The build in values will be reset to the default ones if the platform is re-set.

Parameters:: unitStrings - The unit strings. E.g. "mu", "myunit". Will be converted to lower case and trimmed. Not null.; x - The value for the horizontal dimension.

See Also:: setButtonOrder(String)

setButtonOrder

public static void setButtonOrder(java.lang.String order)

Sets the order for the typical buttons in a standard button bar. It is one letter per button type.

Letter in upper case will get the minimum button width that the getMinimumButtonWidth() specifies and letters in lower case will get the width the current look&feel specifies.

Gaps will never be added to before the first component or after the last component. However, '+' (push) will be applied before and after as well, but with a minimum size of 0 if first/last so there will not be a gap before or after.

If gaps are explicitly set on buttons they will never be reduced, but they may be increased.

These are the characters that can be used:

'L' - Buttons with this style tag will staticall end up on the left end of the bar.
'R' - Buttons with this style tag will staticall end up on the right end of the bar.
'H' - A tag for the "help" button that normally is supposed to be on the right.
'E' - A tag for the "help2" button that normally is supposed to be on the left.
'Y' - A tag for the "yes" button.
'N' - A tag for the "no" button.
'X' - A tag for the "next >" or "forward >" button.
'B' - A tag for the "< back>" or "< previous" button.
'I' - A tag for the "finish".
'A' - A tag for the "apply" button.
'C' - A tag for the "cancel" or "close" button.
'O' - A tag for the "ok" or "done" button.
'U' - All Uncategorized, Other, or "Unknown" buttons. Tag will be "other".
'+' - A glue push gap that will take as much space as it can and at least an "unrelated" gap. (Platform dependant)
'_' - (underscore) An "unrelated" gap. (Platform dependant)

Even though the style tags are normally applied to buttons this works with all components.

The normal style for MAC OS X is "L_HE+U+FBI_NYCOA_R", for Windows is "L_E+U+FBI_YNOCAH_R", and for GNOME is "L_HE+UNYACBXIO_R".
