Java- how do I increment a variable whenever a file selected in JList?

Question

What I'm having problems with is that I have a list of 10 files in a JList. On a JButton, I have "attached file(s) 0." What I'm trying to achieve is when a user clicks on a file in the JList, the variable fileCount (represents the '0') will increment. Here is the code:

@Override
public void mouseClicked(MouseEvent arg0) {
        int idx = list_fileListing.getSelectedIndex();
        String eFiles[] = ig.getListOfFiles();

       if(idx == list_fileListing.getSelectedIndex()){
    fileCount++;
    }
}

Basically, if a file is selected, increment fileCount. Any suggestions as to how to accomplish this?

Answer 1

The JButton class has a setText() method like many of the other Swing component classes. You can use this method to overwrite the text that is currently on the JButton .

ex:

if(idx == list_fileListing.getSelectedIndex())
{
    fileCount++;
    yourButtonName.setText("attached file(s) " + fileCount);
}

hope this helps.
