OpenGLContext

open class OpenGLContext(var context: Context? = null) : IOpenGLContext

OpenGLContext open object.

Constructors

constructor(context: Context? = null)

Properties

val address: Long

Address of native referenced object. nullptr if not referencing any native allocated object. Note native allocation will happen only once.

var context: Context?

val displayType: EDisplayType

Context attached display type

val dpi: Int

Context attached display DPI in physicals pixels / inch

val encoding: EImagePixelFormat

Encoding.

val fontModifiers: Pair<Float, Boolean>

Fonts modifiers

outputBufferType

val outputBufferType: IOpenGLContext.EOutputBufferType

Render buffer output type

val pixelRatio: Float

Context attached physical / logical pixel ratio

val safeArea: Rect?

Safe area rectangle specific for new iPhones

val systemContext: Long

System rendering context address (platform-dependent)

textureScaleFactor

val textureScaleFactor: Float

Textures scale factor.

val viewport: Rect?

Viewport rectangle associated with this rendering context

Functions

open override fun doAction(act: IOpenGLContext.EAction): Boolean

The function is called when the SDK request an operation on the context.

open override fun doneCurrent(): Boolean

Make no GL context the current context. After this method no GL functions will be called by the engine.

Overrides finalize that garbage collector will call when needed.

open override fun getCapability(qCap: IOpenGLContext.ECapability): Boolean

open override fun initialize(): Boolean

Create a new GL context.

isDelayedInitializationRequired

open override fun isDelayedInitializationRequired(): Boolean

Check if delayed initialization is required By returning true, all OpenGL context dependent objects ( screens, canvases, views ) will be initialized on the first Screen.render call The delay initialization can be used when OpenGL context dependent objects are created before the context is ready to use

open override fun isInitialized(): Boolean

Get initialized status.

fun isReference(): Boolean

True if keeps a reference to a C++ SDK object False if keeps a C++ SDK object

open override fun makeCurrent(): Boolean

Make this context the current OpenGL rendering context. All GL functions you call operate on this context until another context is made current.

open override fun needsRender()

GL context owner render request This notification is sent only when a screen render rule is set to ERR_Automatic

operator fun not(): Boolean

Checks if this object is valid.

Releases the native referenced value of this object if:
