Example 2: An IlvDocument with a Flow of Text

INDEX

PREVIOUS NEXT

Here is a second example that creates a document and fills it with text. This example uses the IlvFlow class instance associated with a document to set the text.

The example shows how to:

create an IlvPrintableDocument, object,
create the IlvFlow object,
add text and image to the IlvFlow object,
set the text style and paragraph alignment,
create and use the printing controller,
and, finally, use the user interface components to preview the document you created.

 // Creates the document.
 IlvPrintableDocument document 
= new IlvPrintableDocument("A Test Document");
   
// Gets the flow to add text and images.
IlvFlow flow = document.getFlow();

// Sets the style of text and paragraph alignment
// for the title.
IlvFlow.TextStyle style = new IlvFlow.TextStyle();
style.setFont(new Font("Helvetica", Font.BOLD, 20));
style.setAlignment(IlvFlow.TextStyle.CENTER_ALIGNMENT);
flow.setTextStyle(style);

// Adds the title text.
flow.add("The Printing Framework Document Model");

flow.newLine();

// Sets the style of text for the next paragraph.
style.setAlignment(IlvFlow.TextStyle.LEFT_ALIGNMENT);
style.setFont(new Font("Helvetica", Font.PLAIN, 16));
flow.setTextStyle(style);

flow.newLine();
flow.add("The document model provides a structure to define a multiple-page 
document to be printed. The document model allows you to concentrate your 
efforts on creating your printable document without worrying about how the 
document is previewed and printed. The printing framework previews and prints 
the document for you.");
 
flow.newLine();
flow.newLine();
flow.add("The following figure shows the relationship between the main classes 
in the document model:");
flow.newLine();

try {
  
    // Loads an image to add.
    Image image = 
IlvUtil.GetImageFromFile(Class.forName("demos.print.PrintExample"), 
"model.gif");

    // Adds the image to the flow.
    flow.add(image, IlvFlow.TOP_ALIGNMENT);

  } catch (Exception e) {
}

// Creates the print controller.
IlvPrintingController controller = new IlvPrintingController(document);
    
// Previews the document.
controller.setPreviewMode(IlvPrintPreviewPanel.CONTINUOUS_MODE);
controller.printPreview(JOptionPane.getRootFrame());
