这里面包含了一百多个JAVA源文件

This example demonstrates how to convert a coordinate within a component to a coordinate on the screen and visa versa. 
    // Convert a coordinate relative to a component's bounds to screen coordinates
    Point pt = new Point(component.getLocation());
    SwingUtilities.convertPointToScreen(pt, component);
    
    // Convert a coordinate on a screen to a coordinate relative to a component's bounds
    SwingUtilities.convertPointFromScreen(pt, component);
