Class METAVirtualKeyboard

java.lang.Object

org.lwjgl.openxr.METAVirtualKeyboard

public class METAVirtualKeyboard
extends Object

The XR_META_virtual_keyboard extension.

The virtual keyboard extension provides a system-driven localized keyboard that the application has full control over in terms of positioning and rendering.

This is achieved by giving the application the data required to drive rendering and animation of the keyboard in response to interaction data passed from the application to the runtime.

This approach is an alternative to a potential system keyboard overlay solution and provides a keyboard that can seamlessly blend into the application environment, since it is rendered by the same system, and avoids input focus issues that might come with a system overlay.

The API is also designed to work with custom hand and/or controller models in various games and applications.

Create a virtual keyboard.

C Specification

The CreateVirtualKeyboardMETA function is defined as:

 XrResult xrCreateVirtualKeyboardMETA(
     XrSession                                   session,
     const XrVirtualKeyboardCreateInfoMETA*      createInfo,

On failure, this command returns

• ERROR_FUNCTION_UNSUPPORTED
• ERROR_VALIDATION_FAILURE
• ERROR_RUNTIME_FAILURE
• ERROR_HANDLE_INVALID
• ERROR_INSTANCE_LOST
• ERROR_SESSION_LOST
• ERROR_OUT_OF_MEMORY
• ERROR_LIMIT_REACHED

xrCreateVirtualKeyboardSpaceMETA

public static int xrCreateVirtualKeyboardSpaceMETA(XrSession session,
 XrVirtualKeyboardMETA keyboard,
 XrVirtualKeyboardSpaceCreateInfoMETA createInfo,
 org.lwjgl.PointerBuffer keyboardSpace)

Create a virtual keyboard space.

C Specification

The CreateVirtualKeyboardSpaceMETA function is defined as:

 XrResult xrCreateVirtualKeyboardSpaceMETA(
     XrSession                                   session,
     XrVirtualKeyboardMETA                       keyboard,

Unsafe version of: SetVirtualKeyboardModelVisibilityMETA

xrSetVirtualKeyboardModelVisibilityMETA

public static int xrSetVirtualKeyboardModelVisibilityMETA(XrVirtualKeyboardMETA keyboard,
 XrVirtualKeyboardModelVisibilitySetInfoMETA modelVisibility)

Set virtual keyboard model visibility.

C Specification

The SetVirtualKeyboardModelVisibilityMETA function is defined as:

To get the actual visibility state of the render model, the application should wait for the XrEventDataVirtualKeyboardShownMETA and XrEventDataVirtualKeyboardHiddenMETA events.

Valid Usage (Implicit)

• The XR_META_virtual_keyboard extension must be enabled prior to calling SetVirtualKeyboardModelVisibilityMETA
• keyboard must be a valid XrVirtualKeyboardMETA handle
• modelVisibility must be a pointer to a valid XrVirtualKeyboardModelVisibilitySetInfoMETA structure

Return Codes

On success, this command returns

• SUCCESS
• SESSION_LOSS_PENDING

On failure, this command returns

The GetVirtualKeyboardModelAnimationStatesMETA function is defined as:

 XrResult xrGetVirtualKeyboardModelAnimationStatesMETA(
     XrVirtualKeyboardMETA                       keyboard,
     XrVirtualKeyboardModelAnimationStatesMETA*  animationStates);

Description

This function follows the two-call idiom for filling the animationStates array in the XrVirtualKeyboardModelAnimationStatesMETA structure. Note that new animations may be added after the runtime processes inputs from SendVirtualKeyboardInputMETA. Therefore, after sending new keyboard inputs the application should query the buffer size again before getting any animation data.

Valid Usage (Implicit)
