图3示出了根据本发明的一个示范性实施例的一种虚拟屏幕构建方法300的流程示意图。方法300适于在计算设备200中执行。如图3所示,一种虚拟屏幕构建方法300始于步骤S310,屏幕管理模块120设置虚拟屏幕的屏幕参数,并根据屏幕参数构建虚拟屏幕。
屏幕管理模块120在构建虚拟屏幕之前,首先根据通信接口确定计算设备是否连接有物理屏幕。在当计算设备连接有物理屏幕时,则优先使用物理屏幕进行显示,可不必进行构建虚拟屏幕。若确定计算设备连接有物理屏幕,则屏幕管理模块120将模式选项设置为物理屏幕。屏幕管理模块120的模式选项包括物理屏幕和虚拟屏幕。接着屏幕管理模块120获取物理屏幕的屏幕参数,并根据窗口管理模块110构建的显示窗口,在物理屏幕中绘制显示窗口。物理屏幕和虚拟屏幕的屏幕参数项目相同,但屏幕管理模块120在构建虚拟屏幕时,可以根据需要设置与物理屏幕不同参数,同时设置的参数数值也更加灵活,便于满足显示任务的多种需求。
根据本发明的一个实施例,当计算设备连接有物理屏幕时,窗口管理模块110构建应用的显示窗口以便在物理屏幕中进行显示。构建的多个显示窗口通过验证(Validate)接口发送到与所连接的物理设备相应的驱动程序中进行处理。驱动程序可同时处理一定数量的显示窗口,当所接收到的显示窗口的数目大于处理能力时,指示窗口管理模块110将这些显示窗口添加物理屏幕的标签一并发送至屏幕管理模块120,以便屏幕管理模块120通过识别到物理屏幕的标签,对这些显示窗口进行处理,先合并为一个显示窗口再通过提交(Present)接口发送给驱动程序进行处理。
根据本发明一个示范性实施例,当计算设备连接有物理屏幕时,窗口管理模块110构建有5个显示窗口。与计算设备所连接的物理屏幕相应的驱动程序的处理能力为3个显示窗口,即驱动程序可同时处理3个显示窗口。此时窗口管理模块110通过验证(Validate)接口将这5个显示窗口发送到驱动程序后,驱动程序指示窗口管理模块110为这个显示窗口添加物理屏幕的标签,发送到屏幕管理模块120,以便屏幕管理模块120通过识别到物理屏幕的标签将这些显示窗口合并为一个显示窗口再通过提交(Present)接口发送至驱动程序进行处理。
若计算设备未连接有物理屏幕,则屏幕管理模块120将模式选项设置为虚拟屏幕。图像显示系统100中还包括有电源管理模块130。随后,屏幕管理模块 120查看电源管理模块130是否接收到用户的关闭虚拟屏幕的虚拟屏幕控制指令,若未接收到相应的控制虚拟屏幕关闭的控制指令,则设置虚拟屏幕的屏幕参数。
屏幕参数包括功能参数、标识参数、类型参数和配置参数。配置参数中包括虚拟屏幕的高度、宽度和刷新频率。根据本发明的一个实施例,屏幕管理模块120所建立的一个虚拟屏幕的功能参数中,开关状态为开启,缩放参数为支持缩放;显示屏标识为screen1,制造商信息为tx;类型参数为VGA;配置参数如下所示:
Figure PCTCN2021124289-appb-000002
接着,屏幕管理模块120按照上述参数构建虚拟屏幕:根据虚拟屏幕的宽度,和高度构建虚拟屏幕的大小,根据刷新频率确定虚拟屏幕绘制显示窗口的频率。
随后,执行步骤S320,窗口管理模块110为运行的每个应用构建显示窗口,得到多个显示窗口。窗口管理模块110根据应用的运行状态确定显示窗口。应用的运行状态可以从计算设备中运行的操作系统中获得。随后,由于计算设备不连接有物理屏幕,因此没有对应的驱动程序对显示窗口进行处理。因此当窗口管 理模块110需要通过Validate接口将显示窗口发送到驱动程序时,窗口管理模块110直接为显示窗口添加虚拟屏幕的标签,以便窗口管理模块110对显示窗口进行绘制。
随后,执行步骤S330,屏幕管理模块120将构建的多个显示窗口在虚拟屏幕中进行绘制,以便计算设备继续运行应用。屏幕管理模块120获取显示窗口并对其标签进行识别,若识别标签的结果为虚拟屏幕,则对这些显示窗口进行处理和渲染工作,不再通过Present接口发送至驱动程序,直接在虚拟屏幕中进行显示。这样计算设备即可顺利完成图像处理及显示相关工作,当需要了解应用执行图像相关任务的运行状态时,可以通过截屏操作来查看图像渲染和显示结果。
