/**
|
| 44 |
* <p>Interface which should be implemented by those windows
|
| 45 |
* which have an identity in the application. Each
|
| 46 |
* SingletonWindow has an associated model, which identifies
|
| 47 |
* the window, and thus it is not possible to create two
|
| 48 |
* SingletonWindow with the same model.</p>
|
| 49 |
*
|
| 50 |
* <p>For example,
|
| 51 |
* if a window contains a text file, maybe it is not suitable to open
|
| 52 |
* two windows to edit the same file. To accomplish this, the edit
|
| 53 |
* window should implement this interface, and the model associated
|
| 54 |
* with the window will be the path to the text file. Then, if the user
|
| 55 |
* tries to open an already open file, the existing window containing
|
| 56 |
* the file will be shown to the user, instead of opening a new one.</p>
|
| 57 |
*
|
| 58 |
* <p>When opening a new SingletonWindow, the framework works in the
|
| 59 |
* following way: all the already open SingletonWindow are searched to try
|
| 60 |
* to find a window which has the same model as the new one. If such window
|
| 61 |
* is found, it is sent to the foreground and no new window is opened;
|
| 62 |
* otherwise, the new window is shown.
