You will use the
TextLayout
class in the implementation of the
print()
method.
The name of the sketch to print on the cover page is passed to the
SketchCoverPage
constructor. Because
the need has come up, you should add a
getSketchName()
method to the
SketcherFrame
class that sup-
plies a reference to a
String
object containing the file name:
// Method to return the name of the current sketch
public String getSketchName() {
return currentSketchFile == null ? DEFAULT_FILENAME.toString() :
currentSketchFile.getFileName().toString();
}

You can use this method when you create a
SketchCoverPage
object. The
print()
method in the
SketchCoverPage
class needs to recognize when it is being called to print the first page — that is, when
the page index is zero — and then print the cover page. You could do whatever you like here to produce
a fancy cover page, but I'm just putting the code to draw a line border inset from the page and put the
sketch file name in the middle in a box. Here's how you could do that:
public int print(Graphics g,
PageFormat pageFormat,
int pageIndex)
throws PrinterException {