计算设备中包括有存储器,存储器可实现为计算设备中包括的显卡的存储器,用作虚拟显示内存。计算设备还包括有图像数据管理器,用于分配显示内存,如从显示内存中分离出一个内存块,以便屏幕管理模块在该内存块中进行显示窗口的绘制操作后,存储相应的显示信息。
屏幕管理模块对显示窗口在虚拟屏幕中进行绘制包括步骤:从计算设备的存储器获取由图像数据管理器分配的内存块,将内存块与虚拟屏幕进行关联操作,以便让虚拟屏幕将该内存块中的显示窗口进行显示。接着在进行关联操作后的内存块中进行显示窗口的绘制操作,执行对应显示窗口的绘制语句,完成显示窗口的绘制,本发明对显示窗口的绘制语句的具体内容不作限制,本领域技术人员可根据需要的绘制方法构建绘制语句实现显示窗口的绘制。最后屏幕管理模块将虚拟屏幕所关联的所有内存块中绘制的显示窗口进行合并,得到虚拟屏幕的内存块,虚拟屏幕的内容块中存储有当前虚拟屏幕绘制的所有显示窗口。由于虚拟屏幕与物理屏幕相同,在显示应用的显示窗口时,只能从一个内存块中读显示信息,因此,需要提前对多个显示窗口的内存块进行处理,合并为一个虚拟屏幕的内存块,以便虚拟屏幕对内存块中的所有显示窗口同时进行显示。
根据本发明的一个实施例,当屏幕管理模块构建虚拟屏幕并在其中绘制显示窗口时,屏幕管理模块接收来自用户的截屏指令,截屏指令指示屏幕管理模块 对当前虚拟屏幕所显示的内容进行截屏操作,以便用户查看当前系统及应用运行状态。随后,屏幕管理模块根据截屏指令,从虚拟屏幕的内存块中获取所存储的显示信息,显示信息包括当前虚拟屏幕绘制的所有显示窗口,并将显示信息以截屏图片的形式进行保存,将截屏图片在存储器中进行存储,以便用户进行查看。
根据本发明的一个实施例,当屏幕管理模块120构建虚拟屏幕并在其中绘制显示窗口时,电源管理模块130接收来自用户的虚拟屏幕控制指令。用户可以通过计算设备所连接的输入设备等发送虚拟屏幕控制指令,以控制虚拟屏幕开启和关闭。
虚拟屏幕控制指令包括关闭虚拟屏幕和开启虚拟屏幕,电源管理模块130根据虚拟屏幕控制指令关闭或开启虚拟屏幕。当电源管理模块130接收到关闭虚拟屏幕的控制指令时,控制屏幕管理模块120将功能参数中的开关状态修改为关闭,即可实现关闭虚拟屏幕;当电源管理模块130接收到开启虚拟屏幕的控制指令时,控制屏幕管理模块120将功能参数中的开关状态从关闭修改为开启,即可实现开启虚拟屏幕。
根据本发明的一个实施例,电源管理模块130还监测适于连接物理屏幕的通信接口,当监测到计算设备通过通信接口连接有物理屏幕时,将虚拟屏幕所绘制的显示窗口转移到物理屏幕中进行显示。从而能够在计算设备使用虚拟屏幕进行显示过程中,接入了物理屏幕后能够及时切换到物理屏幕显示,进行显示屏幕的无缝切换,提高对物理屏幕和虚拟屏幕的适用性。与此同时,及时将虚拟屏幕释放,节约计算机资源,提高系统和应用运行效率。
本发明中的一种虚拟屏幕构建方法适于在计算设备中执行。计算设备中运行有图像显示系统和多个应用,图像显示系统包括窗口管理模块和屏幕管理模块。屏幕管理模块通过设置虚拟屏幕的屏幕参数,根据屏幕参数构建虚拟屏幕,便于计算机在虚拟屏幕中绘制并显示应用的显示窗口,无阻碍的继续运行。
并进一步的,本发明中在构建虚拟屏幕前,对计算机是否连接有物理屏幕进行检测,若检测到连接了物理屏幕,则可在物理屏幕中绘制显示应用的显示窗口。 图像显示系统中还包括电源管理模块,在使用虚拟屏幕进行显示的过程中,电源管理模块通过计算机的通信接口监测到连接有物理屏幕时,将虚拟屏幕绘制的显示窗口转移到物理屏幕中进行显示,从而能够实现兼容物理屏幕和虚拟屏幕,和二者之间的智能切换。电源管理模块还接收用户的虚拟屏幕控制指令,虚拟屏幕控制指令包括关闭虚拟屏幕和开启虚拟屏幕,从而电源管理模块根据用户的需要对虚拟屏幕的关闭或开启进行控制。
