Constructor & Destructor Documentation

TBackground::TBackground ( const TRect & bounds, char aPattern )

Constructor. `bounds' is the bounding rectangle of the background. growMode is set to gfGrowHiX | gfGrowHiY, and the pattern data member is set to `aPattern'.

TBackground::TBackground ( StreamableInit ) [protected]

Constructor. Used to recover the view from a stream. Each streamable class needs a "builder" to allocate the correct memory for its objects together with the initialized virtual table pointers. This is achieved by calling this constructor with an argument of type StreamableInit.
