Regarding listeners in textarea

[Seema Sharma]

Hi,
I am working for creating help page. After search is done, i get the required texts which are placed in Jtextarea. On clicking each text, respective information page should be displayed in JEditorpane.
Please help me in knowing which listener i can use to click each text.

I have used document listener but not performing what i require.

//Adding document listener
textArea.getDocument().addDocumentListener(this);
 
//Implementing methods
public void changedUpdate(DocumentEvent arg0) {
System.out.println("INSIDE changedUpdate ");
}
 
public void insertUpdate(DocumentEvent arg0) {
System.out.println("INSIDE insertUpdate ");
if(arg0.equals("Global View")){
try {
URL htmlURL = new URL("file:"+strNewPath+"\\img\\First.html");
editor.setPage(htmlURL);
} catch (IOException ex) {
editor.setText("Page could not be loaded");
}
}
}
 
public void removeUpdate(DocumentEvent arg0) {
System.out.println("INSIDE removeUpdate ");
}

Please correct me.

Regards,
Seema

You are comparing DocumentEvents with Strings. That will always yield false.

Also, you may want to know that an insertUpdate event is triggered for every addition to the document. When you're typing, that is one event for each typed character.

On a side note, you may want to look at JSR 97, which is the JavaHelp 2.0 specification. More information and downloads can be found here.
