Gets a PrintJob object which is the result of initiating a print operation on the toolkit's platform.

Usage

From source file:JuliaSet2.java

public void print() {
    // Create some attributes objects. This is Java 1.3 stuff.
    // In Java 1.1, we'd use a java.util.Preferences object instead.
    JobAttributes jattrs = new JobAttributes();
    PageAttributes pattrs = new PageAttributes();

    // Set some example attributes: monochrome, landscape mode
    pattrs.setColor(PageAttributes.ColorType.MONOCHROME);
    pattrs.setOrientationRequested(PageAttributes.OrientationRequestedType.LANDSCAPE);
    // Print to file by default
    jattrs.setDestination(JobAttributes.DestinationType.FILE);
    jattrs.setFileName("juliaset.ps");

    // Look up the Frame that holds this component
    Component frame = this;
    while (!(frame instanceof Frame))
        frame = frame.getParent();//  ww  w.  ja  va 2s  .c om

    // Get a PrintJob object to print the Julia set with.
    // The getPrintJob() method displays a print dialog and allows the user
    // to override and modify the default JobAttributes and PageAttributes
    Toolkit toolkit = this.getToolkit();
    PrintJob job = toolkit.getPrintJob((Frame) frame, "JuliaSet1", jattrs, pattrs);

    // We get a null PrintJob if the user clicked cancel
    if (job == null)
        return;

    // Get a Graphics object from the PrintJob.
    // We print simply by drawing to this Graphics object.
    Graphics g = job.getGraphics();

    // Center the image on the page
    Dimension pagesize = job.getPageDimension(); // how big is page?
    Dimension panesize = this.getSize(); // how big is image?
    g.translate((pagesize.width - panesize.width) / 2, // center it
            (pagesize.height - panesize.height) / 2);

    // Draw a box around the Julia Set and label it
    g.drawRect(-1, -1, panesize.width + 2, panesize.height + 2);
    g.drawString("Julia Set for c={" + cx + "," + cy + "}", 0, -15);

    // Set a clipping region
    g.setClip(0, 0, panesize.width, panesize.height);

    // Now print the component by calling its paint method
    this.paint(g);

    // Finally tell the printer we're done with the page.
    // No output will be generated if we don't call dispose() here.
    g.dispose();
}
