All Implemented Interfaces:

Serializable

public class PJAFontMetrics

extends FontMetrics

implements Serializable

Pure Java AWT Font Metrics implementation. This class returns the metrics of a given font (name + style + sizes).
From version 1.1, all the font data management moved to the new class PJAFontData to avoid using PJAFontMetrics which extends this class in PJAGraphics code (java.awt.FontMetrics requires awt library to be loaded to call initIDs native method).

Since:

PJA1.0

Method Detail

setFont

protected void setFont(Font font)

Deprecated. As of PJA version 1.1, PJAFontPeer doesn't need it anymore.

Sets the font for this metrics object. This protected method is used to set the font afterwards a PJAFontMetrics object is created or deserialized.

Parameters:

font - The matching font for this metrics.

getLeading

public int getLeading()

java.awt.FontMetrics implementation. Returns the leading of this font.

Overrides:

getLeading in class FontMetrics

public int getAscent()

java.awt.FontMetrics implementation. Returns the ascent of this font.

Overrides:

getAscent in class FontMetrics

See Also:

PJAFontData

getDescent

public int getDescent()

java.awt.FontMetrics implementation. Returns the descent of this font.

Overrides:

getDescent in class FontMetrics

getMaxAscent

public int getMaxAscent()

java.awt.FontMetrics implementation. Returns the max ascent of this font.

Overrides:

charWidth

public int charWidth(int ch)

java.awt.FontMetrics implementation. Returns the char width of the character ch in this font.

Overrides:

charWidth in class FontMetrics

See Also:

PJAFontData

charWidth

public int charWidth(char ch)

java.awt.FontMetrics implementation. Returns the char width of the character ch in this font. (need to override charWidth (char ch) of the class java.awt.FontMetrics to avoid stack overflow in getWidths ())

Overrides:

java.awt.FontMetrics implementation. Returns the string width of a string in this font.

Overrides:

charsWidth in class FontMetrics

See Also:

PJAFontData

getCharPixels

public int[] getCharPixels(char ch)

Deprecated. As of PJA version 1.1, replaced by PJAFontData.getCharPixels ().

Returns the pixels array of the character ch.

See Also:
