class	wxBrushList
	A brush list is a list containing all brushes which have been created. More...
class	wxColour
	A colour is an object representing a combination of Red, Green, and Blue (RGB) intensity values, and is used to determine drawing colours. More...
class	wxCursor
	A cursor is a small bitmap usually used for denoting where the mouse pointer is, with a picture that might indicate the interpretation of a mouse click. More...
class	wxDC
	A wxDC is a "device context" onto which graphics and text can be drawn. More...
class	wxDCClipper
	wxDCClipper is a helper class for setting a clipping region on a wxDC during its lifetime. More...
class	wxDCBrushChanger

class	wxFontList
	A font list is a list containing all fonts which have been created. More...
class	wxFontEnumerator
	wxFontEnumerator enumerates either all available fonts on the system or only the ones with given attributes - either only fixed-width (suited for use in programs such as terminal emulators and the like) or the fonts available in the given encoding). More...
class	wxNativeFontInfo
	wxNativeFontInfo is platform-specific font representation: this class should be considered as an opaque font description only used by the native functions, the user code can only get the objects of this type from somewhere and pass it somewhere else (possibly save them somewhere using ToString() and restore them using FromString()) More...
class	wxColourDatabase
	wxWidgets maintains a database of standard RGB colours for a predefined set of named colours. More...

class	wxImage::RGBValue
	A simple class which stores red, green and blue values as 8 bit unsigned integers in the range of 0-255. More...

class	wxDelegateRendererNative
	wxDelegateRendererNative allows reuse of renderers code by forwarding all the wxRendererNative methods to the given object and thus allowing you to only modify some of its methods – without having to reimplement all of them. More...
class	wxRendererNative
