* JFileChooser.java
|
53 |
* <p>JFileChooser that tracks the last visited directory for a given ID. It allows you to
|
54 |
* open the JFileChooser in the same directory where you were the last time you open a file
|
55 |
* in the file system.<br>
|
56 |
* </p>
|
57 |
* <p>
|
58 |
* It needs to specify a string defining the JFileChooser ID in order to know what kind of
|
59 |
* files you are going to open. For example after creating a JFileChooser by doing this:<br>
|
60 |
* <b><code>new JFileChooser("TEMPLATES_FILECHOOSER", defaultDirectory);</code></b><br> each time
|
61 |
* you create another JFileChooser anywhere giving the same ID, it will point directly to
|
62 |
* the last directory where you opened a file using this JFileChooser with an equal ID.
