Class NodeChangingArgs

  • java.lang.Object
    • com.aspose.words.NodeChangingArgs
public class NodeChangingArgs 
extends java.lang.Object

Provides data for methods of the INodeChangingCallback interface.

Example:

Shows how to implement custom logic over node insertion in the document by changing the font of inserted HTML content.
public void testNodeChangingInDocument() throws Exception
{
    // Create a blank document object
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    // Set up and pass the object which implements the handler methods.
    doc.setNodeChangingCallback(new HandleNodeChanging_FontChanger());

    // Insert sample HTML content
    builder.insertHtml("<p>Hello World</p>");

    doc.save(getMyDir() + "\\Artifacts\\Document.FontChanger.doc");

    // Check that the inserted content has the correct formatting
    Run run = (Run) doc.getChild(NodeType.RUN, 0, true);
    Assert.assertEquals(run.getFont().getSize(), 24.0);
    Assert.assertEquals(run.getFont().getName(), "Arial");
}

public class HandleNodeChanging_FontChanger implements INodeChangingCallback
{
    // Implement the NodeInserted handler to set default font settings for every Run node inserted into the Document
    public void nodeInserted(NodeChangingArgs args)
    {
        // Change the font of inserted text contained in the Run nodes.
        if (args.getNode().getNodeType() == NodeType.RUN)
        {
            Font font = ((Run) args.getNode()).getFont();
            font.setSize(24);
            font.setName("Arial");
        }
    }

    public void nodeInserting(NodeChangingArgs args)
    {
        // Do Nothing
    }

    public void nodeRemoved(NodeChangingArgs args)
    {
        // Do Nothing
    }

    public void nodeRemoving(NodeChangingArgs args)
    {
        // Do Nothing
    }
}
