Method Detail

setG2D

public void setG2D(GLGraphics2D g2d)

Description copied from interface: G2DDrawingHelper

Sets the current GLGraphics2D parent. The current GL and GLContext objects can be accessed from this. This should clear all internal stacks in the helper object because previous painting iterations may not have called dispose() for each time they called create().

Specified by:

setG2D in interface G2DDrawingHelper

Parameters:

g2d - The parent context for subsequent drawing operations.

push

public void push(GLGraphics2D newG2d)

Description copied from interface: G2DDrawingHelper

Sets the new GLGraphics2D context in a stack. This is called when Graphics2D.create() is called and each helper is given notice to push any necessary information onto the stack. This is used in conjunction with G2DDrawingHelper.pop(GLGraphics2D).

Specified by:

push in interface G2DDrawingHelper

Parameters:

newG2d - The new context, top of the stack.

pop

public void pop(GLGraphics2D parentG2d)

Description copied from interface: G2DDrawingHelper

Sets the new GLGraphics2D context in a stack after a pop. This is called when Graphics2D.dispose() is called and each helper is given notice to pop any necessary information off the stack. This is used in conjunction with G2DDrawingHelper.push(GLGraphics2D).

Specified by:

pop in interface G2DDrawingHelper

Parameters:

parentG2d - The new context, top of the stack - which is actually the parent of what was popped.

setHint

public void setHint(RenderingHints.Key key,
           Object value)

Description copied from interface: G2DDrawingHelper

Sets a new rendering hint. The state of all rendering hints is kept by the GLGraphics2D object, but all new state changes are propagated to all listeners.

Specified by:

setHint in interface G2DDrawingHelper

Parameters:

key - The rendering hint key.

value - The new hint value.

resetHints

public void resetHints()

Description copied from interface: G2DDrawingHelper

Clears all hints back to their default states.

Specified by:

resetHints in interface G2DDrawingHelper

dispose

public void dispose()

Description copied from interface: G2DDrawingHelper

Disposes the helper object. This is not called during the dispose operation of the Graphics2D object. This should dispose all GL resources when all drawing is finished and no more calls will be executing on this OpenGL context and these resources.

Specified by:

dispose in interface G2DDrawingHelper

drawImage

                int x,
