Subject: Added a typemap that converts the references returned for some GDI
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/d19a83a5ac67c97c208e28289bbf4adaee6b4134

Added a typemap that converts the references returned for some GDI
objects (Brush, Pen, Font, etc.) into copies, (taking advantage of the
copy-on-write capabilities of the C++ class.)  This is to work around
an issue where getting a GDI object changing it and setting it back to
the DC would trigger an incorrect optimization.
