• public static final int ROTATE_DEFAULT

• public static final int ROTATE_LEFT

• public static final int ROTATE_NONE

• public static final int ROTATE_RIGHT

Constructor Detail

• public VTextIcon(java.awt.Component component, java.lang.String label)

  Creates a VTextIcon for the specified component with the specified label. It sets the orientation to the default for the string

  See Also:

  verifyRotation

• public VTextIcon(java.awt.Component component, java.lang.String label, int rotateHint)

  Creates a VTextIcon for the specified component with the specified label. It sets the orientation to the provided value if it's legal for the string

  See Also:

  verifyRotation

Method Detail

• public int getIconHeight()

  Returns the icon's height.

  Returns:

  an int specifying the fixed height of the icon.

• public int getIconWidth()

  Returns the icon's width.

  Returns:

  an int specifying the fixed width of the icon.

• public void paintIcon(java.awt.Component c, java.awt.Graphics g, int x, int y)

  Draw the icon at the specified location. Icon implementations may use the Component argument to get properties useful for painting, e.g. the foreground or background color.

• public void propertyChange(java.beans.PropertyChangeEvent e)

  Checks for changes to the font on the fComponent so that it can invalidate the layout if the size changes

• public void setLabel(java.lang.String label)

  sets the label to the given string, updating the orientation as needed and invalidating the layout if the size changes

  See Also:

  verifyRotation

• public static int verifyRotation(java.lang.String label, int rotateHint)

  verifyRotation

  returns the best rotation for the string (ROTATE_NONE, ROTATE_LEFT, ROTATE_RIGHT)

  This is public static so you can use it to test a string without creating a VTextIcon

  from http://www.unicode.org/unicode/reports/tr9/tr9-3.html When setting text using the Arabic script in vertical lines, it is more common to employ a horizontal baseline that is rotated by 90 % counterclockwise so that the characters are ordered from top to bottom. Latin text and numbers may be rotated 90 % clockwise so that the characters are also ordered from top to bottom.

  Rotation rules - Roman can rotate left, right, or none - default right (counterclockwise) - CJK can't rotate - Arabic must rotate - default left (clockwise)

  from the online edition of _The Unicode Standard, Version 3.0_, file ch10.pdf page 4 Ideographs are found in three blocks of the Unicode Standard... U+4E00-U+9FFF, U+3400-U+4DFF, U+F900-U+FAFF

  Hiragana is U+3040-U+309F, katakana is U+30A0-U+30FF

  from http://www.unicode.org/unicode/faq/writingdirections.html East Asian scripts are frequently written in vertical lines which run from top-to-bottom and are arrange columns either from left-to-right (Mongolian) or right-to-left (other scripts). Most characters use the same shape and orientation when displayed horizontally or vertically, but many punctuation characters will change their shape when displayed vertically.

  Letters and words from other scripts are generally rotated through ninety degree angles so that they, too, will read from top to bottom. That is, letters from left-to-right scripts will be rotated clockwise and letters from right-to-left scripts counterclockwise, both through ninety degree angles.

  Unlike the bidirectional case, the choice of vertical layout is usually treated as a formatting style; therefore, the Unicode Standard does not define default rendering behavior for vertical text nor provide directionality controls designed to override such behavior
