public void setImageIndex( int value )
value
Set to the zero-based index within an ImageList object of the image that appears next to this node when it is selected. Returns -1 if the imageIndex property of the node has never been explicitly set and the image that appears next to the node is specified in the TreeView.setImageIndex property of the tree view control that contains this node.
If you have set the selectedImageIndex property of this node or of the tree view control that contains this node to a different image, that image will appear next to the node when the node is selected.
