public abstract class AbstractVisionBufferedComponent extends AbstractVisionComponent
This class is a subclass of AbstractFPMIComponent that provides the basic bookeeping required for creating a cached, buffered component. That is, a component that draws itself to a BufferedImage when something has changed, and then uses that buffered image in paintComponent(). Make sure that your component properly uses isOpaque() so that you get the correct type of buffered image used.- See Also:

paintComponent
protected void paintComponent(java.awt.Graphics g)
- Overrides:
paintComponent
in classAbstractVisionComponent
-
drawBuffer
protected abstract void drawBuffer(java.awt.Graphics2D g, int width, int height)
Subclasses only need to implement this function to have buffered functionality. If anything changes about the component (besides component size), such as colors or line thicknesses, call invalidateBuffer() to ensure this is called again on the next repaint- Parameters:
g
- A graphics object that will paint onto the off-screen buffer
-
invalidateBuffer
protected void invalidateBuffer()
-
repaintAndInvalidateBuffer
protected void repaintAndInvalidateBuffer()
