Try It Out - Printing a Sketch
You should have added the code we saw earlier to the
actionPerformed()
method to handle the
Print
menu item event, and the code to
SketchView
to implement the
Printable
interface that we

java.awt.print
. If you compile and run
Sketcher, you should be able to print a sketch.
On my system, when I select the toolbar button to print, I get the dialog shown below.
