RE: [platform-swt-dev] Text widget Listeners

[Mike Wilson <Mike_Wilson@xxxxxxxxxx>]

Please take this discussion off of the
developer's mailing list. This list is for use by the SWT developers to
communicate details of the implementation work amongst themselves. In future,
use the eclipse news groups for asking user questions.

Another approach:

                
text.addKeyListener(new KeyListener() {
                
                 public
void keyPressed(KeyEvent e) {
                
                 
               
if(e.character == '\r' || e.character == '\n')
                
                 
               
                 doSomethingUseful(text.getText());
                
                 }
                
                 ...

I don't think the Text widget appends the '\n' or '\r' characters to its
text property but I am not positive.
