Copying graphics contexts

Copy graphics context attributes to another GC using copyGC:dest:. The following example creates a GC, sets its foreground and background attributes, and then copies these attributes to a new GC.

| oldGC newGC |

oldGC := CgWindow default

createGC: None

values: nil.

oldGC

setForeground: CgWindow default blackPixel;

setBackground: CgWindow default whitePixel.

newGC := CgWindow default

createGC: None

values: nil.

oldGC

copyGC: GCForeground | GCBackground

dest: newGC
