Yes. That is quite easy. SWT itself does not include a masked text field, but you can create one easy enough using a verify text listener...

Code: Select all

Text field = new Text(group, SWT.BORDER);
field.addVerifyListener(new VerifyListener() {
    public void verifyText(VerifyEvent e) {
        e.doit = Character.isDigit(e.character);
    }
});

You can check for any characters that you like, so you could also allow periods, dashes, backspaces, etc.

We don't plan to add any enhanced widgets directly to SWT Designer. If we do provide any new SWT widgets, they would be part of an add-on package.

If Eclipse.org decides to add any enhanced text widgets to the SWT base, we would, of course, support them.
