# wxGraphicsContext

### MODULE

wxGraphicsContext

### MODULE SUMMARY

See external documentation: wxGraphicsContext.

### DESCRIPTION

See external documentation: wxGraphicsContext.

This class is derived (and can use functions) from:
wxGraphicsObject

### DATA TYPES

wxGraphicsContext()

  An object reference, The representation is internal and can be changed without notice. It can't be used for comparsion stored on disc or distributed for use on other nodes.
