Description
Each item in a tree-view control can have up to four images associated with it.
- An image, such as an open folder, displayed when the item is selected.
- An image, such as a closed folder, displayed when the item is not selected.
- An overlay image that is drawn transparently over the selected or non-selected image.
- A state image: an additional image displayed to the left of the selected or non-selected image. You can use state images, such as checked and cleared check boxes, to indicate application-defined item states.
Use this property to get the index of the overlay image. To obtain the image for a non-selected item, selected item or state image, use the Image, SelectedImage and StateImage properties respectively.
