Change HTML in JEdtiorPane

Asked by: clivecrawdevil

Hi Experts

I am using JEditiorPane to display HTML I want to be able to change the font and size of the text displayed by the web page. I know this is possible in a JTextArea.

I am using the code below for my ActionListener the code executes but does not have any effect on the web page displayed.

public void actionPerformed(ActionEvent event) {
            //This method is called whenever an event occurs on a component
            //that has registered an ActionListener
            
            //Read the action command
            String c = event.getActionCommand();
            System.out.println(c); //Print the action command for demonstration purposes
            
            if("Font Info".equals(c)){
                  //Show font information
                  String msg =      "Font Name:" + browserPane.getFont().getName()
                                          + "\nFont Size:" + browserPane.getFont().getSize();
                  JOptionPane.showMessageDialog(this, msg, "Font Information", JOptionPane.INFORMATION_MESSAGE);
            }
            else if("New tab".equals(c)){
                  //Create new tab
                  createNewTab();
            }
            else if("Exit".equals(c)){
                  //Exit program
                  System.exit(0);
            }
            else if("Helvetica".equals(c)){
                  //Set the font to Helvetica
                  browserPane.setFont(new Font("Helvetica", Font.PLAIN, browserPane.getFont().getSize()));
            }
            else if("Courier".equals(c)){
                  //Set the font to Courier
                  browserPane.setFont(new Font("Courier", Font.PLAIN, browserPane.getFont().getSize()));
            }
            else{
                  //Resize the font
                  browserPane.setFont(new Font(browserPane.getFont().getName(), Font.PLAIN, Integer.parseInt(c)));
            }
      }
Does anyone know how to manipulate the font and font size of a web page displayed in a JEditorPane?

Thanks

Clive
