# ATTR_FIRST_CHILD

Type: | Panel attribute
Description: | The panel handle of the first child panel in the panel you specify. Call GetPanelAttribute with ATTR_NEXT_PANEL on this first child panel handle to obtain the handle of the next sibling panel. On the last child panel, ATTR_NEXT_PANEL returns zero. Use the panel attribute ATTR_NUM_CHILDREN to get the total number of child panels in a panel. Note: If you pass zero for the parent panel, the first top-level panel is returned. You can then use ATTR_NEXT_PANEL to get the next sibling panel.
Restrictions: | Not settable.
