Set Keyboard cursor position in Combo [message #445721]

Hi all
In my editable(DROP_DOWN but not READ_ONLY) Combo widget, I have a list
of values. The user can also choose to enter a value. When the user
enters this value, I want to force it to start with "0x". I catch the
Modify Event (ModifyListener) and call setText("0x") on the Combo.

The problem is that the keyboard cursor is located before "0x" rather
than at the end of it, which is what I want. Is there a function I could
call to set the Keyboard Cursor after a certain character or at the end
of the text? I went through SWT API and I could not find a method to do
that. I searched Google but that didn't help.

The only solution I could think of was to simulate a SWT.END KeyEvent
which would put the cursor at the end. I tried writing something but
that code did not work (actually I don't know how that code would look
like). I could post what I have and ask questions about it, if that is
the only solution. Is there any method in the API that I might have
looked over or is the simulated Keyevent the best solution?

Thanks in advance.

You should be able to call Combo.setSelection(Point) to position the cursor.
