dlgitem_set_listtag_extra_image_at
dlgitem_set_listtag_extra_image_at(window, listtag, row, image)
Associates image with the outline list entry row in the outline list listtag in window. The image appears at the front of the list item, just to the right of the leaf image set by the dlgitem_set_default_leaf_image function. If listtag does not refer to an outline list listtag, $ERROR is set and zero (0) is returned. Otherwise, one (1) is returned.
The window parameter is a window identifier. The listtag parameter is an outline list listtag (case sensitive). The row parameter is an offset into listtag (starting from one). The image parameter specifies the ACL Designer image resource to place at the front of the list item.
Example
ret = dlgitem_set_listtag_extra_image_at(win, "Hierarchy", 3, "Padlock")
sets the image for the third item in the outline list item Hierarchy to the Padlock image.
