Interface Printable

public abstract interface Printable

The Printable interface is implemented by the print methods of the current page painter, which is called by the printing systemto render a page. When building a Pageable, pairs of PageFormat instances and instances that implement this interface are used to describe each page. The instance implementing Printable is called to print the page's graphics.

Method Detail

print

public int print(Graphics graphics,
                 PageFormat pageFormat,
                 int pageIndex)
          throws PrinterException

Prints the page at the specified index into the specified Graphics context in the specified format. A PrinterJob calls the Printable interface to request that a page be rendered into the context specified by graphics. The format of the page to be drawn is specified by pageFormat. The zero based index of the requested page is specified by pageIndex. If the requested page does not exist then this method returns NO_SUCH_PAGE; otherwise PAGE_EXISTS is returned. The Graphics class or subclass implements the PrinterGraphics interface to provide additional information. If the Printable object aborts the print job then it throws a PrinterException.

Parameters:

graphics - the context into which the page is drawn

pageFormat - the size and orientation of the page being drawn

pageIndex - the zero based index of the page to be drawn

Returns:

PAGE_EXISTS if the page is rendered successfully or NO_SUCH_PAGE if pageIndex specifies a non-existent page.

Throws:

PrinterException - thrown when the print job is terminated.
