Method Summary public  void bind(Element el)      Binds this TextMetrics instance to an element from which to copy existing CSS styles that can affect the size of the rendered text. public static  TextMetrics get()      Returns the singleton instance. public  int getHeight(String text)      Returns the measured height of the specified text. public  Size getSize(String text)      Returns the size of the specified text based on the internal element's style and width properties. public  int getWidth(String text)      Returns the measured width of the specified text. public  void setFixedWidth(int width)      Sets a fixed width on the internal measurement element. Method Detail bind public void bind(Element el)(Code) Binds this TextMetrics instance to an element from which to copy existing CSS styles that can affect the size of the rendered text. Parameters:   el - the element get public static TextMetrics get()(Code) Returns the singleton instance. the text metrics instance getHeight public int getHeight(String text)(Code) Returns the measured height of the specified text. For multiline text, be sure to call TextMetrics.setFixedWidth if necessary. Parameters:   text - the text to be measured the height in pixels getSize public Size getSize(String text)(Code) Returns the size of the specified text based on the internal element's style and width properties. Parameters:   text - the text to measure the size getWidth public int getWidth(String text)(Code) Returns the measured width of the specified text. Parameters:   text - the text to measure the width in pixels setFixedWidth public void setFixedWidth(int width)(Code) Sets a fixed width on the internal measurement element. If the text will be multiline, you have to set a fixed width in order to accurately measure the text height. Parameters:   width - the width to set on the element Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
