[news.eclipse.tools] Re: Selection event for SWT Combo text

["Veronika Irvine" <veronika_irvine@xxxxxxx>]

1) CCombo is recomended when you are using a combo box in a table or tree
editor because it is more flexible with regard to resizing than the native
Windows combo box.  However, apart from the editor case, you should really
use the SWT Combo widget because this will give you the native look and
feel.

2) CCombo will not give you a selection event when you select text in the
text widget (same as Combo).  In addition both Combo
and CCombo do not have API to get the text selected in the text widget.  In
the context of a combo box, selection refers to the selection of an item
from the list and does not refer to the selection of text in the text
widget.  There is no direct access to the underlying text widget.

The SWT Combo widget provides cut, copy and paste behaviour by default if
the application does not already handle these accelerators.
