Class CanvasNewtSWT

java.lang.Object
org.eclipse.swt.widgets.Widget
org.eclipse.swt.widgets.Control
org.eclipse.swt.widgets.Scrollable

org.jzy3d.chart.factories.CanvasNewtSWT
All Implemented Interfaces:
org.eclipse.swt.graphics.Drawable, ICanvas, INativeCanvas, IScreenCanvas
public class CanvasNewtSWT extends org.eclipse.swt.widgets.Composite implements IScreenCanvas, INativeCanvas
A Newt canvas wrapped in an AWT Newt is supposed to be faster than any other canvas, either for AWT or Swing. If a non AWT panel where required, follow the guidelines given in IScreenCanvas documentation.

    • setPixelScale

      public void setPixelScale(float[] scale)
      Description copied from interface: ICanvas
      Defines pixel scale. On MacOS Retina displays, a X*Y chart uses a (X*2)*(Y*2) viewport. This makes some calculation based on viewport (such as Camera.screenToModel(IPainter, org.jzy3d.maths.Coord3d) output wrong result. When running on Retina display, those two options fixed buggy mouse selections on Retina:
      • setPixelScale(new float[]{0.5f,0.5f})
