  • headers/os/interface/Button.h

Subject: [PATCH] Add BButton SetButtonColor and SetLabelColor

Also corrects ticket# 12604

Usage of the new methods requires an active attachment to a window or
view, otherwise the colors will become overridden by the default
AttachedToWindow() logic.  A debugger call is made to make this failure
obvious.

In the future, adding two rgb_color members for the colors will be preferred,
for now there is no ABI room.
