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

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...

| This class encapsulates a platform-independent image. More...
class | wxImageList
| A wxImageList contains a list of images, which are stored in an unspecified form. More...
class | wxMetafile
| A wxMetafile represents the MS Windows metafile object, so metafile operations have no effect in X. More...

| A palette is a table that maps pixel values to RGB colours. More...
class | wxPen
| A pen is a drawing tool for drawing outlines. More...
class | wxPenList
| There is only one instance of this class: wxThePenList. More...
class | wxPixelData< Image, PixelFormat >
| A class template with ready to use implementations for getting direct and efficient access to wxBitmap's internal data and wxImage's internal data through a standard interface. More...
class | wxRegionIterator
| This class is used to iterate through the rectangles in a region, typically when examining the damaged regions of a window within an OnPaint call. More...
class | wxRegion
| A wxRegion represents a simple or complex region on a device context or window. More...
struct | wxSplitterRenderParams

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
