106 Handle table gdiObjects
107 ------------ ----------
109 [1]----param2--- wxBrush
113 The handle table works as follows.
114 When a GDI object is created whilst reading in the
115 metafile, the (e.g.) createpen record is added to the
116 first free entry in the handle table. The createpen
117 record's param1 is a pointer to the actual wxPen, and
118 its param2 is the index into the gdiObjects list, which only
119 grows and never shrinks (unlike the handle table.)
121 When SelectObject(index) is found, the index in the file
122 refers to the position in the handle table. BUT we then
123 set param2 to be the position of the wxPen in gdiObjects,
124 i.e. to param2 of the CreatePen record, itself found in
127 When an object is deleted, the entry in the handletable is
128 NULLed but the gdiObjects entry is not removed (no point, and
129 allows us to create all GDI objects in advance of playing the
