从JTextPane获取特定样式的所有文本

Question

I have a JtextPane that has style1 , style2 etc. I want to retrieve all text that is in the textPane that has been inserted with style1 .

Is there a way to do this?

EDIT What I'm trying to accomplish:

I have a client that receives different MessageTypes from the server. I have a "debugging" window that logs each message to the JTextPane. The window has a set of JRadioButtons corresponding to each type of message. The user can check off the buttons to see specific types of messages that were sent from the server.

Answer 1

You can define your own attribute and place it with all the other ones. Just use SimpleAttributeSet and place there the new attribute (let's name it "MessageTypeAttribute") the value could be string constants for each required type.

To iterate the Document use getCharacterElement() method. Start from 0 and then move to the end offset of the element to retrieve the next one.

Answer 2

Looking at the documentation , you can call getStyle( String stylename ) to get the style of a JTextPane.

You may want to build a method like this to select the text you want

public ArrayList<String> getAllOfOneStyle( String inStyle ){
   ArrayList<String> strAL = new ArrayList<String>(); 
   if( jtextpane_01.getStyle(inStyle) != null ){
      strAL.add( jtextpane_01.getText() );
   }

   // do this for each JTextPane

}
