public void onMouseMove(Widget source, int x, int y) {
if (dragging) {
// System.out.println("MOUSE MOVE:" + x + "," + y);
AbsolutePanel rootPanel = getAbsoluteWidgetPanel(dragWidget);
int newX = x + dragWidget.getAbsoluteLeft() - xOffset;
int newY = y + dragWidget.getAbsoluteTop() - yOffset;
int rootOffsetY = newY - rootPanel.getAbsoluteTop();
int rootOffsetX = newX-rootPanel.getAbsoluteLeft();
if (rootOffsetX < 0) {
rootOffsetX = 0;
}
if (rootOffsetY < 0) {
rootOffsetY = 0;
