Detailed Description

TObject is the starting point for much of TVision's class hierarchy. It has no parents but many descendants. Apart from TPoint and TRect, most of TVision's standard classes are ultimately derived from TObject.

Any object that uses TVision's stream facilities must trace its ancestry back to TObject.

Member Function Documentation

void TObject::destroy ( TObject * o ) [inline, static]

Destroys the object pointed by `o'. destroy() deletes an object `o' of a type derived from TObject; that is, any object created with operator new(). destroy() terminates the object, correctly freeing the memory that it occupies. It calls `o->shutDown()' and after does `delete o'. See also: shutDown Definition at line 65 of file tvobjs.h.

void TObject::shutDown ( ) [virtual]

Releases TObject resources. Used internally by TObject::destroy() to ensure correct destruction of derived and related objects. shutDown() is overridden in many classes to ensure the proper setting of related data members when destroy is called. Does nothing. See also: destroy Reimplemented in TDeskTop, TProgram, TLabel, THistory, TEditor, TFileEditor, TFileDialog, TChDirDialog, TNSCollection, TView, TScroller, TListViewer, TGroup, and TWindow. Referenced by destroy().
