The handle table works as follows.
When a GDI object is created whilst reading in the
metafile, the (e.g.) createpen record is added to the
record's param1 is a pointer to the actual wxPen, and
its param2 is the index into the gdiObjects list, which only
grows and never shrinks (unlike the handle table.)
-
+
When SelectObject(index) is found, the index in the file
refers to the position in the handle table. BUT we then
set param2 to be the position of the wxPen in gdiObjects,
allows us to create all GDI objects in advance of playing the
metafile).
