      • 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
