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 | 6140 | jaume | * a set of widths defined in this style sheet, always choosing the smallest width that
|
52 | 6099 | jaume | * can contain the text. If the biggest width is not enought for this purpose then the
|
53 | 6148 | jaume | * button will automatically grow up to the smallest necessary width to fit the text.<br>
|
54 | 6099 | jaume | * <p>
|
55 | 6140 | jaume | * 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.
