Constructor Details

LwjglCanvas

public LwjglCanvas()

Method Details

getType

public JmeContext.Type getType()

Specified by:

getType in interface JmeContext

Specified by:

getType in class LwjglAbstractDisplay

Returns:

Type.Display or Type.Canvas

create

public void create(boolean waitFor)

Description copied from interface: JmeContext

Creates the context and makes it active.

Specified by:

create in interface JmeContext

Parameters:

waitFor - If true, will wait until context has initialized.

setTitle

public void setTitle(String title)

Description copied from class: LwjglAbstractDisplay

Set the title if it's a windowed display

Specified by:

setTitle in interface JmeContext

Specified by:

setTitle in class LwjglAbstractDisplay

Parameters:

title - the desired title

restart

public void restart()

Description copied from class: LwjglAbstractDisplay

Restart if it's a windowed or full-screen display.

Specified by:

restart in interface JmeContext

Specified by:

restart in class LwjglAbstractDisplay

getCanvas

public Canvas getCanvas()

Specified by:

getCanvas in interface JmeCanvasContext

runLoop

protected void runLoop()

Description copied from class: LwjglAbstractDisplay

execute one iteration of the render loop in the OpenGL thread

Overrides:

runLoop in class LwjglAbstractDisplay

acquirePixelFormat

protected org.lwjgl.opengl.PixelFormat acquirePixelFormat(boolean forPbuffer)

It seems it is best to use one pixel format for all shared contexts.

Parameters:

forPbuffer - true→zero samples, false→correct number of samples

Returns:

a new instance

makePbufferAvailable

protected void makePbufferAvailable()
                             throws org.lwjgl.LWJGLException

Makes sure the pbuffer is available and ready for use

Throws:

org.lwjgl.LWJGLException - if the buffer can't be made current

destroyPbuffer

protected void destroyPbuffer()

destroyContext

protected void destroyContext()

This is called: 1) When the context thread ends 2) Any time the canvas becomes non-displayable

Specified by:

destroyContext in class LwjglAbstractDisplay

createContext

protected void createContext(AppSettings settings)

This is called: 1) When the context thread starts 2) Any time the canvas becomes displayable again. In the first call of this method, OpenGL context is not ready yet. Therefore, OpenCL context cannot be created. The second call of this method is done after "simpleInitApp" is called. Therefore, OpenCL won't be available in "simpleInitApp" if Canvas/Swing is used. To use OpenCL with Canvas/Swing, you need to use OpenCL in the rendering loop "simpleUpdate" and check for "context.getOpenCLContext()!=null".

Specified by:

createContext in class LwjglAbstractDisplay

Parameters:

settings - the AppSettings to apply
