- * the TreeView control should have the extended check-box style set
- * *BEFORE* actually setting the check-box window style, because it is
- * only at that step that the TreeView control builds its image list
- * containing the three check-box states. Indeed, if the extended
- * check-box style was applied after setting the window style, then
- * the image list would be already built with the default two states
- * and would not be updated.
- *
- * The MSDN documentation is not very clear on that point.
- *
- * Let me also take this opportunity to document what those
- * extended check-box state styles look like on Windows Vista+ :
- *
- * - TVS_EX_DIMMEDCHECKBOXES creates a grey tone version of the normal checked box state.
- * - TVS_EX_EXCLUSIONCHECKBOXES creates a red 'X'-style cross check-box state.
- * - TVS_EX_PARTIALCHECKBOXES creates a filled box.
