Method Details

getSystemListener

public SystemListener getSystemListener()

Accesses the listener that receives events related to this context.

Specified by:

getSystemListener in interface JmeContext

Returns:

the pre-existing instance

setSystemListener

public void setSystemListener(SystemListener listener)

Description copied from interface: JmeContext

Sets the listener that will receive events relating to context creation, update, and destroy.

Specified by:

setSystemListener in interface JmeContext

Parameters:

listener - the desired listener

printContextInitInfo

protected void printContextInitInfo()

getGLVersion

protected int[] getGLVersion(String renderer)

createContextAttribs

protected org.lwjgl.opengl.ContextAttribs createContextAttribs()

determineMaxSamples

protected int determineMaxSamples(int requestedSamples)

loadNatives

protected void loadNatives()

getNumSamplesToUse

protected int getNumSamplesToUse()

reinitContext

protected void reinitContext()

Reinitializes the relevant details of the context. For internal use only.

initContextFirstTime

protected void initContextFirstTime()

Initializes the LWJGL renderer and input for the first time. For internal use only.

initOpenCL

protected void initOpenCL()

internalDestroy

public void internalDestroy()

internalCreate

public void internalCreate()

create

public void create()

destroy

public void destroy()

waitFor

protected void waitFor(boolean createdVal)

isCreated

public boolean isCreated()

Specified by:

isCreated in interface JmeContext

Returns:

True if the context has been created but not yet destroyed.

isRenderable

public boolean isRenderable()

Specified by:

isRenderable in interface JmeContext

Returns:

True if the context contains a valid render surface, if any of the rendering methods in Renderer are called while this is false, then the result is undefined.

setSettings

public void setSettings(AppSettings settings)

Specified by:

setSettings in interface JmeContext

Parameters:

settings - the display settings to use for the created context. If the context has already been created, then restart() must be called for the changes to be applied.

getSettings

public AppSettings getSettings()

Specified by:

getSettings in interface JmeContext

Returns:

The current display settings. Note that they might be different from the ones set with setDisplaySettings() if the context was restarted or the settings changed internally.

getRenderer

public Renderer getRenderer()

Specified by:

getRenderer in interface JmeContext

Returns:

The renderer for this context, or null if not created yet.

getTimer

public Timer getTimer()

Specified by:

getTimer in interface JmeContext

Returns:

The timer for this context, or null if not created yet.

getOpenCLContext

public Context getOpenCLContext()

Specified by:

getOpenCLContext in interface JmeContext

Returns:

The OpenCL context if available.

getFramebufferHeight

public int getFramebufferHeight()

Returns the height of the framebuffer.

Specified by:

getFramebufferHeight in interface JmeContext

Returns:

the height (in pixels)

getFramebufferWidth

public int getFramebufferWidth()

Returns the width of the framebuffer.

Specified by:

getFramebufferWidth in interface JmeContext

Returns:

the width (in pixels)

getWindowXPosition

public int getWindowXPosition()

Returns the screen X coordinate of the left edge of the content area.

Specified by:

getWindowXPosition in interface JmeContext

Returns:

the screen X coordinate

getWindowYPosition

public int getWindowYPosition()

Returns the screen Y coordinate of the top edge of the content area.

Specified by:

getWindowYPosition in interface JmeContext

Returns:

the screen Y coordinate
