Class FontManager

java.lang.Object

se.entra.phantom.client.FontManager

public class FontManager
extends Object

The font manager keeps a cache of the different fonts used by controls. It also supports font substitution.

The following fonts are used on the client. Font index 0 is the default font.

   Java name      Index   Windows        OS/2
   -------------  ------  -------------  ---------------------------
   Dialog           0     System         System Proportional
   Monospaced       1     Courier New    Courier
   SansSerif        2     MS Sans Serif  Helv
   Serif            3     MS Serif       Tms Rmn
   Monospaced       4     Fixedsys       System Monospaced
   Monospaced       5     Terminal       System VIO
   Dialog           6     System         System Proportional Non-ISO
 

The Java fonts may not exist, so the following table maps the names to other fonts when the client is started:

   Name         Alternate(s)
   -----------  ---------------------------------
   Dialog       DialogInput, SansSerif, Helvetica
   Monospaced   Courier
   SansSerif    Helvetica
   Serif        TimesRoman
 

The font substitution is done on the Server in the "server.ini" file under the section [FontSubstitution].

Each font substitution is done with the point size, a space, and the font index (0-6). After the equal sign, specify point size, a space and then font name. Several such font entries may be specified separated by a comma. The client will try to find the matching font, and if found this one will be used instead of the normal font.

Field Detail

DEFAULT

public static Font DEFAULT

The default font.

Method Detail

getFont

public static Font getFont(int index)

Gets a font from the cache or creates one.

getFontHeightOffset

public static int getFontHeightOffset(int index)

Get font substitution font height offset.

getBGFont

public static Font getBGFont(int index)

Returns the correct font for the Business Graphics (BG) control.

getFontHeight

public static int getFontHeight(FontMetrics fm)

Gets the font height. This method makes JDK 1.1 and 1.2 (or better) have the same sizes as the one in JDK 1.1.

getFontAscent

public static int getFontAscent(FontMetrics fm)

Gets the font ascent. This method makes JDK 1.1 and 1.2 (or better) have the same sizes as the one in JDK 1.1.

getFontDescent

public static int getFontDescent(FontMetrics fm)

Gets the font descent. This method makes JDK 1.1 and 1.2 (or better) have the same sizes as the one in JDK 1.1.

getLowerCaseAverageCharWidth

public static int getLowerCaseAverageCharWidth(FontMetrics fm)

Computes the dialog average character width that Phantom uses as dialog coordinates.

This value is taken from the string "abcdefghijklmnopqrstuvwxyz 0123456789" average.

resetFonts

public static void resetFonts()

Reset the font substitution.

substituteFonts

public static void substituteFonts(Phantom phantom,
                   Transaction trans)

Sets up the font substitution

getAllFontMetrics

public static void getAllFontMetrics(Transaction t)

Adds the entire font metrics

setFontRatio

public static void setFontRatio(int xRatio,
                int yRatio,
                boolean useRatioScaling)

Sets the ratio processing for fonts.
