【Java】Insert or Delete Text Boxes in Word Documents

Text boxes in Word documents are a container that saves editable text or images. You add them to documents for extra visual appeal or to call out sections of text within the document. This article will demonstrate how to insert a text box with an image and text in a Word document and delete it from the document using Java programmatically.

Before typing codes

At first, you need to download a free third-party library Free Spire.Doc for Java from the link, unzip it and then find Spire.Doc.jar in the “lib” folder. Finally, add Spire.Doc.jar to your IDEA. Here is a screenshot of final look in IDEA.

Using the code

Insert a Text Box

Free Spire.Doc for Java provides the method Paragraph.AppendTextBox to enable users to insert a text box in specified paragraph of Word document, and an image, text or table can be added to the text box in the process of inserting it. Here are detailed steps to insert a text box with an image and text in Word.

Step 1: Load a Word document and append a text box with specified size to specified paragraph;

Step 2: Set Format properties, including TextWrappingStyle, HorizontalPosition, VerticalPosition, LineStyle and LineColor.

Step 3: Declare a new Paragraph and insert an image using the appendPicture method. Next, set properties for the image, including Height, Width, HorizontalAlignment.

Step 4: insert text by using the appendText method and set CharacterFormat properties, including FontName and FonSize.

Step 5: Using the saveToFile method to saving the resulting document.

import com.spire.doc.documents.*;
import com.spire.doc.fields.DocPicture;
import com.spire.doc.fields.TextBox;
import com.spire.doc.fields.TextRange;

import java.awt.*;
public class AddTextBox {
    public static void main(String[] args) {
        //load a Word document
        Document doc = new Document();
        doc.loadFromFile("C:\\Users\\Test1\\Desktop\\Sample.docx");

        //append a textbox to paragraph
        TextBox tb = doc.getSections().get(0).addParagraph().appendTextBox(100f, 320f);

        //set the text wrapping style
        tb.getFormat().setTextWrappingStyle(TextWrappingStyle.Square);

        //set the position of textbox
        tb.getFormat().setHorizontalOrigin(HorizontalOrigin.Right_Margin_Area);
        tb.getFormat().setHorizontalPosition(-100f);
        tb.getFormat().setVerticalOrigin(VerticalOrigin.Page);
        tb.getFormat().setVerticalPosition(100f);

        //set the border style of textbox
        tb.getFormat().setLineStyle(TextBoxLineStyle.Thin_Thick);
        tb.getFormat().setLineColor(new Color(240,135,152));

        //insert an image to textbox as the first paragraph
        Paragraph para = tb.getBody().addParagraph();
        DocPicture picture = para.appendPicture("C:\\Users\\Test1\\Desktop\\Image.jpg");
        picture.setHeight(60f);
        picture.setWidth(90f);
        para.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
        para.getFormat().setAfterSpacing(15f);

        //insert text to textbox as the second paragraph
        para = tb.getBody().addParagraph();
        TextRange textRange = para.appendText("A cashless society is one in which financial transactions are handled " +
                "through the transfer of digital information instead of physical money in the form of banknotes or coins.");
        textRange.getCharacterFormat().setFontName("Times New Roman");
        textRange.getCharacterFormat().setFontSize(12f);
        para.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);

        //save to file
        doc.saveToFile("output/InsertTextbox.docx", FileFormat.Docx_2013);
    }
}

Output

Remove a Text Box

Using several rows of code snippets provided by Free Spire.Doc for Java, you can easily remove a specified text box or all text boxes in Word.

import com.spire.doc.Document;

How to insert or remove page breaks in Excel Worksheets using Java

When we’re printing a large Excel worksheet, in order to exactly control which and how many rows and columns appear on the printed pages, we need to insert page breaks to specify where a new page will begin. This article will demonstrate how to insert or remove page breaks in Excel worksheet using Java programmatically. Please note that Page Breaks is only visible in the View menu tab under Workbook Views with the name of Page Break Preview.

Creating a Test Environment

Before typing codes, you should create a test environment by installing JDK, Intellij IDEA and Free Spire.XLS for Java which can be gained through E-iceblue website. After downloading the package, unzip it and manually add Spire.Xls.jar in the “lib” folder to your IDEA.

Of course, if you’re creating a Maven project, the best method is to install Free Spire.XLS for Java from Maven repository. The only thing you need to do is typing the following codes in the pom.xml file and clicking the button “Import Changes”.

Add Page Breaks to Excel worksheet
Free Spire.XLS for Java provides a method to help us insert page breaks horizontally and vertically.
After adding page breaks, we can set view mode as Page Break Preview which displays excel
as it will be printed. 

import com.spire.xls.*;

public class AddPageBreak {

    public static void main(String[] args) {

        //Create a Workbook instance and load the sample file

        Workbook workbook = new Workbook();

        workbook.loadFromFile("C:\\Users\\Test1\\Desktop\\Sample.xlsx");

        //Get the second worksheet

        Worksheet sheet = workbook.getWorksheets().get(1);

        //Set Excel Page Break Horizontally

        sheet.getHPageBreaks().add(sheet.getRange().get("A6"));

        //Set Excel Page Break Vertically

        sheet.getVPageBreaks().add(sheet.getRange().get("C1"));

        sheet.getVPageBreaks().add(sheet.getRange().get("E1"));

        // Set the ViewMode as Preview mode 

        workbook.getWorksheets().get(0).setViewMode(ViewMode.Preview);

        //Save the document

        workbook.saveToFile("output/AddPageBreak.xlsx", ExcelVersion.Version2013);

    }

}
Output



Remove Page Breaks in Excel worksheet
In addition to inserting page breaks, Free Spire.XLS for Java supports removing the special page breaks in Excel
worksheet. Here comes to the steps of how to do it.
Step 1: Initialize a Workbook instance and load the sample file.
Step 2: Get the second worksheet from the workbook.
Step 3: Clear all the vertical page breaks and remove the first horizontal page break.
Step 4: Set the ViewMode as Preview to see how the page breaks work.
