1# 窗口子系统变更说明 2 3## cl.window.1 OH_NativeWindowManager_RegisterKeyEventFilter接口注册的回调事件中，回调函数参数Input_KeyEvent注入变更 4 5**访问级别** 6 7公开接口 8 9**变更原因** 10 11修复回调函数注入[Input_KeyEvent](../../../application-dev/reference/apis-input-kit/input.md)结构体的[Input_KeyEventAction](../../../application-dev/reference/apis-input-kit/input.md#input_keyeventaction)字段时，注入值无法匹配枚举的bug。变更前注入Input_KeyEventAction的值为1、2、3分别对应取消（KEY_ACTION_CANCEL）、按下（KEY_ACTION_DOWN）和抬起（KEY_ACTION_UP）三种行为，与枚举中定义的0（KEY_ACTION_CANCEL）、1（KEY_ACTION_DOWN）、2（KEY_ACTION_UP）不匹配。 12 13**变更影响** 14 15该变更为不兼容变更。<br/> 16变更前，注入Input_KeyEvent中的Input_KeyEventAction为1、2、3，无法匹配枚举。<br/> 17变更后，注入Input_KeyEvent中的Input_KeyEventAction为0、1、2，匹配枚举。<br/> 18 19**起始API Level** 20 21API 12 22 23**变更发生版本** 24 25从OpenHarmony 5.0.0.38 版本开始。 26 27**变更的接口/组件** 28 29OH_NativeWindowManager_RegisterKeyEventFilter接口中，回调函数OH_NativeWindowManager_KeyEventFilter的注入实现。 30 31**适配指导** 32 33注入行为bug修复，开发者之前用code作硬编码需要改为对应的Input_KeyEventAction枚举。 34 35## cl.window.2 startAbility/openLink锁屏时限制拉起行为 36 37**访问级别** 38 39公开接口 40 41**变更原因** 42 43锁屏时对任意拉起应用的行为增加限制。 44 45**变更影响** 46 47该变更为不兼容变更。 48变更前：锁屏时可调用startAbility/openLink接口正常拉起应用并正常保持应用窗口为前台状态。 49变更后：锁屏时调用startAbility/openLink接口拉起应用时，当应用窗口到前台状态时会被窗口管理阻止进而关闭窗口和应用。 50 51**起始API Level** 52 536 54 55**变更发生版本** 56 57从OpenHarmony SDK
