Icepdf-Viewer how to add default file name and extention when saving PDF file?

[ctoabidmaqbool1]

Hi! I am trying to auto select default .pdf extention in Saving dialog of PDF viewer. Also if it's easily possible give default pdf file name, if user no changed name of saving pdf by user e.g. PersonDetails.pdf.

Currently this is my method to open the icepdf-viewer!

  // Open the generated PDF in the icepdf-viewer
  private void openPdfInViewer(ByteArrayOutputStream outputStream) {
      // Create a SwingController
      SwingController controller = new SwingController();

      // Build a viewer component
      SwingViewBuilder factory = new SwingViewBuilder(controller);

      InputStream is = new ByteArrayInputStream(outputStream.toByteArray());
      controller.openDocument(is, "", "");
      controller.setIsEmbeddedComponent(true);

      // Create the viewer as a JPanel
      controller.getDocumentViewController().setAnnotationCallback(
              new MyAnnotationCallback(controller.getDocumentViewController())
      );

      JPanel viewerComponentPanel = factory.buildViewerPanel();

      // Create JFrame to contain the viewer
      JFrame viewerFrame = new JFrame();
      viewerFrame.getContentPane().add(viewerComponentPanel);
      viewerFrame.pack();
      viewerFrame.setVisible(true);
  }

How can i give the file name and extention?

Sample project for testing: https://github.com/ctoabidmaqbool1/iTextPdf-5-And-ICEpdf-Viewer-Test

Try something like this:
controller.openDocument(is, "", "PersonDetails.pdf");

The save as dialog should show "PersonDetails.pdf" as the file name.

Thanks a lot for trying to helping me!

I alreay have tried this method, still this method not works at all!
e.g. Object Name: is still empty by default and Save as type: is still All types (.)

Another thing, when some one give file name manuely without giving extention and try to save, error happens.

How one can give the default extention e.g. *.pdf?

Weird, I'll load up your sample project and get you a fix.

[pcorless]

This is sort of silly but there is code checking for a file separator delimiter. So the following line works just fine on my Linux box.

controller.openDocument(is, "", "./PersonDetails.pdf");
and expect the folowing would be fine on Windows
controller.openDocument(is, "", "\\PersonDetails.pdf");

Couple suggestions for your test program.

`
private void openPdfInViewer(ByteArrayOutputStream outputStream) {

    // read/store the font cache, just needs to be called once when your app loads. 
    FontPropertiesManager.getInstance().loadOrReadSystemFonts();

    // Create a SwingController
    SwingController controller = new SwingController();

    // Create the viewer as a JPanel
    controller.getDocumentViewController().setAnnotationCallback(
            new MyAnnotationCallback(controller.getDocumentViewController())
    );

    // add copy keyboard command
    ComponentKeyBinding.install(controller, viewerComponentPanel);

    // Build a viewer component
    SwingViewBuilder factory = new SwingViewBuilder(controller);

    InputStream is = new ByteArrayInputStream(outputStream.toByteArray());
    controller.openDocument(is, "", "\\test.pdf");
    controller.setIsEmbeddedComponent(true);

    JPanel viewerComponentPanel = factory.buildViewerPanel();

    // Create JFrame to contain the viewer
    JFrame viewerFrame = new JFrame();
    viewerFrame.getContentPane().add(viewerComponentPanel);
    viewerFrame.pack();
    viewerFrame.setVisible(true);
}

Hi! Your provided solution worked like a charm, I am not sure why -new keyword added to Pdf Name Say I name pdf file as My Report.pdf, it auto rename it to My Report-new.pdf!

My final working code!

// Open the generated PDF in the icepdf-viewer
private void openPdfInViewer(ByteArrayOutputStream outputStream) {
    // Create a SwingController
    SwingController controller = new SwingController();

    // Create the viewer as a JPanel
    controller.getDocumentViewController().setAnnotationCallback(
            new MyAnnotationCallback(controller.getDocumentViewController())
    );

    InputStream is = new ByteArrayInputStream(outputStream.toByteArray());
    controller.openDocument(is, "", "\\test.pdf");
    controller.setIsEmbeddedComponent(true);

    // Build a viewer component
    SwingViewBuilder factory = new SwingViewBuilder(controller);

    JPanel viewerComponentPanel = factory.buildViewerPanel();

    ComponentKeyBinding.install(controller, viewerComponentPanel);

    // add copy keyboard command
    ComponentKeyBinding.install(controller, viewerComponentPanel);

    // Create JFrame to contain the viewer
    JFrame viewerFrame = new JFrame();
    viewerFrame.getContentPane().add(viewerComponentPanel);
    viewerFrame.pack();
    viewerFrame.setVisible(true);
}

Still if file extension e.g. PDF Document (*.pdf) can be added it will me more cool, for example see below!

Moreover: Save As dialog's Icon & Name can be changed?

[pcorless]

To customise the icon and name you'll have to extend SwingController and override the method void saveFileAs(SaveMode saveMode).
the JFileChooser can be configured as you see fit. The api doesn't offer that level of customisation. Since you're using JavaFX you could code something to take advantage the new UI component. Either way make sure you call saveFileChecks(...)

I am not sure, how can i extend SwingController() to achive similar result, I will take a deeply looks at this to solve my given problem.

Sorry I totally missed this thread. Is it still an issue for your?

[ctoabidmaqbool1]

As you solutions in other issue, solved my problem e.g. Cross refference loading failed,
