				e.gc.setForeground(bottomNavigationElementShadowStroke1);
				e.gc.drawLine(0, 1, bounds.width - 2, 1);
				e.gc.setForeground(bottomNavigationElementShadowStroke2);
				e.gc.drawLine(0, 2, bounds.width - 2, 2);
			} else {
				e.gc.setBackground(listBackground);
				e.gc.fillRectangle(0, 0, bounds.width, bounds.height);

			if (isDownScrollRequired()) {
				e.gc.setForeground(widgetDarkShadow);
				int middle = bounds.width / 2;
				int bottom = bounds.height - 3;
				e.gc.drawLine(middle + 1, bottom, middle + 5, bottom - 4);
				e.gc.drawLine(middle, bottom, middle - 4, bottom - 4);
