class | wxAutoBufferedPaintDC
| This wxDC derivative can be used inside of an `EVT_PAINT()` event handler to achieve double-buffered drawing. More...
class | wxBufferedPaintDC

class | wxPaintDC
| A wxPaintDC must be constructed if an application wishes to paint on the client area of a window from within an EVT_PAINT() event handler. More...
class | wxClientDC

| wxGCDC is a device context that draws on a wxGraphicsContext. More...
class | wxMemoryDC

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...
