com.jgoodies.forms.util.DefaultUnitConverter
| DefaultUnitConverter | | final public class DefaultUnitConverter extends AbstractUnitConverter (Code) | | This is the default implementation of the
UnitConverter interface.
It converts horizontal and vertical dialog base units to pixels.
The horizontal base unit is equal to the average width, in pixels,
of the characters in the system font; the vertical base unit is equal
to the height, in pixels, of the font.
Each horizontal base unit is equal to 4 horizontal dialog units;
each vertical base unit is equal to 8 vertical dialog units.
The DefaultUnitConverter computes dialog base units using a default font
and a test string for the average character width. You can configure
the font and the test string via the bound Bean properties
defaultDialogFont and averageCharacterWidthTestString.
See also Microsoft's suggestion for a custom computation
here.
Since the Forms 1.1 this converter logs font information at
the CONFIG level.

| getAverageCharacterWidthTestString | | public String getAverageCharacterWidthTestString()(Code) | | Returns the string used to compute the average character width.
By default it is initialized to "X".
the test string used to compute the average character width |
| getDefaultDialogFont | | public Font getDefaultDialogFont()(Code) | | Returns the dialog font that is used to compute the dialog base units.
If a default dialog font has been set using
DefaultUnitConverter.setDefaultDialogFont(Font) , this font will be returned.
Otherwise a cached fallback will be lazily created.
the font used to compute the dialog base units |
| getDialogBaseUnitsX | | protected double getDialogBaseUnitsX(Component component)(Code) | | Returns the cached or computed horizontal dialog base units.
Parameters:
component - a Component that provides the font and graphics the horizontal dialog base units |
| getDialogBaseUnitsY | | protected double getDialogBaseUnitsY(Component component)(Code) | | Returns the cached or computed vertical dialog base units
for the given component.
Parameters:
component - a Component that provides the font and graphics the vertical dialog base units |
| getInstance | | public static DefaultUnitConverter getInstance()(Code) | | Lazily instantiates and returns the sole instance.
the lazily instantiated sole instance |
| setAverageCharacterWidthTestString | | public void setAverageCharacterWidthTestString(String newTestString)(Code) | | Sets a string that will be used to compute the average character width.
By default it is initialized to "X". You can provide
other test strings, for example:
- "Xximeee"
- "ABCEDEFHIJKLMNOPQRSTUVWXYZ"
- "abcdefghijklmnopqrstuvwxyz"
Parameters:
newTestString - the test string to be used
throws:
IllegalArgumentException - if the test string is empty
throws:
NullPointerException - if the test string is null |
| setDefaultDialogFont | | public void setDefaultDialogFont(Font newFont)(Code) | | Sets a dialog font that will be used to compute the dialog base units.
Parameters:
newFont - the default dialog font to be set |
