To use overlay images in a list-view control:
A) Call the
ImageList_SetOverlayImage function to assign an overlay image index to an image in the full-sized and small icon image lists. An overlay image is identified by a one-based index.
B) You can associate an overlay image index with an item when you call the
ListView_InsertItem or
ListView_SetItem macro. Use the
INDEXTOOVERLAYMASK macro to specify an overlay image index in the state member of the item's
LVITEM structure. You must also set the
LVIS_OVERLAYMASK bits in the
stateMask member.
