IWS assigns a unique identification number (ID#) to every object on the screen. These ID#s always start at zero and range up to the total number of objects on the screen. You can click on an object to display its ID# in the status bar.
IWS uses ID#s to determine whether an object displays in front of or behind another object on the screen. Objects with lower ID#s display behind objects with higher ID#s.Use the following object layer tools to move selected object(s) behind or in front of another screen object(s).
Click the Move backward tool to move the selected object or group one layer below the next object on the screen. (Alternatively, right-click on the object and select Move backward from the shortcut menu.) IWS assigns the selected object the next available ID# less than the object behind which it was moved.
Click the Move forward tool to move the selected object or group one layer above the next object on the screen. (Alternatively, right-click on the object and select Move forward from the shortcut menu.) IWS assigns the selected object the first available ID# greater than the object in front of which it was moved.
