    • 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
      y - the y coordinate to draw the text at
      Throws:
      NullPointerException - if the specified g is null
      Since:

    • 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 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:

    • 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:

    • 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:
      NullPointerException - if the specified fm is null
