 XmDropSiteQueryStackingOrder(libraXrmyDrcoaplSli)teQueryStackingOrder(library call)




 NAME    [Toc]    [Back]
      XmDropSiteQueryStackingOrder - A Drag and Drop function that returns
      the parent, a list of children, and the number of children for a
      specified widget

 SYNOPSIS    [Toc]    [Back]
      #include <Xm/DragDrop.h>
      Status XmDropSiteQueryStackingOrder(
      Widget widget,
      Widget *parent_return,
      Widget **child_returns,
      Cardinal *num_child_returns);

 DESCRIPTION    [Toc]    [Back]
      XmDropSiteQueryStackingOrder obtains the parent, a list of children
      registered as drop sites, and the number of children registered as
      drop sites for a given widget. The children are listed in current
      stacking order, from bottom-most (first child) to the top-most (last
      child).  This function allocates memory for the returned data that
      must be freed by calling XtFree.

      widget    Specifies the widget ID. For this widget, you obtain the
                list of its children, its parent, and the number of
                children.

      parent_return
                Returns the widget ID of the drop site parent of the
                specified widget.

      child_returns
                Returns a pointer to the list of drop site children
                associated with the specified widget.  The function
                allocates memory to hold the list.  The application is
                responsible for managing the allocated space.  The
                application can recover the allocated space by calling
                XtFree.

      num_child_returns
                Returns the number of drop site children for the specified
                widget.

      For a complete definition of DropSite and its associated resources,
      see XmDropSite(3).

 RETURN    [Toc]    [Back]
      Returns 0 (zero) if the routine fails; returns a nonzero value if it
      succeeds.
