Function Description

OH_InputMethodController_Attach()

InputMethod_ErrorCode OH_InputMethodController_Attach(InputMethod_TextEditorProxy *textEditorProxy,InputMethod_AttachOptions *options, InputMethod_InputMethodProxy **inputMethodProxy)

Description

Binds an application to the input method service.

Since: 12

Parameters

Name	Description
InputMethod_TextEditorProxy *textEditorProxy	Pointer to the InputMethod_TextEditorProxy instance. The caller needs to manage the textEditorProxy lifecycle. If the calling is successful, the caller cannot release textEditorProxy before the next binding or unbinding call.
InputMethod_AttachOptions *options	Pointer to the InputMethod_AttachOptions instance. This parameter is used to specify the options of attaching an input method.
InputMethod_InputMethodProxy **inputMethodProxy	Double pointer to the InputMethod_InputMethodProxy instance. The lifecycle lasts until the next binding or unbinding call.

Returns

Type	Description
InputMethod_ErrorCode	An error code. IME_ERR_OK - Success. IME_ERR_PARAMCHECK - Parameter error. IME_ERR_IMCLIENT - Client error in input method. IME_ERR_IMMS - Input method service error. IME_ERR_NULL_POINTER - An unexpected null pointer. For details about the error codes, see InputMethod_ErrorCode.

OH_InputMethodController_AttachWithUIContext()

InputMethod_ErrorCode OH_InputMethodController_AttachWithUIContext(ArkUI_ContextHandle context, InputMethod_TextEditorProxy *textEditorProxy, InputMethod_AttachOptions *options, InputMethod_InputMethodProxy **inputMethodProxy)

Description

Binds an application to the input method service.

Since: 23

Parameters

Name	Description
ArkUI_ContextHandle context	Pointer to the ArkUI_Context instance.
InputMethod_TextEditorProxy *textEditorProxy	Pointer to the InputMethod_TextEditorProxy instance. The caller needs to manage the textEditorProxy lifecycle. If the calling is successful, the caller cannot release textEditorProxy before the next binding or unbinding call.
InputMethod_AttachOptions *options	Pointer to the InputMethod_AttachOptions instance. This parameter is used to specify the options of attaching an input method.
InputMethod_InputMethodProxy **inputMethodProxy	Double pointer to the InputMethod_InputMethodProxy instance. The lifecycle lasts until the next binding or unbinding call.

Returns

Type	Description
InputMethod_ErrorCode	An error code. IME_ERR_OK - Success. IME_ERR_PARAMCHECK - Parameter error. IME_ERR_IMCLIENT - Client error in input method. IME_ERR_IMMS - Input method service error. IME_ERR_NULL_POINTER - An unexpected null pointer. For details about the error codes, see InputMethod_ErrorCode.
