.SH NAME
wxBufferedDC \- 
  A helper device context for double buffered drawing.
 
.SH DESCRIPTION

  


   This simple class provides a simple way to avoid flicker: when drawing on it,
   everything is in fact first drawn on an in-memory buffer (a
   wxBitmap
   ) and then copied to the screen only once, when this object is destroyed.
  
  


   It can be used in the same way as any other device context. wxBufferedDC
   itself typically replaces
   wxClientDC
   , if you want to use it in your
   OnPaint()
   handler, you should look at
   wxBufferedPaintDC
   .

.SS  wxBufferedDC ()

.SS  wxBufferedDC (wxDC *dcconst wxSize& areaint style = wxBUFFER_CLIENT_AREA)

.SS  wxBufferedDC (wxDC *dcconst wxBitmap& bufferint style = wxBUFFER_CLIENT_AREA)

     


      If you use the first, default, constructor, you must call one of the
      Init
      methods later in order to use the object.
     
     


      The other constructors initialize the object immediately and
      Init()
      must not be called after using them.
     
    
   
  
.SS void Init (wxDC *dcconst wxSize& areaint style = wxBUFFER_CLIENT_AREA)

.SS void Init (wxDC *dcconst wxBitmap& bufferint style = wxBUFFER_CLIENT_AREA)

     


      These functions initialize the object created using the default
      constructor. Please see
      constructors documentation
      for details.
