Hi all,
I'm experimenting with GMF trying to figure out how things work and ran
into a bit of a problem.
From various other posts I found a way of having an image background in
my diagram, but after adding the code below I cant create new
elements/nodes to it?
I created a FreeFormImageLayer class like this:
public class FreeFormImageLayer extends FreeformLayer {
Image image;
DiagramEditPart ownerEditPart;
public FreeFormImageLayer(final Image image, final DiagramEditPart
ownerEditPart){
this.image = image;
this.ownerEditPart = ownerEditPart;
}
public Image getImage() {
return image;
}
public void setImage(Image image) {
this.image = image;
}
protected void paintFigure(Graphics graphics) {
if (getImage() != null) {
Rectangle targetRect = getBounds().getCopy();
Rectangle r = getBounds().getCopy();
ownerEditPart.getFigure().translateToParent(r);
r.intersect(ownerEditPart.getFigure().getClientArea());
org.eclipse.swt.graphics.Rectangle imgBox = getImage().getBounds();
System.out.printf("r=(%d,%d,%d,%d)\n",
r.x, r.y, r.width, r.height);
System.out.printf("(%d,%d,%d,%d) -> (%d,%d,%d,%d)\n",
imgBox.x, imgBox.y, imgBox.width, imgBox.height,
targetRect.x, targetRect.y, targetRect.width, targetRect.height);
long t1 = System.currentTimeMillis();
System.out.println("Start draw image");
/*
graphics.drawImage(getImage(), 0, 0, imgBox.width, imgBox.height,
targetRect.x, targetRect.y, targetRect.width,
targetRect.height);
*/
System.out.println("Graphics absolute scale: "
+graphics.getAbsoluteScale());
graphics.drawImage(getImage(), 0, 0);
System.out.println("End draw image, took
"+(System.currentTimeMillis()-t1) +" ms");
}
super.paintFigure(graphics);
}
@Override
public Rectangle getFreeformExtent() {
// TODO Auto-generated method stub
//return super.getFreeformExtent();
return new Rectangle(0,0, image.getBounds().width/10,
image.getBounds().height/10);
}
}
Which I then add to my diagram edit part in its createFigure like this:
protected IFigure createFigure() {
System.out.println(getClass().getName() + " : In createFigure()");
image = null;
EObject eObj = ((Diagram)getModel()).getElement();
String fileStr =((Project)eObj).getMapFile();
fileStr = "/home/mikael/Desktop/mapClean.jpg";
createImages( fileStr );
ScalableLayeredPane pane = new ScalableLayeredPane();
pane.setBounds(new Rectangle(image.getBounds()));
imageLayer = new FreeFormImageLayer(image,this);
pane.add(imageLayer);
pane.add(contentPane = super.createFigure());
System.out.println(getClass().getName() +"End createFigure");
return pane;
}
void createImages(final String fileStr){
InputStream is;
try {
is = new FileInputStream(fileStr);
image = new Image(PlatformUI.getWorkbench().getDisplay(), is);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}//Thread.currentThread().getContextClassLoader().getResourc eAsStream(
fileStr );
if(image == null){
image = new Image(PlatformUI.getWorkbench().getDisplay(),300,300);
image.setBackground(ColorConstants.blue);
}
}
Please ignore all the print statements, I'm having another issue with
extremely slow (2.5 second) render times when zooming the slightest.
Any help really appreciated.
Cheers,
Micke

Anyone out there who has successfully managed to add a diagram
background which covers the entire diagram (not like the taipan example
which only covers the bottom right)?
If so I'd be gratefull if you could post your solution.
Cheers

Hi Mikael,
I am not sure this has anything to do with your situation, but I
remember having problems with creating elements inside nodes when using
layers and layered panes. I overrode method isOpaque() to always return
false and that helped.
Best regards,
Boris

Thanks for the suggestion Boris, unfortunately it didn't help. Overrode
the isOpaque method on my FreeFormImageLayer class.
Another thing I've noticed is that changing propeties for the Diagram
object in the properties view doesn't work properly.
After entering a String and pressing enter it goes blank, but when
clicking on the field, selecting it, the value entered is displayed.
Cheers

Due to the lack of replies I suspect that; the question wasn't very
clear , this is not a gmf problem or a RTFM issue.
Would be nice top pinpoint which of the three it is, would be very
grateful if someone with a bit of experience could reply. Because I'm at
the point of giving up on this.
Cheers,
Micke

Micke,
I can still add ship shapes on a Taipan diagram even right on top of the
background image. I would suggest debugging your code and comparing
with what happens in the Taipan diagram. Without knowing anything about
what is going wrong, I would say a good starting point would be to put a
breakpoint in the CreationEditPolicy.getCommand() method and try
creating a shape.
Regards,
Cherie
