I'd like to draw a gradient background for a FigureCanvas. Unfortunately the code which works for Composites or similars does not work for my FigureCanvas. Where it makes a perfect gradient background on my Composite it simply puts one color as background of my FigureCanvas.

Here is a snippetof how it works with all my other Controls.

Rectangle rect = parent.getClientArea();
Image newImage = new Image(parent.getDisplay(), 1, Math.max(1,
rect.height));
GC gc = new GC(newImage);
gc.setForeground(composite.getDisplay().getSystemColor(SWT.COLOR_WHITE));
gc.setBackground(composite.getDisplay().getSystemColor(SWT.COLOR_BLUE));
gc.fillGradientRectangle(0, 0, 1, rect.height, true);
gc.dispose();
composite.setBackgroundImage(newImage);

Am i missing something here? Or is it simply not possible without overwriting or extending something (if so what?)? I also tried using the same backgroundImage as another Composite has it, where it works fine.

Thank you for answers!

turns out the problem was not the FigureCanvas itself but GEF which overwrote it somewhere else.
