Specifies the horizontal spacing (in pixels) between adjacent columns of list view items for list-based list view controls (i.e., where the VIEW-MODE attribute is set to VM-LIST), or the horizontal indentation of a tree view control's items relative to their respective parent. A value of zero is interpreted as "unspecified", implying that the control's default spacing is used.
Note that the spcified value is automatically scaled on control creation, if necessary, if the parent dialog's AUTO-ADJUST attribute is set to TRUE.
