Re: [udig-devel] Developing Plugin

[Cole Markham <markhamc@xxxxxxxxx>]

You need to add an SWT Composite to the Shell. A good one would
probably be a Canvas:
http://help.eclipse.org/help31/topic/org.eclipse.platform.doc.isv/reference/api/org/eclipse/swt/widgets/Canvas.html

Canvas canvas = new Canvas(shell, SWT.DOUBLE_BUFFERED);

Then you would need to create a GC (graphics context,
org.eclipse.swt.graphics.GC) object from the Canvas (it implements
Drawable). You can use that instead of the image to create the
SWTGraphics object and it should work.

I want to draw in a other window (a SWT shell) the image obtained with RenderedImage from the uDIg's map . To achieve this I have written this code:

  Display display = new Display();
  Shell shell = new Shell(display);
  shell.setText("Demo"); 
  shell.setLayout(new FillLayout());
   
  RenderManager manager =(RenderManager)getContext().getMap().getRenderManager();
  RenderedImage renderedImage = manager.getRenderExecutor().getContext().getImage(); 
  
  Image image = new Image(display, renderedImage.getWidth(),renderedImage.getHeight());
  SWTGraphics graphicSWT = new SWTGraphics(image, display);
  graphicSWT.drawImage(renderedImage,0,0);

In the last step the program stops. This code doesn't work and surely it's wrong. Somebody knows how I can obtain to draw a renderedImage in a shell?
