application window is a second-class application window, set the window attribute of the application window as hide; or, create the second type of application window in the non-display area of the large-screen display terminal.
在本实施例中，由于一类应用窗口为操作系统自身的应用窗口，窗口特性复杂，设置一类应用窗口的窗口属性为隐藏可能不能完全隐藏该应用窗口中，二类应用窗口为软件自身创建的应用窗口，可以自定义该应用窗口的特性，因此，在设置所述应用窗口的属性为大屏显示终端不可见，只需将二类应用窗口的窗口属性设置为隐藏，即可以实现在大屏显示终端不可见。In this embodiment, since the first-class application window is the application window of the operating system itself, and the window characteristics are complex, setting the window attribute of the first-class application window as hidden may not completely hide the application window, and the second-class application window is created by the software itself The application window can customize the characteristics of the application window. Therefore, after setting the attribute of the application window to be invisible to the large-screen display terminal, it is only necessary to set the window attribute of the second-type application window to hide, and then the large-screen display terminal can be set to be hidden. The on-screen display terminal is not visible.
另外，在开窗时，还设置了开窗的坐标信息，例如大屏显示端的显示坐标为X轴坐标为正的区域，为了让应用窗口中的内容在大屏显示终端显示，应用窗口应该也开在大屏显示端的显示坐标内。In addition, when opening the window, the coordinate information of the window is also set. For example, the display coordinates of the large-screen display end are the area where the X-axis coordinate is positive. In order to display the content in the application window on the large-screen display terminal, the application window should also be Open in the display coordinates of the large screen display end.
对于一类应用窗口，由于是操作系统自身的应用窗口，在开启一类应用窗口的同时，获取一类应用窗口的应用窗口句柄，然后立即将一类应用窗口移动到大屏显示终端显示坐标之外，例如X轴坐标为负的区域，这样，一类应用窗口中显示的内容就不会显示在大屏显示终端上。For a type of application window, since it is the application window of the operating system itself, when a type of application window is opened, the application window handle of the type of application window is obtained, and then the type of application window is immediately moved to the display coordinates of the large-screen display terminal. In addition, for example, the area where the X-axis coordinate is negative, in this way, the content displayed in a type of application window will not be displayed on the large-screen display terminal.
对于二类应用窗口，由于是软件创建的应用窗口，有两种方式设置所述应用窗口的属性为大屏显示终端不可见，其一是通过将二类应用窗口的窗口属性设置为隐藏，那么在大屏显示终端上也不会显示信号源数据，其二是直接在X轴坐标为负的区域内创建二类应用窗口，那么二类应用窗口中显示的待预览数据也不会在大屏显示终端上显示。For the second-class application window, because it is an application window created by software, there are two ways to set the attribute of the application window to be invisible to the large-screen display terminal. One is to set the window attribute of the second-class application window to hidden, then The signal source data will not be displayed on the large-screen display terminal. The second is to directly create a second-class application window in the area where the X-axis coordinate is negative, so the data to be previewed displayed in the second-class application window will not be displayed on the large screen. displayed on the display terminal.
在一实施例中，在根据所述窗口预览指令开启对应应用窗口之后，还需要获取所述应用窗口的窗口句柄，获取应用窗口的窗口句柄之后，可以根据所述窗口句柄，获取当前应用窗口中显示的待预览数据。In one embodiment, after the corresponding application window is opened according to the window preview instruction, the window handle of the application window needs to be obtained. After obtaining the window handle of the application window, the current application window can be obtained according to the window handle. Displayed data to be previewed.
在本实施例中，根据窗口句柄可以获取到应用窗口当前显示的图像数据，然后将图像数据实时发送至预览终端，预览终端中可以看到应用窗口中的实时图像数据，从而实现对应用窗口中的图像数据进行预览。In this embodiment, the image data currently displayed in the application window can be obtained according to the window handle, and then the image data is sent to the preview terminal in real time, and the real-time image data in the application window can be seen in the preview terminal. preview the image data.
可选的，在将图像数据实时发送至预览终端之前，还需要将图像数据进行编码，另外，需要和预览终端通过特定的通讯协议，将编码后的图像数据发送预览终端。Optionally, before sending the image data to the preview terminal in real time, the image data also needs to be encoded. In addition, the encoded image data needs to be sent to the preview terminal through a specific communication protocol with the preview terminal.
在一些实施例中，还提供一种应用窗口预览方法，图2为另一实施例中应用窗口预览方法的示意性流程图，如图2所示，所述方法的步骤包括：In some embodiments, a method for previewing an application window is also provided. FIG. 2 is a schematic flowchart of a method for previewing an application window in another embodiment. As shown in FIG. 2 , the steps of the method include:
S201，向服务终端发送窗口预览指令；其中，所述窗口预览指令是用于触发服务终端开启对应应用窗口并设置所述应用窗口的属性为大屏显示终端不可见的；S201, sending a window preview instruction to a service terminal; wherein, the window preview instruction is used to trigger the service terminal to open a corresponding application window and set the attribute of the application window to be invisible to the large-screen display terminal;
在本步骤中，服务终端可以是电脑、平板以及智能手机等，预览终端中预先安装了服务软件，可以通过服务软件处理窗口预览指令。另外，本实施例的应用环境也可以是电脑、平板等智能终端。In this step, the service terminal may be a computer, a tablet, a smart phone, etc., the preview terminal is pre-installed with service software, and the window preview instruction can be processed through the service software. In addition, the application environment of this embodiment may also be an intelligent terminal such as a computer and a tablet.
