Fields§

§dev: pDevDesc

Stuff that the devices can see (and modify). All detailed in GraphicsDevice.h

§displayListOn: Rboolean

toggle for display list status

§displayList: SEXP

display list

§DLlastElt: SEXP

A pointer to the end of the display list to avoid traversing pairlists

§savedSnapshot: SEXP

The last element of the display list just prior to when the display list was last initialised

§dirty: Rboolean

Has the device received any output?

§recordGraphics: Rboolean

Should a graphics call be stored on the display list? Set to FALSE by do_recordGraphics, do_dotcallgr, and do_Externalgr so that nested calls are not recorded on the display list

§gesd: [*mut GESystemDesc; 24]

Stuff about the device that only graphics systems see. The graphics engine has no idea what is in here. Used by graphics systems to store system state per device.

§ask: Rboolean

per-device setting for ‘ask’ (use NewFrameConfirm)

§appending: Rboolean

Is a device appending a path ?
