getFontMetrics

public static java.awt.FontMetrics getFontMetrics(javax.swing.JComponent c,
                                  java.awt.Graphics g)

Returns the FontMetrics for the current Font of the passed in Graphics. This method is used when a Graphics is available, typically when painting. If a Graphics is not available the JComponent method of the same name should be used.

Callers should pass in a non-null JComponent, the exception to this is if a JComponent is not readily available at the time of painting.

This does not necessarily return the FontMetrics from the Graphics.

参数:

c - JComponent requesting FontMetrics, may be null

g - Graphics Graphics

返回:

the font metrics

getFontMetrics

public static java.awt.FontMetrics getFontMetrics(javax.swing.JComponent c,

                                  java.awt.Font font)

Returns the FontMetrics for the specified Font. This method is used when a Graphics is available, typically when painting. If a Graphics is not available the JComponent method of the same name should be used.

Callers should pass in a non-null JComonent, the exception to this is if a JComponent is not readily available at the time of painting.

This does not necessarily return the FontMetrics from the Graphics.

参数:

c - Graphics Graphics

g - the g

font - Font to get FontMetrics for

返回:

the font metrics

stringWidth

public static int stringWidth(javax.swing.JComponent c,
              java.awt.FontMetrics fm,
              java.lang.String string)

Returns the width of the passed in String.

参数:

drawTextAntialiased

public static boolean drawTextAntialiased(boolean aaText)

Returns whether or not text should be drawn antialiased.

参数:

aaText - Whether or not aa text has been turned on for the component.

返回:

Whether or not text should be drawn antialiased.

getGraphics2D

                             int underlinedIndex,
                             int x,
                             int y)

Draws the string at the specified location underlining the specified character.
