Method Detail

createBuffer

public java.awt.image.BufferedImage createBuffer(int w,
                                                 int h)

Specified by:

createBuffer in class J2DPresentable

lockResources

public boolean lockResources(PresentableState pState)

Description copied from interface: Presentable

Locks any underlying resources needed for a createGraphics/prepare/present sequence and returns a boolean indicating if the presentable needs to be recreated. If the method returns true and the Presentable implements GraphicsResource then its dispose() method will be called prior to recreating a new Presentable object and so no resource should need to be locked in that case. The resources will be unlocked in either #prepare() or Presentable.present().

Parameters:

pState - The presentation state for the upcoming pulse

Returns:

true if the caller should recreate the Presentable

prepare

public boolean prepare(Rectangle dirty)

Description copied from interface: Presentable

display the indicated region to the user.

Parameters:

dirty - display region or null for full area

Returns:

true if the provided region was successfully displayed, false otherwise

present

public boolean present()

Description copied from interface: Presentable

present the prepared region to the user.

getContentWidth

public int getContentWidth()

getContentHeight

public int getContentHeight()

setOpaque

public void setOpaque(boolean opaque)

isOpaque

public boolean isOpaque()
