float LineSpacing ( ) const

inline

Returns: the linespacing for the text object.

void LockCellSize ( bool lock )

Sets whether or not the cell size is locked while in stretch to fit mode. If locked, changing other attributes will not affect the cell size, but the box size instead. If not locked, changing certain attributes, eg. border, will affect the cell size.

Parameters

lock	true to lock cell size, false otherwise

bool LockCellSize ( ) const

inline

Returns: the setting of lock cell size.

virtual bool RequiresFontFile ( ) const
