Hi Tomas,
did you find a solution? I added the following code to the
<whatever>EditPart.java for the <whatever> class inside:
public void paintFigure(Graphics g) {
Rectangle bounds = getPrimaryFigureBounds();
Point topLeft = bounds.getTopLeft();
Point bottomRight = bounds.getBottomRight();
Pattern pattern = new Pattern(Display.getCurrent(), topLeft.x,
topLeft.y, bottomRight.x, bottomRight.y,
ColorConstants.white, ColorConstants.darkBlue);
g.setBackgroundPattern(pattern);
g.fillRectangle(bounds);
}
well, but what should I say ... It didn't work. I am a little bit
surpriced since the following code generates a box (whithout gradient)
as expected:
public void paintFigure(Graphics g) {
// Rectangle bounds = getPrimaryFigureBounds();
//
// Point topLeft = bounds.getTopLeft();
// Point bottomRight = bounds.getBottomRight();
// Pattern pattern = new Pattern(Display.getCurrent(), topLeft.x,
// topLeft.y, bottomRight.x, bottomRight.y,
// ColorConstants.white, ColorConstants.darkBlue);
//
// g.setBackgroundPattern(pattern);
g.fillRectangle(bounds);
}
Maybe someone could shade some light on this, why the pattern does not work.

Martin

To filling scalable polygons and ellipses with gradient? No.

I am confused, are you trying to fill a rectangle? To do this I do:
public xyzFigure() {
....
this.setBackgroundColor(ColorConstants.orange);
this.setForegroundColor(ColorConstants.white);
this.setBorder(new LineBorder(ColorConstants.black, 1));
createContents();
}
/**
* @generated NOT
*/
@Override
protected void fillShape(Graphics graphics) {
graphics.fillGradient(getBounds(), true);
}
I am a little bit

You won't get a gradient without setting foreground and background color.
As I mentioned, I am not quite sure I understood what you meant, but I
hope this helps!

Hi Tomas,

I think we are not talking about exactly the same thing. My Figures in
GMF are children org.eclipse.gmf.runtime.gef.ui.figures.NodeFigure,
which does not have a method called fillShape. fillShape is a method of
Shape as far as I understand. So the method that I am using is paintFigure.
paintFigure now take org.eclipse.draw2d.Graphics as a parameter which is
the parent of ScaledGraphics. So I am confused why you are saying you
didn't manage to get a solution for scalable polygons and ellipses.
(2)
As I understood the Pattern class it takes two colors to create the
gradient. So why sould I then set the foreground and background class.

Hi Tomas,
Hm, I'm actually traing to learn as much as possible from GMF, thats why
I am following the newsgroup intensivly. So I thought that shapes with
gradient would be a cute idea for my project ;-) Well but the bad news
is, that I havn't done it yet ....
About out discussion on org.eclipse.draw2d.Shape and
org.eclipse.gmf.runtime.gef.ui.figures.NodeFigure both implement the
IFigure interface and I think this is key. I guess you are not using
customizable figures so maybe hen the code generater just generates a
Shape object. Nevertheless NodeFigure doesn't have the fillShape method ...

Ok. One of us is bound to figure it out sooner or later!

I use Scalable Polygons with template points. This generates figures
which extends draw2d.Shape, this class has both methods (paint and
fill). I guess they do the same?
Reading on the GEF newsgroup, background patterns seems like the only
solution available (but even they seem have much trouble with that).
