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 nullg
- Graphics to draw the text totext
- String to displayx
- X coordinate to draw the text aty
- 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 nullg
- Graphics to draw the text totext
- String to displayunderlinedIndex
- Index of a character in the string to underlinex
- X coordinate to draw the text aty
- 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 nullg
- Graphics Graphics- Returns:
- the FontMetrics
