- 
drawStringDraw a string with the graphicsgat location (x,y) just likeg.drawStringwould. The first occurrence ofunderlineCharin 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
 
- 
drawStringUnderlineCharAtpublic static void drawStringUnderlineCharAt(Graphics g, String text, int underlinedIndex, int x, int y) Draw a string with the graphicsgat location (x,y) just likeg.drawStringwould. The character at indexunderlinedIndexin text will be underlined. Ifindexis beyond the bounds oftext(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
- Since:
- 1.4
 
- 
drawDashedRectDraws dashed rectangle.- Parameters:
- g- an instance of- Graphics
- x- an X coordinate
- y- an Y coordinate
- width- a width of rectangle
- height- a height of rectangle
 
- 
getPreferredButtonSizeReturns 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
 
- 
drawStringDraws 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
- y- the y coordinate to draw the text at
- Throws:
- NullPointerException- if the specified- gis- null
- Since:
- 9
 
- 
drawStringUnderlineCharAtpublic 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 underlinedIndexparameter 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 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- gis- null
- Since:
- 9

getClippedStringpublic 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 nullor empty
- Throws:
- NullPointerException- if the specified- fmis- null
- Since:
- 9

getStringWidthReturns the width of the passed in string using text properties and anti-aliasing hints from the provided component. If the passed string isnull, 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
         nullstring
- Throws:
- NullPointerException- if the specified- fmis- null
- Since:
- 9
