Method Detail

drawString

public static void drawString(javax.swing.JComponent c,
                              java.awt.Graphics g,
                              java.lang.String text,
                              int x,
                              int y)

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

Parameters:

c - JComponent that will display the string, may be null

g - Graphics to draw the text to

text - String to display

x - X coordinate to draw the text at

y - Y coordinate to draw the text at

drawStringUnderlineCharAt

public static void drawStringUnderlineCharAt(javax.swing.JComponent c,
                                             java.awt.Graphics g,
                                             java.lang.String text,
                                             int underlinedIndex,
                                             int x,
                                             int y)

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

Parameters:

c - JComponent that will display the string, may be null

g - Graphics to draw the text to

text - String to display

underlinedIndex - Index of a character in the string to underline

x - X coordinate to draw the text at

y - Y coordinate to draw the text at

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.

Parameters:

c - JComponent requesting FontMetrics, may be null

g - Graphics Graphics

Returns:

the FontMetrics
