本发明实施例期望在嵌入式系统上提供一种业务应用窗口能根据需要 确定各自窗口的显示层次关系和窗口切换的方法， 并提供一种多窗口显示 和切换的控制功能装置， 让用户能够通过遥控器动态切换激活系统中存活 的窗口。
本发明实施例为了实现自定义多窗口显示层次并基于遥控器的对窗口 进行切换， 需要图形引擎本身和上层业务应用配合。 所述图形引擎维护一 个当前系统的所有窗口列表， 每个窗口具有一个表征相对位置的窗口属性 值（即业务扩展属性值， 可以用 "xAttr属性值" 表示， 例如业务 Z序）； 设定一个最大的不允许业务应用程序设置的 xAttr属性值（例如， 所述最大 的不允许业务应用程序设置的 xAttr属性值用 "Ztop，， 表示）， 用于把窗口的 用于相对在屏幕下面显示的 xAttr属性值用该 Zt。p ii行临时替换， 当被切到 顶层的目标窗口状态改变时恢复其原来的 xAttr属性值； 上层业务应用窗口 请求显示时， 图形引擎按照当前的窗口列表中的 xAttr属性值决定各窗口的 相对显示层次， 并把按键焦点派发到 xAttr属性值表示相对处于最顶层的、 已经激活获得焦点的窗口上进行处理； 用户按遥控器切换多进程多窗口时， 图形引擎弹出选择窗口列表到顶层， 待用户选中目标后关闭弹出的窗口并 切换到目标窗口上。 所述业务应用根据业务性质和接口参数创建不同类型 的窗口， 默认是采用有焦点的窗口； 设置是否有窗口焦点但显示时不抢焦 点属性， 否则显示时激活窗口获取焦点； 在显示窗口前， 根据业务类型设 置窗口的 xAttr属性值； 对窗口进行隐藏和移动等其他业务相关操作。
创建窗口时： 根据窗口类型将窗口进行分类处理， 图形引擎提供带焦 点和不带焦点两种类型的窗口， 图形应用才艮据业务类型创建不同类型的窗 α。
窗口显示前： 图形应用根据业务类型设定表征窗口的显示相对层次的 窗口属性值， 例如 xAttr属性（实际应用可以采用业务 Z序等）值。
窗口显示时： 图形引擎 居窗口的窗口属性值（ xAttr属性值）在 Z轴 方向排列窗口并计算剪切区。
窗口切换时： 用户通过遥控器等输入设备， 例如双击某个按键， 触发 图形引擎弹出窗口列表， 用户通过方向键和确定键选择目标窗口， 图形引 擎内部预置一个禁止用户设置的、表示在屏幕顶层显示的 xAttr属性值 Zt。p, 用户选择并确定目标窗口后， 图形引擎关闭供用户选择的窗口列表， 图形 引擎把被切换出来的目标窗口的 xAttr属性值用 Zt。p临时值更新， 并且当所 述目标窗口是带焦点的窗口时， 激活所述目标窗口。
隐藏临时顶层窗口或者再次切换窗口时： 图形引擎恢复该目标窗口的 原来的真实 xAttr属性值， 并按照 xAttr属性值重排窗口显示次序。
焦点和按键事件派发： 焦点始终落到 xAttr属性表示在屏幕相对最顶层 显示的且带焦点的窗口上， 图形引擎把按键和焦点事件派发到对应的窗口 处理。
以下通过图 1至图 4, 对本发明进行详细说明。
图 1 显示了本发明实施例提供的多窗口显示和切换方法的流程图， 如 图 1所示， 所述方法主要包括：
步骤 101 : 图形引擎按照多个业务应用窗口的窗口属性值， 确定所述多 个业务应用窗口在屏幕上的叠加显示次序。
优选地， 所述窗口属性值是用于在屏幕 Z轴方向上对业务应用窗口进 行排序的类型元素值。
优选地， 图形引擎根据来自业务应用的应用程序请求， 将业务应用窗 口添加到窗口列表， 并将所述业务应用窗口与所述业务应用设置的窗口属 性值绑定， 以便确定多个窗口的叠加显示次序。
步骤 102: 当检测到终端用户需要将目标窗口切换到屏幕最顶层时， 图 形引擎使用预设的用于在屏幕最顶层显示窗口的窗口属性值替换所述目标 窗口的窗口属性值。
优选地， 图形引擎通过监控并拦截终端用户通过遥控器输入的窗口切 换请求， 向终端用户提供窗口列表， 以供终端用户选择待切换的目标窗口； 终端用户确定目标窗口后， 图形引擎使用图形系统预设的窗口属性值替换 其自身的窗口属性值， 使其具有临时的在屏幕 Z轴方向上最大的窗口属性 值。
步骤 103: 窗口属性值调整后， 重新进行窗口排序， 使目标窗口显示在 屏幕最顶层。
