Digital Dash Documentation, Part 8: Torque Overlay Handling

This is the last profile (at least on the tablet) that I need to describe.  This one simply handles showing the four main overlay scenes when Torque is in the foreground, and removing them when it loses focus.

Profile: V3_TorqueOverlay (342)
Application: Torque
State: Variable Value [ %V3_DrivingMode Set ]
Enter: V3_ShowMainOverlay (340)

A very simple profile.  Whenever we are in the system (i.e. %V3_DrivingMode is SET) and Torque comes to the foreground, we show the four overlay screens.  When Torque loses focus (i.e. we switch to another app) the scenes are hidden. 

A1: Show Scene [ Name:V3_TopMain Display As:Overlay, Blocking Horizontal Position:100 Vertical Position:0 Animation:System Show Exit Button:Off Continue Task Immediately:On ]
A2: Show Scene [ Name:V3_LH Display As:Overlay, Blocking Horizontal Position:4 Vertical Position:196 Animation:System Show Exit Button:Off Continue Task Immediately:On ]
A3: Show Scene [ Name:V3_Bottom Display As:Overlay, Blocking Horizontal Position:100 Vertical Position:200 Animation:System Show Exit Button:Off Continue Task Immediately:On ]
A4: Show Scene [ Name:V3_RH Display As:Overlay, Blocking Horizontal Position:200 Vertical Position:200 Animation:System Show Exit Button:Off Continue Task Immediately:On ]

The entry task just shows the previously created scenes.  All of them are blocking overlays because they all contain elements that the user can interact with.

Exit: V3_HideMainOverlay (341)
A1: Hide Scene [ Name:V3_TopMain Animation:None Continue Task After Error:On ]
A2: Hide Scene [ Name:V3_TopSources Animation:None Continue Task After Error:On ]
A3: Hide Scene [ Name:V3_TopEQ Animation:None Continue Task After Error:On ]
A4: Hide Scene [ Name:V3_CancelOverlays Animation:None Continue Task After Error:On ]
A5: Hide Scene [ Name:V3_LH Animation:None Continue Task After Error:On ]
A6: Hide Scene [ Name:V3_Bottom Animation:None Continue Task After Error:On ]
A7: Hide Scene [ Name:V3_FavoriteSongs Animation:None Continue Task After Error:On ]
A8: Hide Scene [ Name:V3_Destinations Animation:None Continue Task After Error:On ]
A9: Hide Scene [ Name:V3_RH Animation:None Continue Task After Error:On ] 

For the exit task, I took what my father would call the "brute force and awkwardness" approach.  That is, I don't check to see what scenes might be showing and selectively hide them; instead, I just hide any scene that could possibly be showing.  The "Continue Task After Error" lets that happen.
