如何更改 XSSFTextBox 上的字体

Question

XSSFTextBox 和 XSSFRichTextField 的

编辑见评论； Apache POI 似乎是种族主义者，不支持黑人？红色是？

编辑 2：在字体中使用常量而不是 XSSFColor，它们有红色和黑色；查看默认字体（只是为了清楚代码现在正确显示颜色和大小，但字体名称/实际字体仍然是错误的。所以 Font.COLOR_NORMAL 适用于 dat black）

由于某种原因，我无法让我的 XSSFTextBoxs 文本的字体和字体颜色从它们（我假设）默认的 Calibri 白色（为什么默认是白色？！？）。我改变了它们的大小，但它们的字体和字体颜色保持默认值。我发现这是以前的错误，应该修复here。

我一直在查看this 对我如何更改字体的基础的引用，看起来它就是这样做的，但它似乎不起作用；我希望对此有另一种看法，还有其他一些小问题我仍在摆弄，但字体实现是目前最重要的事情；欢迎提出任何批评意见！

真正让我感到厌烦的是，我以前非常广泛地将 XSSFFont 与 XSSFCellStlyes 一起使用，并且在更改字体或颜色时从未遇到任何问题，更不用说其他任何问题了，所以我不知道这是不是我的一些奇怪行为'没有看到，或者我在这里做错了什么。

这很粗略，但是在 poi 3.9 中，似乎只有字体系列而不是字体名称是从 XSSFSimpleShape.applyAttributes 中的 XSSFFont 对象复制而来的。 此外，我只能通过XSSFColor.setColor(HSSFColor.<color>.index) 设置索引颜色 - 也许HSSF custom color palette 有 XSSF 挂件，但我认为下面的方法更直接......

（使用 Libre Office 4.0、MS Excel Viewer、MS Excel 2003 与兼容包测试...）

import java.awt.Color;
import java.io.*;
import org.apache.poi.xssf.usermodel.*;
import org.openxmlformats.schemas.drawingml.x2006.main.CTTextCharacterProperties;

public class XlsColors {

    static String fileName = "TestWorkbook.xlsx";

    public static void main(String[] args) throws Exception {
        XSSFWorkbook wb = new XSSFWorkbook();
        XSSFSheet sht = wb.createSheet();
        File file = new File(fileName);
        int colStart = 5;

        XSSFDrawing draw = sht.createDrawingPatriarch();

        XSSFShapeGroup group = draw.createGroup(draw.createAnchor(0, 0, 0, 0, colStart, 11, colStart + 6, 11+7));
        group.setCoordinates(colStart, 11, colStart + 6, 11+7);

        XSSFTextBox tb1 = group.createTextbox(new XSSFChildAnchor(0, 0, 6, 7));
        tb1.setLineStyleColor(0, 0, 0);
        tb1.setLineWidth(2);
        Color col = Color.orange;
        tb1.setFillColor(col.getRed(), col.getGreen(), col.getBlue());

        XSSFRichTextString address = new XSSFRichTextString("TextBox string 1\nHas three\nLines to it");
        tb1.setText(address);        
        CTTextCharacterProperties rpr = tb1.getCTShape().getTxBody().getPArray(0).getRArray(0).getRPr();
        rpr.addNewLatin().setTypeface("Trebuchet MS");
        rpr.setSz(900); // 9 pt
        col = Color.pink;
        rpr.addNewSolidFill().addNewSrgbClr().setVal(new byte[]{(byte)col.getRed(),(byte)col.getGreen(),(byte)col.getBlue()});

        FileOutputStream fout = new FileOutputStream(file);
        wb.write(fout);
        fout.close();
    }
}
