Method Detail

createContext

public GLContext createContext(GLContext shareWith)

Description copied from interface: GLDrawable

Creates a new context for drawing to this drawable that will optionally share display lists and other server-side OpenGL objects with the specified GLContext.

The GLContext share need not be associated with this GLDrawable and may be null if sharing of display lists and other objects is not desired. See the note in the overview documentation on context sharing.

setRealized

public void setRealized(boolean realized)

Description copied from interface: GLDrawable

Indicates to on-screen GLDrawable implementations whether the underlying window has been created and can be drawn into. This method must be called from GLDrawables obtained from the GLDrawableFactory via the GLDrawableFactory.getGLDrawable() method. It must typically be called with an argument of true in the addNotify method of components performing OpenGL rendering and with an argument of false in the removeNotify method. Calling this method has no other effects. For example, if removeNotify is called on a Canvas implementation for which a GLDrawable has been created, it is also necessary to destroy all OpenGL contexts associated with that GLDrawable. This is not done automatically by the implementation. It is not necessary to call setRealized on a GLCanvas, a GLJPanel, or a GLPbuffer, as these perform the appropriate calls on their underlying GLDrawables internally..

Specified by:

setRealized in interface GLDrawable

Overrides:

setRealized in class X11GLDrawable

setSize

public void setSize(int width,
           int height)

Description copied from interface: GLDrawable

Requests a new width and height for this GLDrawable. Not all drawables are able to respond to this request and may silently ignore it.

getWidth

public int getWidth()

Description copied from interface: GLDrawable

Returns the current width of this GLDrawable.

getHeight

public int getHeight()

Description copied from interface: GLDrawable

Returns the current height of this GLDrawable.

swapBuffers

public void swapBuffers()
                 throws GLException

Description copied from interface: GLDrawable

Swaps the front and back buffers of this drawable. For GLAutoDrawable implementations, when automatic buffer swapping is enabled (as is the default), this method is called automatically and should not be called by the end user.

Specified by:

swapBuffers in interface GLDrawable

Overrides:

swapBuffers in class X11GLDrawable

Throws:

GLException

lockSurface

public int lockSurface()
                throws GLException

Throws:

GLException

unlockSurface

public void unlockSurface()