具体地，图形引擎提供某种名为 xAttr的窗口属性（其具体实现可以是： 例如， 业务应用 Z序， 即能表示各种不同的业务应用窗口在屏幕 Z轴方向 上的类型元素， 可以是数值或其它类型） 与窗口进行绑定， 决定多个窗口 在屏幕 Z轴方向的叠加显示顺序。 终端用户能够通过遥控器按键触发对话 框窗口， 选择切换到目标进程的窗口上。 为了不让窗口在切换过程中按照 其自身的窗口属性值显示， 层次属性 xAttr被改变， 图形系统内部预先设置 了一个禁止应用程序设置的用于在屏幕最顶层显示的窗口属性值， 用该窗 口属性值临时替换被切换出来的目标窗口自身的窗口属性 xAttr的值， 并在 该目标窗口被隐藏或者不考虑临时窗口属性 xAttr值的情况下， 恢复所述目 标窗口的 xAttr值为原来值， 然后图形引擎再根据这些窗口的 xAttr值决定 窗口的显示次序。
优选地， 当所述目标窗口是带焦点的窗口时， 图形引擎将按键焦点派 发至所述目标窗口进行处理， 否则， 将按键焦点派发至具有最大窗口属性 值的带焦点的窗口进行处理。 也就是说， 焦点按键事件始终发送至当前全 局窗口列表中 xAttr值表示在屏幕上显示在相对最顶层的、且带焦点的窗口 进行处理。
图 2是本发明实施例提供的窗口显示层次示例 （采用 Z序属性实现） 效果图， 如图 2所示， 本实施例采用窗口 Z序确定多个窗口 A、 B、 C的显 示层次。 用户依次向图形引擎发送用于窗口显示的应用程序请求， 请求显 示业务应用窗口八、 C、 B , 其中， 窗口 A、 C、 B的窗口属性值依次为 ZL、 ZH、 ZM, ZL ZM ZH。
图形窗口 居所述窗口属性值， 确定所述多个窗口在屏幕上的叠加显 示顺序为八、 C、 B , 如图 2所示为最终的显示效果。
本发明实施例还提供了一种多窗口显示和切换装置， 所述装置包括多 窗口显示模块和多窗口切换控制模块。 其中， 所述多窗口显示模块， 配置 为按照所述多个业务应用窗口的窗口属性值， 确定所述多个业务应用窗口 在屏幕上的叠加显示次序； 所述多窗口切换控制模块， 配置为当检测到终 端用户需要将目标窗口切换到屏幕最上层时， 使用预设的窗口属性值替换 所述目标窗口的窗口属性值， 并利用替换后的窗口属性值， 重新进行窗口 排序， 以便使目标窗口显示在屏幕最上层。
其中， 图 3是本发明实施例提供的多窗口切换控制模块的结构示意图 , 如图 3所示， 所述多窗口切换控制模块包括窗口列表管理子模块 31、 遥控 器按键拦截处理子模块 32、 窗口切换交互界面子模块 33、 焦点窗口仲裁处 理子模块 34、 临时窗口属性值更新处理子模块 35。
所述窗口列表管理子模块 31 , 配置为根据来自业务应用的应用程序请 求， 将业务应用窗口添加到窗口列表， 并将所述业务应用窗口与所述业务 应用设置的窗口属性值绑定。 具体地， 窗口列表管理子模块 31负责建立和 维护图形系统响应客户端请求而显示的窗口列表， 每个窗口有一个用于窗 口在屏幕上显示层次顺序的窗口属性。
所述遥控器按键拦截处理子模块 32 , 配置为监控并拦截终端用户通过 遥控器输入的窗口切换请求。 具体地， 遥控器按键拦截处理子模块 32 , 配 置为对终端用户遥控器输入进行拦截处理 , 根据键值的不同触发不同的业 务逻辑， 比如： 按下预先定义好的多窗口切换按键时， 触发对当前系统中 存活状态窗口的切换处理。
所述窗口切换交互界面子模块 33 , 配置为向终端用户提供窗口列表， 以供终端用户选择待切换的目标窗口。 具体地， 当终端用户通过遥控器按 键等触发窗口切换业务时， 弹出窗口切换交互界面， 并向终端用户提供用 于选择目标窗口的窗口列表， 在终端用户选中某个目标窗口时触发图形引 擎内部的多窗口间的切换处理逻辑。
所述焦点窗口仲裁处理子模块 34 , 配置为当所述目标窗口是带焦点的 窗口时， 图形引擎将按键焦点派发至所述目标窗口进行处理， 否则， 将按 键焦点派发至具有最大窗口属性值的带焦点的窗口进行处理。 具体地， 焦 点窗口仲裁处理子模块 34遍历当前的窗口列表， 并结合窗口属性值和状态 决定最新的焦点放到 Z序表征显示在最顶层且带有焦点的窗口上。 所述临时窗口属性值更新处理子模块 35 , 配置为在目标窗口隐藏或切 换时， 恢复所述目标窗口的窗口属性值。 当图形引擎内部处理窗口切换时， 采用临时的一个表示在最顶层显示窗口的窗口属性值更新窗口的实际窗口 属性值， 即使用预设 Z序临时替换窗口的实际 Z序， 并在窗口被隐藏或再 次切换到其它窗口时恢复其实际 Z序。
