Documentation is very thin for this - we had to experiment for quite a while to get what we wanted, but it works well. Start by looking at the documentation for
NativeImage
first.
The example code is the most helpful. There are examples in DG_Test in the functions
DrawMyPict
and
OwnerDrawnListBoxPalette::UpdateTab1
. Also possibly
UserItemDialog.cpp
in the example Override_Test.
