### drawString

public static void drawString​(Graphics g, String text, int underlinedChar, int x, int y)
Draw a string with the graphics `g` at location (x,y) just like `g.drawString` would. The first occurrence of `underlineChar` in text will be underlined. The matching algorithm is not case sensitive.

Parameters:
  `g` - an instance of `Graphics`
  `text` - a text
  `underlinedChar` - an underlined char
  `x` - an X coordinate
  `y` - an Y coordinate

### drawStringUnderlineCharAt

public static void drawStringUnderlineCharAt​(Graphics g, String text, int underlinedIndex, int x, int y)
Draw a string with the graphics `g` at location (`x`, `y`) just like `g.drawString` would. The character at index `underlinedIndex` in text will be underlined. If `index` is beyond the bounds of `text` (including < 0), nothing will be underlined.

Parameters:
  `g` - Graphics to draw with
  `text` - String to draw
  `underlinedIndex` - Index of character in text to underline
  `x` - x coordinate to draw at
  `y` - y coordinate to draw at

Returns the preferred size of the button.

Parameters:
  `b` - an instance of `AbstractButton`
  `textIconGap` - a gap between text and icon
Returns:
  the preferred size of the button

### drawString

public static void drawString​(JComponent c, Graphics2D g, String string, float x, float y)
Draws the given string at the specified location using text properties and anti-aliasing hints from the provided component. Nothing is drawn for the null string.

Parameters:
  `c` - the component that will display the string, may be null
  `g` - the graphics context, must not be null
  `string` - the string to display, may be null
  `x` - the x coordinate to draw the text at

  `NullPointerException` - if the specified `g` is `null`
Since:
  9

### drawStringUnderlineCharAt

public static void drawStringUnderlineCharAt​(JComponent c, Graphics2D g, String string, int underlinedIndex, float x, float y)
Draws the given string at the specified location underlining the specified character. The provided component is used to query text properties and anti-aliasing hints.

The `underlinedIndex` parameter points to a char value (Unicode code unit) in the given string. If the char value specified at the underlined index is in the high-surrogate range and the char value at the following index is in the low-surrogate range then the supplementary character corresponding to this surrogate pair is underlined.

No character is underlined if the index is negative or greater than the string length `(index < 0 || index >= string.length())` or if the char value specified at the given index is in the low-surrogate range.

Parameters:
  `c` - the component that will display the string, may be null
  `g` - the graphics context, must not be null
  `string` - the string to display, may be null
  `underlinedIndex` - index of a a char value (Unicode code unit) in the string to underline
  `x` - the x coordinate to draw the text at
  `y` - the y coordinate to draw the text at
Throws:
  `NullPointerException` - if the specified `g` is `null`
Since:
  9

  `getStringWidth(javax.swing.JComponent, java.awt.FontMetrics, java.lang.String)`

### getClippedString

public static String getClippedString​(JComponent c, FontMetrics fm, String string, int availTextWidth)
Clips the passed in string to the space provided. The provided component is used to query text properties and anti-aliasing hints. The unchanged string is returned if the space provided is greater than the string width.

Parameters:
  `c` - the component, may be null
  `fm` - the FontMetrics used to measure the string width, must be obtained from the correct font and graphics. Must not be null.
  `string` - the string to clip, may be null
  `availTextWidth` - the amount of space that the string can be drawn in
Returns:
  the clipped string that fits in the provided space, an empty string if the given string argument is `null` or empty
Throws:
  `NullPointerException` - if the specified `fm` is `null`
Since:
  9
See Also:
  `getStringWidth(javax.swing.JComponent, java.awt.FontMetrics, java.lang.String)`

### getStringWidth

public static float getStringWidth​(JComponent c, FontMetrics fm, String string)
Returns the width of the passed in string using text properties and anti-aliasing hints from the provided component. If the passed string is `null`, returns zero.

Parameters:
  `c` - the component, may be null
  `fm` - the FontMetrics used to measure the advance string width, must be obtained from the correct font and graphics. Must not be null.
  `string` - the string to get the advance width of, may be null
Returns:
  the advance width of the specified string, zero is returned for `null` string
Throws:
