示例1: replaceSurfaceData
import sun.java2d.NullSurfaceData; //导入依赖的package包/类
public SurfaceData replaceSurfaceData() {
if (getBounds().isEmpty()) {
surfaceData = NullSurfaceData.theInstance;
return surfaceData;
}
// the layer redirects all painting to the buffer's graphics
// and blits the buffer to the layer surface (in drawInCGLContext callback)
CGraphicsConfig gc = (CGraphicsConfig)getGraphicsConfiguration();
surfaceData = gc.createSurfaceData(this);
setScale(gc.getDevice().getScaleFactor());
// the layer holds a reference to the buffer, which in
// turn has a reference back to this layer
if (surfaceData instanceof CGLSurfaceData) {
validate((CGLSurfaceData)surfaceData);
}
return surfaceData;
