116 | [2] | wxFont | |
117 | [3] | -> wxPen | |
118 | ||
119 | The handle table works as follows. | |
120 | When a GDI object is created whilst reading in the | |
121 | metafile, the (e.g.) createpen record is added to the | |
122 | first free entry in the handle table. The createpen | |
123 | record's param1 is a pointer to the actual wxPen, and | |
124 | its param2 is the index into the gdiObjects list, which only | |
125 | grows and never shrinks (unlike the handle table.) | |
126 | ||
127 | When SelectObject(index) is found, the index in the file | |
128 | refers to the position in the handle table. BUT we then | |
129 | set param2 to be the position of the wxPen in gdiObjects, | |
130 | i.e. to param2 of the CreatePen record, itself found in | |
131 | the handle table. | |
132 | ||
133 | When an object is deleted, the entry in the handletable is | |
134 | NULLed but the gdiObjects entry is not removed (no point, and | |
135 | allows us to create all GDI objects in advance of playing the | |
136 | metafile). | |
