| class MCoeControlBackground |
Interface to be used if a control elects to be a background drawer.
Parent controls can elect to take responsibility for drawing the background for their child controls. To achieve this, they should aggregate an object that implements this interface. CCoeControl::SetBackground() accepts the object and sets it as the background drawer

Draw the background for a given control. The text drawer that shall be used to draw text on the specific background can be fetched through the GetTextDrawer() method.
| CWindowGc & aGc | Graphics context used for drawing |
| const CCoeControl & aControl | The control being drawn (may be a child of the drawer) |
| const TRect & aRect | The area to be redrawn |
| IMPORT_C void | GetTextDrawer | ( | CCoeTextDrawerBase *& | aTextDrawer, |
| const CCoeControl * | aDrawingControl | |||
| ) | const [virtual] | |||
This function retrieves the text drawer associated with the background.
| CCoeTextDrawerBase *& aTextDrawer | The text drawer associated with the background. This may be null. The default implementation always sets this to 0. |
| const CCoeControl * aDrawingControl | The control that is requesting the text drawer. |
