Examples of org.eclipse.swt.graphics.GC.fillGradientRectangle()

org.eclipse.swt.graphics.GC.fillGradientRectangle()
Fills the interior of the specified rectangle with a gradient sweeping from left to right or top to bottom progressing from the receiver's foreground color to its background color. @param x the x coordinate of the rectangle to be filled @param y the y coordinate of the rectangle to be filled @param width the width of the rectangle to be filled, may be negative(inverts direction of gradient if horizontal) @param height the height of the rectangle to be filled, may be negative(inverts direction of gradient if vertical) @param vertical if true sweeps from top to bottom, else sweeps from left to right @exception SWTException
- ERROR_GRAPHIC_DISPOSED - if the receiver has been disposed
@see #drawRectangle(int,int,int,int)
