MCoeControlBackground Class Reference

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

IMPORT_C voidGetTextDrawer(CCoeTextDrawerBase *&aTextDrawer,
const CCoeControl *aDrawingControl
)const [virtual]

This function retrieves the text drawer associated with the background.
