org.eclipse.swt.widgets.Composite
org.jzy3d.plot3d.rendering.canvas.PanamaGLSWTCanvas
All Implemented Interfaces:
org.eclipse.swt.graphics.Drawable, ICanvas, IPanamaGLCanvas, IScreenCanvas
public class PanamaGLSWTCanvas extends org.eclipse.swt.widgets.Composite implements IPanamaGLCanvas
An SWT Composite hosting a PanamaGL-backed GLCanvasSWT. Ships the very same PanamaGLCanvasSupport plumbing as the Swing and JavaFX panels, while exposing itself as a regular SWT Composite so it can be dropped into any SWT widget hierarchy.

      Advanced / test-friendly constructor: inject a pre-built GLCanvasSWT. The supplied canvas is re-parented to this composite so that the FillLayout can drive its size. Use the main constructor in application code.

    • firePixelScaleChanged

      protected void firePixelScaleChanged(double pixelScaleX, double pixelScaleY)

    • getGLCanvas

      public panamagl.canvas.GLCanvas getGLCanvas()
      Methods that simply forward to glCanvas go through the field directly rather than through support.

      SWT's ThreadRedirect_SWT runs the GL init synchronously when already on the display thread, which is exactly the case while PanamaGLCanvasSupport's constructor wires glCanvas.setGLEventListener(renderer). The init walks back through Renderer3D.init -> View.init into the canvas — first PanamaGLPainter.configureGL(Quality) calls getGLCanvas(), then View.initResources -> updateBounds -> shoot calls forceRepaint() — all before support has been assigned. Calling glCanvas keeps these paths NPE-free; the field and support.getGLCanvas() reference the same object.

    • getRendererWidth

      public int getRendererWidth()
      Renderer dimensions are reported in physical pixels, matching the FBO size that the underlying GLCanvasSWT allocates. View uses these values to build the ViewportConfiguration that drives glViewport; on a Retina display the FBO is 2W x 2H so we must return 2W and 2H here, otherwise glViewport(0, 0, W, H) only fills the bottom-left quadrant of the FBO.

      When HiDPI is disabled (Jzy3D's Quality.preserveViewportSize=true), the FBO is already in logical pixels and getPhysicalWidth() returns the logical width.

    • addMouseController

      public void addMouseController(Object o)
      Register an SWT controller on the underlying GLCanvasSWT.

      The controller is expected to implement one or more of SWT's mouse listener interfaces (MouseListener, MouseMoveListener, MouseWheelListener, MouseTrackListener). Each implemented interface is wired up to the canvas; missing ones are silently ignored — same lenient behavior as the AWT canvas's addMouseController(Object).
