Hi All,
I have one JTextArea , JList in a single JSplitPane ....when i enter
the data in TextArea the respective row no will be increased at left side in jlist .....and when i delete one line of Text from the TextArea automatically the row no in jlist need to be removed ....
How to achieve this functionality.....pls help me.
Thanks in advance
If you are just trying to get row numbers for you JTextArea then you should be adding a row header to your JScrollPane. This is done by adding a component to the scroll pane using the setRowHeaderView(...) method. Search the forum for this method and you will find line number components for this purpose.
