Detailed Description

Device contexts are surfaces that may be drawn on, and provide an abstraction that allows parameterisation of your drawing code by passing different device contexts.

class	wxBufferedDC
	This 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, using the associated wxDC, only once, when this object is destroyed. More...
class	wxAutoBufferedPaintDC
	This wxDC derivative can be used inside of an EVT_PAINT() event handler to achieve double-buffered drawing. More...
class	wxBufferedPaintDC

class	wxMirrorDC
	wxMirrorDC is a simple wrapper class which is always associated with a real wxDC object and either forwards all of its operations to it without changes (no mirroring takes place) or exchanges x and y coordinates which makes it possible to reuse the same code to draw a figure and its mirror -- i.e. More...