S202，接收所述服务终端发送的待预览数据，所述待预览数据为所述应用窗口中实时显示的数据。S202: Receive data to be previewed sent by the service terminal, where the data to be previewed is data displayed in real time in the application window.
在本步骤中，服务终端中对应开启应用窗口之后，服务终端中信号源数据将显示在应用窗口中，服务软件可以获取应用窗口中的待预览数据。In this step, after the corresponding application window is opened in the service terminal, the signal source data in the service terminal will be displayed in the application window, and the service software can obtain the data to be previewed in the application window.
S203，对所述待预览数据进行显示。S203: Display the data to be previewed.
在本步骤中，可以通过预览软件实时预览待预览数据。In this step, the data to be previewed can be previewed in real time through the preview software.
本实施例中，通过对服务终端下发窗口预览指令，服务终端根据窗口预览指令开启对应的应用窗口，并设置应用窗口的属性为大屏终端不可见，此时，大屏显示终端中不会显示该应用窗口，接收应用窗口当前显示的待预览数据，然后对待预览数据进行预览。通过将应用窗口的属性设置为大屏显示终端不可见，从而实现对应用应用窗口进行预览。In this embodiment, by issuing a window preview instruction to the service terminal, the service terminal opens the corresponding application window according to the window preview instruction, and sets the attribute of the application window to be invisible to the large-screen terminal. At this time, the large-screen display terminal does not The application window is displayed, the data to be previewed currently displayed in the application window is received, and then the data to be previewed is previewed. By setting the properties of the application window to be invisible on the large-screen display terminal, the application window can be previewed.
对于S201的步骤，在一实施例中，应用窗口预览指令中包括了对应应用窗口类型的开窗信息，服务终端中的服务软件根据开窗信息，开启对应的应用窗口，应用窗口的类型包括：一类应用窗口和二类应用窗口，其中，所述一类应用窗口为操作系统自身的应用窗口，所述二类应用窗口为软件创建的应用窗口；服务软件通过解析开窗信息，如果开启的应用窗口为一类应用窗口，则对应开启操作系统自身的应用窗口即可，如果开启的应用窗口是二类应用窗口，则需要由服务软件新建应用窗口。For the step of S201, in one embodiment, the application window preview instruction includes windowing information corresponding to the application window type, and the service software in the service terminal opens the corresponding application window according to the windowing information, and the type of the application window includes: A first-class application window and a second-class application window, wherein the first-class application window is an application window of the operating system itself, and the second-class application window is an application window created by software; If the application window is a first-class application window, the corresponding application window of the operating system can be opened. If the opened application window is a second-class application window, the service software needs to create a new application window.
可选的，服务软件还可以通过以下方式根据所述应用窗口预览指令开启对应应用窗口并设置所述应用窗口的属性为大屏显示终端不可见：若所述应用窗口为一类应用窗口，平移所述应用窗口在大屏显示终端的显示位置，使得所述应用窗口落入大屏显示终端的非显示区域；若所述应用窗口为二类应用窗口，则设置所述应用窗口的应用窗口属性为隐藏；或，在大屏显示终端非显示区域创建所述二类应用窗口。Optionally, the service software can also open the corresponding application window according to the application window preview instruction and set the attribute of the application window to be invisible to the large-screen display terminal in the following manner: if the application window is a first-class application window, panning The display position of the application window on the large-screen display terminal, so that the application window falls into the non-display area of the large-screen display terminal; if the application window is a second-class application window, the application window attribute of the application window is set To hide; or, create the second type of application window in the non-display area of the large-screen display terminal.
在本实施例中，由于一类应用窗口为操作系统自身的应用窗口，窗口特性复杂，设置一类应用窗口的应用窗口属性为隐藏可能不能完全隐藏应用窗口中显示的待预览数据，二类应用窗口为软件创建的应用窗口，应用窗口结构简单，因此，在设置所述应用窗口的属性为大屏显示终端不可见，只需将二类应用窗口的应用窗口属性设置为隐藏，即可以实现在大屏显示终端不可见。In this embodiment, since the first-class application window is the application window of the operating system itself, and the window characteristics are complex, setting the application window attribute of the first-class application window to hide may not completely hide the to-be-previewed data displayed in the application window. The window is an application window created by software, and the structure of the application window is simple. Therefore, when the attribute of the application window is set to be invisible to the large-screen display terminal, it is only necessary to set the application window attribute of the second type of application window to be hidden. The large screen display terminal is not visible.
另外，服务软件在开窗时，还设置了开窗的坐标信息，例如大屏显示端的显示坐标为X轴坐标为正的区域，为了让应用窗口中的内容在大屏显示终端显示，应用窗口应该也开在大屏显示端的显示坐标内。In addition, when the service software opens the window, it also sets the coordinate information for opening the window. For example, the display coordinates of the large-screen display end are the area where the X-axis coordinate is positive. In order to display the content in the application window on the large-screen display terminal, the application window It should also be opened in the display coordinates of the large screen display end.
对于一类应用窗口，由于是操作系统自身的应用窗口，在开启一类应用窗口的同时，获取一类应用窗口的应用窗口句柄，然后立即将一类应用窗口移动到大屏显示终端显示坐标之外，例如X轴坐标为负的区域，这样，一类应用窗口中显示的内容就不会显示在大屏显示终端上。For a type of application window, since it is the application window of the operating system itself, when a type of application window is opened, the application window handle of the type of application window is obtained, and then the type of application window is immediately moved to the display coordinates of the large-screen display terminal.
