Problem whith newline in JTextPane

[Mathias Nilsson]

Hi!

I have a keyListener that checks if the user presses the return key

public void KeyTyped( KeyEvent ke ){
  if( ke.getKeyChar() == KeyEvent.VK_ENTER ){
     // do something
  }
}

this works fine. If the if statement returns true I check to see if I'm in a <ul><li></li></ul> tag.
if the user presses return when in a <li></li> it should append a new <li></li>

I do this by adding the following code

public void KeyTyped( KeyEvent ke ){
  if( ke.getKeyChar() == KeyEvent.VK_ENTER ){
     if( inElement( HTML.Tag.LI ) ){
 
      caretPos = m_jtextpane.getCaretPosition();
       // get the UL element
        Element ep = m_doc.getParagraphElement(  caretPos ).getParentElement();
        try{
          m_doc.insertAfterEnd( ep , "<li></li>" );
          m_jtextpane.setCaretPosition( caretPos + 1 );
        }catch(  Exception ex ){
 
        }
 
    }
  }
}

this code works but not as expected. I get a new line between the <li> elements and I want to remove this \n line. How can I do this?

Total guess - have you tried consuming the KeyEvent?

if( ke.getKeyChar() == KeyEvent.VK_ENTER ){
if( inElement( HTML.Tag.LI ) ){
..... code .....
ke.consume();
}
}

Worth a shot!

That would be it I'm sure. The JTextPane receives the event still and inserts a new line. Consuming the event will put a stop to that.

Thanks, but that didn't help. It still is a line between the <li></li> and the next </li></li>

looks like this if we view the HTML source

<ul>
  <li>
  
 
  </li>
  <li>
      this is a test line
 
  </li>
</ul>

If i go intor the source and remove the \n line then the code will produce 2 dots in the WISWYG editor( when viewing the text in the JTextPane without seeing the HTML tags ) every time i hit the return but when I view the html source it's just 1 <li></li> ??

here is the javacode that handles the

public void keyTyped(KeyEvent ke){
if (ke.getKeyChar() == KeyEvent.VK_ENTER){
System.out.println( "We pressed enter" );


// kolla om vi �r i en li
if( checkParentElementType( HTML.Tag.LI ) ){


int caretPos = m_editor.getCaretPosition();
Element ep = m_doc.getParagraphElement( caretPos ).getParentElement();

try {


ke.consume();
m_doc.insertAfterEnd(ep, "<li></li>");
m_editor.setCaretPosition(caretPos + 1 );

}
catch (Exception ex) {
ex.printStackTrace();
}

}


}

Element elem =  m_doc.getParagraphElement(m_editor.getCaretPosition());
int so = elem.getStartOffset();
int eo = elem.getEndOffset();

try{
System.out.println(  m_editor.getText(so,eo-so).toString().length() );

}catch( Exception ex){
 
}

}

and here is the check method

public boolean checkParentElementType( HTML.Tag tag ){
int p = m_editor.getCaretPosition();
Element e = m_doc.getParagraphElement(p);
String tagString = tag.toString();
if(e.getName().equalsIgnoreCase(tagString))
{
return true;
}
do
{
if((e = e.getParentElement()).getName().equalsIgnoreCase(tagString))
{
return true;

}
} while(!(e.getName().equalsIgnoreCase("html")));
return false;
}

really hope you can help me

After some testing I put the code in the keyPressed method instead of the keyTyped method and the consume() method worked?

Is this the right way to do it or is there a muh better solution?
