/* Implementation functions:
* 1. The eagleeye control generates a navigation field based on the view range of the Master Control.
* 2. Click the left button in the eagleeye control to move the widget. The red range will move with the mouse. The view range of the master control will move accordingly based on the location of the red range.
* 3. In the eagleeye control, you can right-click the mouse and drag it to generate a new red range to navigate
* The implementation steps are as follows (combined by multiple examples, write by Booker, 2008.4.12
