|

44 | 11993 | cesar | * <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 | 6880 | cesar | *
|
50 | 11993 | cesar | * <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 | 6880 | cesar | *
|
58 | 11993 | cesar | * <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.
