I'm building a wee eclipse plugin, and am making a composite widget
(ClassMethodSelector) that, once a Class has been selected, uses either a
org.eclipse.swt.widgets.List or Combo to display a set of method names to
be selected (depending on if the user wants multiple or only single
selections, respectively). So, when I go to add the method names to the
method list selector (List or Combo) I would have thought I could cast to
some common IList type interface and use the common 'add' method.
i.e. I want to:
<code>
IList list;
if (SINGLE) list = (IList)comboList;
else if (MULTI) list = (IList)listList;
for (IMethod method: type.getMethods()) {
if (method meets other criteria: e.g. it exists)
list.add(method.getElementName());
}
</code>
They don't share any such interface. Is there a particular reason for
this that I'm missing, or is this a valid thing to be requested? (I'm new
here: first time poster.... I did do a search of the newsgroup before
posting and didn't find any other references to the problem).
It just seems unnecessarily tedious to either rewrite the code for each or
have an extra conditional before adding each method name.
