-
- There are two mechanisms in recent versions of wxWidgets which make the
- pen list less useful than it once was. Under Windows, scarce resources
- are cleaned up internally if they are not being used. Also, a referencing
- counting mechanism applied to all GDI objects means that some sharing
- of underlying resources is possible. You don't have to keep track of pointers,
- working out when it is safe delete a pen, because the referencing counting does
- it for you. For example, you can set a pen in a device context, and then
- immediately delete the pen you passed, because the pen is 'copied'.
-
- So you may find it easier to ignore the pen list, and instead create
- and copy pens as you see fit. If your Windows resource meter suggests
- your application is using too many resources, you can resort to using
- GDI lists to share objects explicitly.
-
- The only compelling use for the pen list is for wxWidgets to keep
- track of pens in order to clean them up on exit. It is also kept for
- backward compatibility with earlier versions of wxWidgets.
