Hi,

Here is my problem :
I want to add a background in a compartment. I found several subjects about it, but it doesn't work.

I used this code :

in a FreeFormLayerWithImageBGR class :

//********************************************************** *****************

public class FreeFormLayerWithImageBGR extends FreeformLayer {
Image image;
public FreeFormLayerWithImageBGR(String path) {
super();
try {
FileInputStream fis = new FileInputStream(path);
setImage(new Image(PlatformUI.getWorkbench().getDisplay(),fis));
System.out.println(fis.toString());

} catch (Exception e) {
System.out.println(e);
setImage(null);
}
}

public Image getImage() {
return image;
}

public void setImage(Image image) {
this.image = image;
}
@Override
protected void paintFigure(Graphics graphics) {
if (getImage() != null) {
Rectangle targetRect = getBounds().getCopy();
org.eclipse.swt.graphics.Rectangle imgBox = getImage().getBounds();
graphics.drawImage(getImage(), 0, 0, imgBox.width, imgBox.height,targetRect.x, targetRect.y, targetRect.width, targetRect.height);
//System.out.println("il est passé par ici");
}else {
System.out.println("error : no image");
}
super.paintFigure(graphics);
}
}

//********************************************************** *****************

and in the createFigure method of my ***compartmentEditPart :

//********************************************************** *****************

public IFigure createFigure() {
ResizableCompartmentFigure result = (ResizableCompartmentFigure) super.createFigure();
result.setTitleVisibility(false);
IFigure figure = new FreeFormLayerWithImageBGR("C:\\images\\background.jpeg");
result.repaint();

return result;
}

//********************************************************** *****************

but nothing happends ='(

(I tried to return figure but it returns an exception "FreeFormLayerWithImageBGR cannot be cast to ResizableCompartmentFigure")


Can you help me please?


Thanks,

Fenrir

hi fenrin..

try this... still having trouble but it works..

public IFigure createFigure() {
final ResizableCompartmentFigure result = (ResizableCompartmentFigure) super
.createFigure();
result.setTitleVisibility(false);

final Figure f = new FreeformLayer() {
@Override
protected void paintFigure(Graphics graphics) {
Image img = null;
try {
img = new org.eclipse.swt.graphics.Image(PlatformUI
.getWorkbench().getDisplay(), new FileInputStream(
new File("d:/images.jpg")));
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (img != null) {
Rectangle targetRect = result.getBounds();
org.eclipse.swt.graphics.Rectangle imgBox = img.getBounds();
graphics.drawImage(img, 0, 0, imgBox.width, imgBox.height,
targetRect.x, targetRect.y, targetRect.width,
targetRect.height);

} else {
System.out.println("error : no image");
}
super.paintFigure(graphics);

}
};

f.addFigureListener(new FigureListener() {

@Override
public void figureMoved(IFigure source) {

f.setBorder(new MarginBorder(source.getBounds().x));

}
});

f.setLayoutManager(new FreeformLayout());
result.repaint();
result.add(f, 0);

return result;
}
