Do I manually call the mousePressed(e) method?

public void mousePressed(MouseEvent e) {
        if (notInteresed())
                component.getParent().mousePressed(e);
}

There are two problems with that.

The first is that the coordinates of the mouseEvent are relative to
the component, not the parent.

The second is that, in my scenario, the parent registers a
mouseMotionListener in the press. However, if the original press was
on a component, the parent doesn't get the mouseDrag events
(MOUSE_DRAGGED events are delivered to the Component in which the
mouse button was pressed until the mouse button is released
(regardless of whether the mouse position is within the bounds of the
Component).)
