Detailed Description

Window Device Context.

The Window Device Context allows drawing into an FXDrawable, such as an on-screen window (FXWindow and derivatives) or an off-screen image (FXImage and its derivatives). Because certain hardware resources are locked down, only one FXDCWindow may be locked on a drawable at any one time.

The documentation for this class was generated from the following file:
