/**
|
48 |
* According to the gvSIG's GUI style sheet all the buttons in the application will
|
49 |
* have a normative size. No smaller than a concrete size, and big enough to contain
|
50 |
* the text and avoiding the "..." characters. The button will grow up in width by
|
51 |
* a set of widths defined in this style sheet, always choosing the smallest width that
|
52 |
* can contain the text. If the biggest width is not enought for this purpose then the
|
53 |
* button will automatically grow up to the smallest necessary width to fit the text.<br>
|
54 |
* <p>
|
55 |
* The button resizing is based on the <b>setText(String txt)</b> method. However,
|
56 |
* it is possible to use a custom size if you invoke one of <b>setSize(..)</b>,
|
57 |
* <b>setBorders(...)</b> or <b>setPreferredSize(...)</b> after invoking the
|
58 |
* <b>setText(...)<b> method.
|
59 |
* <p>
|
60 |
* This class is just a standard javax.swing.JButton that handles this issue.
