A feature needed for SWT that is still missing in BButton is a
button typically seen in tool bars, that has a small area (usually
an arrow pointing down) that, when clicked, opens a drop down menu.
I originally thought I would just implement such a button as a
custom view in SWT, but I don't think it is easily possible to do
that in a BButton subclass, so I'd probably end up copying and
modifying the BButton code instead. Since there are already
BeOS/Haiku applications that use such a tool bar button anyway (e.g.
Pe and Beam) -- apparently also implementing their own class -- I
believe it would make much more sense to add the functionality to
BButton as well.
/A pretty good implementation of that is in the Caya source, named
ToolButton./
