wx:dc%

    Superclass:  wx:object%

A  wx:dc% object is a device context onto which graphics and text can be drawn. It represents a number of output devices in a generic way; e.g. a canvas has a device context and a printer also has a device context.

An instance of  wx:dc% cannot be created directly. Instead, instances of  wx:dc% subclasses cn be created, such as  wx:memory-dc%.
